Philosophical speculation (Books)

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service."

BG 8.9, Purport:

Acintya means that which is beyond this material world, that which our argument, logic and philosophical speculation cannot touch, that which is inconceivable. Therefore intelligent persons, avoiding useless argument and speculation, should accept what is stated in scriptures like the Vedas, Bhagavad-gītā and Śrīmad-Bhāgavatam and follow the principles they set down. This will lead one to understanding.

BG 11.52, Purport:

One may be able to see the universal form of Kṛṣṇa by adding a little tinge of devotional service to various activities like penances, Vedic study and philosophical speculation. It may be possible, but without a tinge of bhakti one cannot see; that has already been explained. Still, beyond that universal form, the form of Kṛṣṇa with two hands is still more difficult to see, even for demigods like Brahmā and Lord Śiva.

BG 11.54, Purport:

No one can understand Kṛṣṇa or how He came from parents in a four-handed form and at once changed Himself into a two-handed form. These things are very difficult to understand by study of the Vedas or by philosophical speculation. Therefore it is clearly stated here that no one can see Him or enter into understanding of these matters.

BG Chapters 13 - 18

BG 13.8-12, Purport:

There are many research scholars and philosophers who study sex life or some other subject, but according to Bhagavad-gītā such research work and philosophical speculation have no value. That is more or less nonsensical. According to Bhagavad-gītā, one should make research, by philosophical discretion, into the nature of the soul. One should make research to understand the self.

BG 14.1, Purport:

From the Seventh Chapter to the end of the Twelfth Chapter, Śrī Kṛṣṇa in detail reveals the Absolute Truth, the Supreme Personality of Godhead. Now, the Lord Himself is further enlightening Arjuna. If one understands this chapter through the process of philosophical speculation, he will come to an understanding of devotional service.

BG 15.19, Purport:

There are many philosophical speculations about the constitutional position of the living entities and the Supreme Absolute Truth. Now in this verse the Supreme Personality of Godhead clearly explains that anyone who knows Lord Kṛṣṇa to be the Supreme Person is actually the knower of everything. The imperfect knower goes on simply speculating about the Absolute Truth, but the perfect knower, without wasting his valuable time, engages directly in Kṛṣṇa consciousness, the devotional service of the Supreme Lord.

BG 18.78, Purport:

From Bhagavad-gītā we can understand that to realize oneself by philosophical speculation and by meditation is one process, but to fully surrender unto Kṛṣṇa is the highest perfection. This is the essence of the teachings of Bhagavad-gītā.

Srimad-Bhagavatam

SB Canto 1

SB 1.1.7, Purport:

Theism is explained completely in the Vedānta-sūtra, whereas in other systems of philosophical speculations, practically no mention is given to the ultimate cause of all causes. One can sit on the vyāsāsana only after being conversant in all systems of philosophy so that one can present fully the theistic views of the Bhāgavatam in defiance of all other systems.

SB 1.1.16, Purport:

Those who are engaged in the pure devotional service of the Lord, who are without any desire for self-aggrandizement and who are freed from the effects of fruitive actions and dry philosophical speculations are capable of getting out of the estrangements of this complicated age.

SB 1.2.6, Purport:

Renunciation or abnegation for ultimate good is certainly a better occupation than enjoyment in the diseased condition of life. Such enjoyment only aggravates the symptoms of disease and increases its duration. Therefore devotional service to the Lord must be pure in quality, i.e., without the least desire for material enjoyment. One should, therefore, accept the superior quality of occupation in the form of the devotional service of the Lord without any tinge of unnecessary desire, fruitive action and philosophical speculation. This alone can lead one to perpetual solace in His service.

SB 1.4.32, Purport:

Although Vyāsadeva was an empowered divinity, he still felt dissatisfaction because in none of his works were the transcendental activities of the Lord properly explained. The inspiration was infused by Śrī Kṛṣṇa directly in the heart of Vyāsadeva, and thus he felt the vacuum as explained above. It is definitely expressed herewith that without the transcendental loving service of the Lord, everything is void; but in the transcendental service of the Lord, everything is tangible without any separate attempt at fruitive work or empiric philosophical speculation.

SB 1.5.8, Purport:

Dry philosophical speculations even on the transcendental subject of the Absolute have very little attraction without directly dealing with the glorification of the Lord.

SB 1.5.13, Purport:

People in general have a taste for literatures by instinct. They want to hear and read from the authorities something about the unknown, but their taste is exploited by unfortunate literatures which are full of subject matter for satisfaction of the material senses. Such literatures contain different kinds of mundane poems and philosophical speculations, more or less under the influence of māyā, ending in sense gratification.

SB 1.5.22, Purport:

Philosophy and science should be engaged to establish the glory of the Lord. Advanced people are eager to understand the Absolute Truth through the medium of science, and therefore a great scientist should endeavor to prove the existence of the Lord on a scientific basis. Similarly, philosophical speculations should be utilized to establish the Supreme Truth as sentient and all-powerful.

SB 1.5.37, Purport:

Nāradajī has therefore explained the nature of unalloyed devotional service by his personal experience in the development of intimacy between the Lord and the living entity by a gradual process of progressive devotional activities. Such a progressive march of transcendental devotion for the Lord culminates in the attainment of loving service of the Lord, which is called premā in different transcendental variegatedness called rasas (tastes). Such devotional service is also executed in mixed forms, namely mixed with fruitive work or empiric philosophical speculations.

SB 1.5.38, Purport:

The pāñcarātrika system has the most authorized codes for transcendental devotional service. Without the help of such codes, one cannot approach the Lord, certainly not by dry philosophical speculation. The pāñcarātrika system is both practical and suitable for this age of quarrel. The Pañcarātra is more important than the Vedānta for this modern age.

SB 1.6.31, Purport:

The ṛṣis, as above mentioned, cannot enter into the transcendental world like Nārada. This fact is disclosed in the Narasiṁha Purāṇa. Ṛṣis like Marīci are authorities in fruitive work, and ṛṣis like Sanaka and Sanātana are authorities in philosophical speculations. But Śrī Nārada Muni is the prime authority for transcendental devotional service of the Lord.

SB 1.6.35, Purport:

The whole idea is that without devotional service of the Lord, neither the yoga system nor dry philosophical speculation can ever become successful. Pure devotional service of the Lord, without being tinged with fruitive work, mystic yoga or speculative philosophy, is the foremost procedure to attain self-realization.

SB 1.10.36, Purport:

It is said here that the Lord observed the religious principles regularly while He was on the journey. There are certain philosophical speculations that even the Lord is under the obligations of fruitive action. But actually this is not the case. He does not depend on the action of any good or bad work. Since the Lord is absolute, everything done by Him is good for everyone.

SB 1.11.8, Purport:

Neither Brahmājī nor the demigods like Indra can enter into this island of Śvetadvīpa, but they can stand on the shore of the ocean of milk and transmit their message to Lord Viṣṇu, known as Kṣīrodakaśāyī Viṣṇu. Therefore, the Lord is rarely seen by them, but the inhabitants of Dvārakā, because of their being pure devotees without any tinge of the material contamination of fruitive activities and empiric philosophical speculation, can see Him face to face by the grace of the Lord.

SB 1.13.2, Purport:

So neither fruitive activities nor dry philosophical speculation can give one satisfaction because by nature a living being is the eternal servitor of the Supreme Lord Śrī Kṛṣṇa, and all the Vedic literatures give him direction towards that ultimate end. The Bhagavad-gītā (15.15) confirms this statement.

SB 1.15.45, Purport:

According to Svāmī Śrīdhara, dharma, artha, kāma and mokṣa, or fruitive activities, philosophical speculations and salvation, as conceived by several persons, are not the ultimate goal of life. They are more or less practiced by persons who have no information of the ultimate goal of life.

SB 1.18.12, Purport:

In the Brahma-vaivarta Purāṇa, Viṣṇu tells Śiva that in the age of Kali, men full of anxieties of various kinds can vainly labor in fruitive activity and philosophical speculations, but when they are engaged in devotional service, the result is sure and certain, and there is no loss of energy.

SB 1.18.13, Purport:

Men who are addicted to material happiness aspire to reach the heavenly planets like the moon, Venus and Indraloka, and those who are advanced in material philosophical speculations aspire after liberation from all material bondage.

SB 1.18.22, Purport:

Only the self-controlled can gradually be attached to the Supreme Personality of Godhead. Self-controlled means not indulging in sense enjoyment more than is necessary. And those who are not self-controlled are given over to sense enjoyment. Dry philosophical speculation is a subtle sense enjoyment of the mind.

SB Canto 2

SB 2.1.9, Purport:

The Absolute Truth is realized as the impersonal Brahman at the first instance by philosophical speculation and later as the Supersoul by further progress of transcendental knowledge.

SB 2.2.15, Purport:

In the Bhagavad-gītā (8.14) it is clearly stated that a person who is totally engaged in the transcendental loving service of the Lord, and who constantly remembers Him at every step, easily obtains the mercy of the Lord by entering into His personal contact. Such devotees do not need to seek an opportune moment to leave the present body. But those who are mixed devotees, alloyed with fruitive action or empirical philosophical speculation, require an opportune moment for quitting this body

SB 2.4.17, Purport:

Advancement of learning, a charitable disposition, political, social or religious leadership of human society, philosophical speculations, the practice of the yoga system, expertise in the Vedic rituals, and all similar high qualities in man serve one in the attainment of perfection only when they are employed in the service of the Lord.

SB 2.4.23, Purport:

The Vedic truths are all perfect descriptions of the factual truth without any mistake or illusion, and Śukadeva Gosvāmī wants to present the truths of creation not as a metaphysical theory of philosophical speculation, but as the actual facts and figures of the subject, since he would be dictated to by the Lord exactly in the same manner as Brahmājī was inspired.

SB 2.6.38, Purport:

As the senses are progressively purified by bona fide devotional service, the Lord reveals His identity according to the spiritual advancement of the devotee. But one who is not in the line of devotional service can hardly perceive Him simply by calculations and philosophical speculations. Such a hard worker can present a jugglery of words before an audience, but can never know the Supreme Personality of Godhead in His personal feature.

SB 2.9.18, Purport:

Lord Brahmā said, "O my Lord Kṛṣṇa, a devotee who abandons the path of empiric philosophical speculation aimed at merging in the existence of the Supreme and engages himself in hearing Your glories and activities from a bona fide sādhu, or saint, and who lives an honest life in the occupational engagement of his social life, can conquer Your sympathy and mercy even though You are ajita, or unconquerable." (SB 10.14.3) That is the path of the paramahaṁsas, which was personally followed by Lord Brahmā and later recommended by him for attaining perfect success in life.

SB Canto 3

SB 3.1.31, Purport:

The empiric philosophers enjoy a transcendental quality of bliss by philosophical speculation on the Supreme Truth, but beyond that pleasure is the pleasure enjoyed by Brahman in His eternal form of the Personality of Godhead.

SB 3.3.26, Purport:

The sādhana-siddha devotees are chosen from the conditioned souls. Out of the sādhana devotees, there are mixed and pure devotees. The mixed devotees are sometimes enthusiastic about fruitive activities and are habituated to philosophical speculation. The pure devotees are free from all these mixtures and are completely absorbed in the service of the Lord, regardless of how and where they are situated.

SB 3.4.11, Purport:

In the days of yore, when the demigods and Vasus performed sacrifice, Uddhava, as one of the Vasus, desired to enter into the association of the Lord, which is very difficult for those busy in empiric philosophical speculation or fruitive activities.

SB 3.4.16, Purport:

Pure devotees of the Lord are not very much concerned with philosophical speculation in regard to transcendental knowledge of the Lord. Nor is it possible to acquire complete knowledge of the Lord. Whatever little knowledge they have about the Lord is sufficient for them because devotees are simply satisfied in hearing and chanting about the transcendental pastimes of the Lord.

SB 3.5.4, Purport:

The most capable transcendentalist is the pure devotee of the Lord, who is without any tinge of fruitive actions or philosophical speculation.

SB 3.5.14, Translation:

O sage, persons who because of their sinful activities are averse to the topics of Transcendence and thus ignorant of the purpose of the Mahābhārata (Bhagavad-gītā) are pitied by the pitiable. I also pity them because I see how their duration of life is spoiled by eternal time while they involve themselves in presentations of philosophical speculation, theoretical ultimate goals of life, and different modes of ritual.

SB 3.5.31, Purport:

The best means of liberation from the clutches of false ego is to give up the habit of philosophical speculation regarding the Absolute Truth.

SB 3.5.31, Purport:

One should know definitely that the Absolute Truth is never realized by the philosophical speculations of the imperfect egoistic person. The Absolute Truth, or the Supreme Personality of Godhead, is realized by hearing about Him in all submission and love from a bona fide authority who is a representative of the twelve great authorities mentioned in the Śrīmad-Bhāgavatam.

SB 3.5.40, Purport:

Empiric philosophical speculation cannot give one relief from the threefold miseries of material existence. Simply to endeavor for knowledge without devoting oneself to the Lord is a waste of valuable time.

SB 3.7.12, Purport:

The quivering quality of material existence, which comes from identification with matter or from thinking oneself, under the material influence of philosophical speculation, to be God, can be eradicated by devotional service to the Lord, by the mercy of the Personality of Godhead, Vāsudeva.

SB 3.7.12, Purport:

Pure devotees of the Lord are transcendental to all material desires, including the desire for the results of fruitive activities and philosophical speculation. If one wants to acquire the mercy of the Lord, he has to associate with pure devotees. Such association alone can, by degrees, release one from the quivering elements.

SB 3.19.22, Purport:

In Bhagavad-gītā the Lord confirms that He is the beneficiary and enjoyer of all sacrifices, penances and austerities. The Lord is the enjoyer of three kinds of yajña. As further described in Bhagavad-gītā, there are sacrifices of goods, sacrifices of meditation and sacrifices of philosophical speculation. Those on the paths of jñāna, yoga and karma all have to come in the end to the Supreme Lord because vāsudevaḥ sarvam iti (BG 7.19)—the Supreme Lord is the ultimate enjoyer of everything. That is the perfection of all sacrifice.

SB 3.27.17, Purport:

Although one may understand that spirit soul and matter are different, their actual separation is not possible, either by philosophical speculation or by proper understanding.

SB 3.27.23, Purport:

Since a devotee also engages in philosophical research to understand the Supreme Person as He is, his activities may thus appear to be like those of a mental speculator, but actually he is trying to understand the spiritual nature and transcendental activities. Thus although the tendency for philosophical speculation exists, the material effects of fruitive activities and empiric speculation do not, because this activity is meant for the Supreme Personality of Godhead.

SB 3.29.10, Purport:

Pure devotional service as described by Rūpa Gosvāmī is free from all material desires. Anyābhilāṣitā-śūnyam (CC Madhya 19.167). There can be no excuse for personal or material interest. Devotional activities should be transcendental to fruitive activities and empiric philosophical speculation. Pure devotional service is transcendental to all material qualities.

SB 3.32.32, Purport:

The opportunity for direct touch with the Personality of Godhead is given in Bhagavad-gītā, where it is also said that those who take to other processes, namely the processes of philosophical speculation and mystic yoga practice, have much trouble. After many, many years of much trouble, a yogī or wise philosopher may come to Him, but his path is very troublesome, whereas the path of devotional service is easy for everyone.

SB 3.32.32, Purport:

One can achieve the result of wise philosophical speculation simply by discharging devotional service, and unless one reaches the point of understanding the Personality of Godhead by his mental speculation, all his research work is said to be simply a labor of love.

SB 3.32.33, Purport:

It appears that by following the path of jñāna-yoga, or empiric philosophical speculation, one reaches the impersonal Brahman, whereas by executing devotional service in Kṛṣṇa consciousness one enriches his faith in and devotion to the Personality of Godhead.

SB 3.33.10, Purport:

Devotional service is so perfect that simply by following the rules and regulations and executing them under the direction of the spiritual master, one is liberated, as it is said herein, from the clutches of māyā, even in this body. In other yogic processes, or in empiric philosophical speculation, one is never certain whether or not he is at the perfectional stage. But in the discharge of devotional service, if one has unflinching faith in the instruction of the bona fide spiritual master and follows the rules and regulations, he is sure to be liberated, even within this present body.

SB 3.33.22, Purport:

Unless we are able to transfer our attachment to the Supreme Personality of Godhead, there is no possibility of becoming freed from material attachment. The Śrīmad-Bhāgavatam, therefore, confirms that it is not possible for one to become liberated by cultivation of empiric philosophical speculation. Simply knowing that one is not matter but spirit soul, or Brahman, does not purify one's intelligence. Even if the impersonalist reaches the highest platform of spiritual realization, he falls down again to material attachment because of not being situated in the transcendental loving service of the Supreme Lord.

SB Canto 4

SB 4.7.42, Translation:

The demigods said: Dear Lord, formerly, when there was a devastation, You conserved all the different energies of material manifestation. At that time, all the inhabitants of the higher planets, represented by such liberated souls as Sanaka, were meditating on You by philosophical speculation. You are therefore the original person, and You rest in the water of devastation on the bed of the Śeṣa snake. Now, today, You are visible to us, who are all Your servants. Please give us protection.

SB 4.9.6, Purport:

Without revelation by the spiritual energy, one is unable to offer prayers glorifying the Lord. Any amount of philosophical speculation or poetic expression by mundane persons is still considered to be the action and reaction of the material energy. When one is actually enlivened by the spiritual energy, all his senses become purified, and he engages only in the service of the Lord.

SB 4.9.31, Purport:

The Vaiṣṇava philosophy in the process of Kṛṣṇa consciousness prohibits the devotee from all kinds of material aspirations. A Vaiṣṇava devotee should always be anyābhilāṣitā-śūnya, free from all material aspirations for the results of fruitive activities or empiric philosophical speculation.

SB 4.11.23, Purport:

The Lord gives one the intelligence to cross over the ocean of nescience and come back home, back to Godhead. In conclusion, the cause of all causes, the Absolute Truth, or Supreme Brahman, cannot be understood by philosophical speculation, but He reveals Himself to His devotee because the devotee fully surrenders unto His lotus feet.

SB 4.12.51, Purport:

No one knows actually what is the Absolute Truth. Materialists are very proud of their advancement in education, in philosophical speculation and in scientific knowledge, but no one actually knows what the Absolute Truth is.

SB 4.20.12, Purport:

Jñānīs try to get out of entanglement by philosophical speculation, but they have no standing in the liberated position. Because they do not take shelter under the lotus feet of the Lord, they fall down from the exalted position of Brahman realization.

SB 4.20.31, Purport:

The conclusion is that the pure devotee should not aspire after any material benefit from devotional service, nor should he be enamored by fruitive activities or philosophical speculation. He should always be engaged favorably in the service of the Lord. That is the highest perfection of life.

SB 4.22.39, Purport:

The jñānīs and yogīs, who are not attached to the lotus feet of the Lord, simply struggle against the waves of desire. They are described in this verse as rikta-matayaḥ, which means "devoid of devotional service." In other words, the jñānīs and yogīs, although trying to be free from the desires of material activities, actually become more and more entangled in false philosophical speculation or strenuous attempts to stop the activities of the senses.

SB 4.23.11, Purport:

The karmīs are very much attached to material enjoyment, the jñānīs are very anxious to become freed from material clutches, and the yogīs are very fond of attaining the eight kinds of mystic perfection. From the Nārada-pañcarātra we understand that if one attains the stage of pure devotional service, he also attains all the opulences derived from fruitive activities, empiric philosophical speculation and mystic yogic practice.

SB 4.23.11, Purport:

Śrīla Bilvamaṅgala Ṭhākura therefore prayed in his Kṛṣṇa-karṇāmṛta: "My dear Lord, if I have unflinching devotion to You, You become manifest before me personally, and the results of fruitive activity and empiric philosophical speculation—namely religion, economic development, sense gratification and liberation—become like personal attendants and remain standing before me as if awaiting my order."

SB 4.23.28, Purport:

Jñānīs are engaged in philosophical speculation in order to gain release from the clutches of material nature.

SB 4.28.28, Purport:

If a person falls from the path of bhakti-yoga, God realization, due to attachment to fruitive activity, philosophical speculation or mystic yoga, he is given a chance to take birth in a high and rich family.

SB 4.29.65, Purport:

A pure devotee, who is free from all material desires experienced on the mental platform and who is also free from empiric philosophical speculation or fruitive activity, is always above material conditioning and is always liberated.

SB 4.29.66, Purport:

All qualities that are considered good according to the material estimation actually have no value because these so-called good qualities will not save a person from the cycle of birth and death. The conclusion is that one should be without mental desire. Anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anāvṛtam: (CC Madhya 19.167) one should be fully free from material desires, philosophical speculation and fruitive activity. The best course for a human being is to favorably accept the transcendental devotional service of the Lord.

SB 4.31.9, Purport:

It is particularly mentioned herein that birth is successful if an interest in Kṛṣṇa consciousness is taken. Activity is successful if it results in serving the Lord. Philosophical speculation or mental speculation is successful when engaged in understanding the Supreme Personality of Godhead. The senses are worth possessing when engaged in the service of the Lord.

SB Canto 5

SB 5.5.7, Purport:

In the lowest stage of devotional life, one is not an unalloyed devotee. Anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anāvṛtam: (CC Madhya 19.167) to be an unalloyed devotee, one must be freed from all material desires and untouched by fruitive activity and speculative knowledge. On the lower platform, one may sometimes be interested in philosophical speculation with a tinge of devotion. However, at that stage one is still interested in sense gratification and is contaminated by the modes of material nature.

SB 5.5.14, Purport:

Even those who are liberated (ātmārāma) must always engage in devotional service. One may give up the practice of yoga when one is self-realized, but at no stage can one give up devotional service. All other activities for self-realization, including yoga and philosophical speculation, may be given up, but devotional service must be retained at all times.

SB 5.17.11, Purport:

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service." Those who fully engage in devotional service to Kṛṣṇa just to please Him are not interested in the three divisions of heavenly places, namely, divya-svarga, bhauma-svarga and bila-svarga.

SB 5.18.8, Purport:

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service." Unless one is completely freed of all material desires, which are caused by the dense darkness of ignorance, one cannot fully engage in the devotional service of the Lord.

SB 5.19.7, Purport:

He is a typical example of how a poor man with no material possessions can become a most exalted devotee of the Lord. The conclusion is that one cannot attain shelter at the lotus feet of Lord Kṛṣṇa or Śrī Caitanya Gosāñi through material opulence; that shelter is attainable only by pure devotional service.

anyābhilāṣitā-śūnyaṁ

jñāna-karmādy-anāvṛtam

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service."

SB Canto 6

SB 6.1.15, Purport:

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service." Śrīla Rūpa Gosvāmī further explains that bhakti is kleśaghnī śubhadā, which means if one takes to devotional service, all kinds of unnecessary labor and material distress cease entirely and one achieves all good fortune. Bhakti is so powerful that it is also said to be mokṣa-laghutākṛt; in other words, it minimizes the importance of liberation.

SB 6.4.31, Purport:

Since time immemorial or since the creation of the cosmic manifestation, the conditioned souls have formed various parties of philosophical speculation, but this is not true of the devotees. Nondevotees have different ideas of creation, maintenance and annihilation, and therefore they are called vādīs and prativādīs—proponents and counterproponents.

SB 6.4.31, Purport:

The demoniac speculators cannot understand the transcendental qualities, form, pastimes, strength, knowledge and opulence of the Supreme Personality of Godhead, which are all free from material contamination (vinā heyair guṇādibhiḥ). These speculators are envious of the existence of the Lord. Jagad āhur anīśvaram: their conclusion is that the entire cosmic manifestation has no controller, but is just working naturally. Thus they are kept in constant darkness, birth after birth, and cannot understand the real cause of all causes. This is the reason why there are so many schools of philosophical speculation.

SB 6.15.4, Purport:

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service." One should act only to develop Kṛṣṇa consciousness. For everything else, one should fully depend upon the Supreme Person. We should not create plans that will ultimately make us frustrated.

SB 6.16.40, Purport:

As stated by Śrīla Rūpa Gosvāmī in Bhakti-rasāmṛta-sindhu:

anyābhilāṣitā-śūnyaṁ

jñāna-karmādy-anāvṛtam

ānukūlyena kṛṣṇānu-

śīlanaṁ bhaktir uttamā

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desires for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service."

SB Canto 7

SB 7.5.23-24, Purport:

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service." One should simply satisfy Kṛṣṇa, without being influenced by fruitive knowledge or fruitive activity.

SB 7.9.49, Purport:

After understanding the Supreme Lord through devotional service, such devotees are no longer interested in studies of the Vedas. Indeed, this is confirmed in the Vedas also. The Vedas say, kim arthā vayam adhyeṣyāmahe kim arthā vayam vakṣyāmahe. What is the use of studying so many Vedic literatures? What is the use of explaining them in different ways? Vayam vakṣyāmahe. No one needs to study any more Vedic literatures, nor does anyone need to describe them by philosophical speculation.

SB 7.13.24, Purport:

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service." (Bhakti-rasāmṛta-sindhu 1.1.11)

SB Canto 8

SB 8.3.20-21, Purport:

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service." Unalloyed devotees have nothing to ask from the Supreme Personality of Godhead, but Gajendra, the King of the elephants, was circumstantially asking for an immediate benediction because he had no other way to be rescued.

SB 8.5.31, Purport:

Atheists think that they are independent, and therefore they do not care about the supremacy of the Lord, yet the Lord asserts His supremacy when He overcomes them as death. At the time of death, their attempts to use their so-called scientific knowledge and philosophical speculation to deny the supremacy of the Lord cannot work.

SB 8.14.10, Translation:

People in general are bewildered by the illusory energy, and therefore they try to find the Absolute Truth, the Supreme Personality of Godhead, through various types of research and philosophical speculation. Nonetheless, they are unable to see the Supreme Lord.

SB 8.17.2-3, Purport:

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service." One simply has to concentrate upon the lotus feet of Vāsudeva, Kṛṣṇa (sa vai manaḥ kṛṣṇa-padāravindayoḥ (SB 9.4.18)). Then the mind and senses will be controlled, and one can engage himself fully in the devotional service of the Lord.

SB Canto 9

SB 9.5.22, Purport:

In Brahmaloka, everyone is self-realized, and thus there is no need of philosophical speculation to come to the conclusion of the Absolute Truth.

SB 9.21.16, Purport:

As stated in Bhagavad-gītā (7.20), kāmais tais tair hṛta jñānāḥ prapadyante 'nya-devatāḥ: those befooled by the illusion of the material energy worship gods other than the Supreme Personality of Godhead. Therefore, although Rantideva was personally able to see Lord Brahmā and Lord Śiva, he did not hanker to take material benefits from them. Rather, he fixed his mind upon Lord Vāsudeva and rendered devotional service unto Him. This is the sign of a pure devotee, whose heart is not adulterated by material desires.

SB Canto 10.1 to 10.13

SB 10.8.43, Purport:

Although mother Yaśodā understood the whole philosophy of life, at the next moment she was overwhelmed by affection for her son by the influence of yogamāyā. Unless she took care of her son Kṛṣṇa, she thought, how could He be protected? She could not think otherwise, and thus she forgot all her philosophical speculations. This forgetfulness is described by Śrīla Viśvanātha Cakravartī Ṭhākura as being inspired by the influence of yogamāyā (mohana-sādharmyān māyām). Materialistic persons are captivated by mahāmāyā, whereas devotees, by the arrangement of the spiritual energy, are captivated by yogamāyā.

SB Cantos 10.14 to 12 (Translations Only)

SB 11.12.9, Translation:

Even though one engages with great endeavor in the mystic yoga system, philosophical speculation, charity, vows, penances, ritualistic sacrifices, teaching of Vedic mantras to others, personal study of the Vedas, or the renounced order of life, still one cannot achieve Me.

SB 11.20.7, Translation:

Among these three paths, jñāna-yoga, the path of philosophical speculation, is recommended for those who are disgusted with material life and are thus detached from ordinary, fruitive activities. Those who are not disgusted with material life, having many desires yet to fulfill, should seek perfection through the path of karma-yoga.

Sri Caitanya-caritamrta

CC Adi-lila

CC Adi 2.13, Translation:

As with the naked eye one cannot know the sun except as a glowing substance, merely by philosophical speculation one cannot understand Lord Kṛṣṇa's transcendental varieties.

CC Adi 4.19, Purport:

The Vṛndāvana pastimes demonstrated that although generally people worship God with reverence, the Lord is more pleased when a devotee thinks of Him as his pet son, personal friend or most dear fiance and renders service unto Him with such natural affection. The Lord becomes a subordinate object of love in such transcendental relationships. Such pure love of Godhead is unadulterated by any tinge of superfluous nondevotional desires and is not mixed with any sort of fruitive action or empiric philosophical speculation.

CC Adi 4.21-22, Purport:

Fruitive activities ending in devotional service, philosophical speculation ending in devotional service, and the practice of mysticism ending in devotional service are known respectively as karma-yoga, jñāna-yoga and dhyāna-yoga. But such devotional service is adulterated by the three kinds of material activities.

CC Adi 4.21-22, Purport:

For those grossly engaged in identifying the body as the self, pious activity, or karma-yoga, is recommended. For those who identify the mind with the self, philosophical speculation, or jñāna-yoga, is recommended. But devotees standing on the spiritual platform have no need of such material conceptions of adulterated devotion.

CC Adi 7.18-19, Purport:

Unalloyed and internal devotees are both engaged in the favorable culture of Kṛṣṇa consciousness untinged by philosophical speculation or fruitive activities. They are all understood to be pure devotees, and those among them who simply engage in conjugal love are called mādhurya-bhaktas, or internal devotees.

CC Adi 7.33, Purport:

Māyā refers to material existence, which is characterized by the reactions of fruitive activities. Māyāvādīs consider devotional service to be among such fruitive activities. According to them, when bhāgavatas (devotees) are purified by philosophical speculation, they will come to the real point of liberation.

CC Adi 7.72, Purport:

Cheap Vaiṣṇavas (sahajiyās) do not care to study the Vedānta philosophy as commented upon by the four ācāryas. In the Gauḍīya-sampradāya there is a Vedānta commentary called the Govinda-bhāṣya, but the sahajiyās consider such commentaries to be untouchable philosophical speculation, and they consider the ācāryas to be mixed devotees. Thus they clear their way to hell.

CC Adi 7.146, Purport:

Māyāvādī philosophers, who do not understand the relationship between themselves, the cosmic manifestation and the Supreme Personality of Godhead, are simply wasting their time, and their philosophical speculation has no value.

CC Adi 13.64, Translation:

In these meetings of the Vaiṣṇavas, Advaita Ācārya used to recite the Bhagavad-gītā and Śrīmad-Bhāgavatam, decrying the paths of philosophical speculation and fruitive activity and establishing the superexcellence of devotional service.

CC Adi 13.65, Translation:

In all the revealed scriptures of Vedic culture, devotional service to Lord Kṛṣṇa is explained throughout. Therefore devotees of Lord Kṛṣṇa do not recognize the processes of philosophical speculation, mystic yoga, unnecessary austerity and so-called religious rituals. They do not accept any process but devotional service.

CC Adi 14.30, Translation:

Astonished that the child was speaking Māyāvāda philosophy, mother Śacī replied, "Who has taught You this philosophical speculation that justifies eating dirt?"

CC Adi 16.11, Purport:

If one diverts his attention to studying many books, he cannot fix his mind in devotional service, nor can he understand many scriptures, for they are full of grave statements and meanings. In this connection Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura gives his opinion that those who are attracted to studying many kinds of literature concerning various subject matters, especially fruitive activities and philosophical speculation, are deprived of unalloyed devotional service because of their splayed attention.

CC Adi 16.11, Purport:

Man has a general tendency toward fruitive activities, religious ritualistic ceremonies and philosophical speculation. A living entity thus bewildered since time immemorial does not understand the real goal of life, and thus his activities in life are wasted.

CC Adi 17.67, Translation:

Thus He whimsically began to explain the path of philosophical speculation, and the Lord, in His anger, seemingly disrespected Him.

CC Adi 17.68, Purport:

Advaita Prabhu's aspiration was to be a servant of the Lord, not His spiritual master. He therefore devised a plan to antagonize the Lord. He began to explain the path of philosophical speculation in the midst of some unfortunate Māyāvādīs, and when Lord Caitanya Mahāprabhu heard about this, He immediately went there and in a very angry mood began to beat Advaita Ācārya.

CC Adi 17.76, Purport:

If one wants to understand the Supreme Personality factually, he must take to the path of devotional service and not waste time in profitless philosophical speculation, fruitive activity, mystic yogic practice or severe austerity and penance.

CC Madhya-lila

CC Madhya 1.43, Purport:

There are discussions of the process of karma-tyāga (the giving of the results of karma to the Supreme Personality of Godhead), and the practices of mystic yoga and philosophical speculation, which are deprecated as simply hard labor.

CC Madhya 1.43, Purport:

There is a discussion of the differences between the mahā-bhāgavata and the ordinary devotee, the symptoms of philosophical speculation, the symptoms of self-worship, or ahaṅgrahopāsanā, the symptoms of devotional service, the symptoms of imaginary perfection, the acceptance of regulative principles, service to the spiritual master, the mahā-bhāgavata (liberated devotee) and service to him, service to Vaiṣṇavas in general, the principles of hearing, chanting, remembering and serving the lotus feet of the Lord, offenses in worship, offensive effects, prayers, engaging oneself as an eternal servant of the Lord, making friendships with the Lord and surrendering everything for His pleasure.

CC Madhya 1.43, Purport:

There are also discussions of bhakti mixed with philosophical speculation, the superexcellence of the love of the gopīs, the difference between opulent devotional service and loving devotional service, the exalted position of the residents of Gokula, the progressively exalted position of the friends of Kṛṣṇa, the gopas and the gopīs in parental love with Kṛṣṇa, and finally the superexcellence of the love of the gopīs and that of Śrīmatī Rādhārāṇī.

CC Madhya 1.198, Purport:

Su-viṣaya and ku-viṣaya both fall under the category of karma-kāṇḍa. There is another kāṇḍa (platform of activity), called jñāna-kāṇḍa, or philosophical speculation about the effects of ku-viṣaya and su-viṣaya with the intention to find out the means of deliverance from material entanglement.

CC Madhya 6.73, Purport:

One who prefers living in great mountains, even among ferocious animals, to attain the summit of philosophical speculation (understanding that the essence of this material world is useless) is called Parvata.

CC Madhya 8.68, Purport:

Devotional service by self-realization is a different subject matter. It is untouched by fruitive activity, for one surrenders the results of activities to the Lord, abandons prescribed duties and accepts the renounced order of life. Such devotional service is situated on a higher platform than that of empiric philosophical speculation with a mixture of bhakti.

CC Madhya 8.68, Purport:

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service."

CC Madhya 9.360, Purport:

Not understanding the process of disciplic succession, so-called logicians put forward the theory of pañcopāsanā, in which a person worships one of five deities—namely Viṣṇu, Śiva, Durgā, the sun-god or Ganeśa. In this conception the impersonalists imagine one of these five deities as supreme and reject the others. Such philosophical speculation, which is certainly idol worship, is not accepted by Śrī Caitanya Mahāprabhu or by Vaiṣṇavas.

CC Madhya 11.31, Purport:

The Vedas are divided into three divisions—karma-kāṇḍa, jñāna-kāṇḍa and upāsanā-kāṇḍa. These are activities dealing with fruitive work, empiric philosophical speculation and worship. There are recommendations in the Vedas for the worship of various demigods as well as Lord Viṣṇu.

"There are three ways to attain the lotus feet of the Absolute Truth, Kṛṣṇa. There is the process of philosophical speculation, the practice of mystic yoga and the execution of devotional service. Each of these has its different characteristics."

CC Madhya 24.83, Translation:

"If one follows the path of philosophical speculation, the Absolute Truth manifests Himself as impersonal Brahman, and if one follows the path of mystic yoga, He manifests Himself as the Supersoul."

CC Madhya 24.107, Translation:

"There are two kinds of worshipers on the path of philosophical speculation—one is called brahma-upāsaka, a worshiper of the impersonal Brahman, and the other is called mokṣākāṅkṣī, one who desires liberation."

CC Madhya 24.109, Translation:

"One cannot attain liberation simply through philosophical speculation devoid of devotional service. However, if one renders devotional service, he is automatically on the Brahman platform."

CC Madhya 24.111, Purport:

Śrīla Bhaktivinoda Ṭhākura has given the following summary of verses 107–111. Transcendentalists on the path of philosophical speculation can be divided into two categories—the pure worshipers of impersonal Brahman and those who wish to merge into the existence of impersonal Brahman.

CC Madhya 24.330, Purport:

As Śrīla Rūpa Gosvāmī states in the Bhakti-rasāmṛta-sindhu:

anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anāvṛtam

ānukūlyena kṛṣṇānuśīlanaṁ bhaktir uttamā

Teachings of Lord Caitanya, Chapter 1:

"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service."

CC Madhya 25.56, Purport:

All five kinds of philosophers mentioned above understand that impersonal Brahman is without material qualities, and they believe that when the Personality of Godhead appears, He is contaminated and covered by the material qualities. The technical term used is saguṇa. They speak of saguṇa Brahman and nirguṇa Brahman. For them, nirguṇa Brahman means "the impersonal Absolute Truth without any material qualities" and saguṇa Brahman means "the Absolute Truth that accepts the contamination of material qualities." More or less, this kind of philosophical speculation is called Māyāvāda philosophy.

Other Books by Srila Prabhupada

Teachings of Lord Caitanya

Worship of the impersonal Brahman and the Paramātmā is conducted by those engaged in empiric philosophical speculation and mystic yoga. However, when one develops even further in Kṛṣṇa consciousness, or spiritual understanding, he can appreciate that the Paramātmā, the Supersoul, is the eternal worshipable object, and he surrenders unto Him.

The paths of fruitive activities, speculative knowledge and meditation do not lead one to the perfectional stage, but by the process of devotional service the Lord actually becomes approachable. Therefore all Vedic literature recommends that one accept this process. In this regard, Caitanya Mahāprabhu quoted from the Lord's instructions to Uddhava in Śrīmad-Bhāgavatam:

na sādhayati māṁ yogo

na sāṅkhyaṁ dharma uddhava

na svādhyāyas tapas tyāgo

yathā bhaktir mamorjitā

"My dear Uddhava, neither philosophical speculation, nor meditational yoga, nor penances can give Me such pleasure as devotional service practiced by the living entities." (SB 11.14.20) Kṛṣṇa is dear only to the devotees, and He can only be achieved by devotional service.

In Vedic literature there are various divisions of ritualistic activities; one is karma-kāṇḍa, or purely ritualistic activities, and another is jñāna-kāṇḍa, or speculation on the Supreme Absolute Truth. What then is the purpose of the ritualistic sections of Vedic literatures, and what is the purpose of different mantras or hymns that indicate worship of various demigods? And what is the purpose of philosophical speculation on the subject of the Absolute Truth?

The philosophical sections of the Vedic hymns are intended to enable one to distinguish the Supreme Lord from māyā. After one understands the position of māyā, he can approach the Supreme Lord in pure devotional service. That is the actual purpose of philosophical speculation, and this is confirmed in Bhagavad-gītā:

bahūnāṁ janmanām ante

jñānavān māṁ prapadyate

vāsudevaḥ sarvam iti

sa mahātmā sudurlabhaḥ

"After many births and deaths, he who is actually in knowledge surrenders unto Me, knowing Me to be the cause of all causes and all that is. Such a great soul is very rare." (BG 7.19)

It can thus be seen that all Vedic rituals and different types of worship and philosophical speculation ultimately aim at Kṛṣṇa.

There are three different processes by which Kṛṣṇa can be understood: the empiric process of philosophical speculation, the process of meditation according to the mystic yoga system, and the process of Kṛṣṇa consciousness, or devotional service.

Teachings of Lord Caitanya, Chapter 10:

By the method of philosophical speculation, the impersonal Brahman feature of Kṛṣṇa is understood.

Fruitive activity, mystic meditation and philosophical speculation are not direct methods of self-realization. They are indirect because without devotional service they cannot lead to the highest perfection of self-realization. Indeed, all paths to self-realization ultimately depend on the path of devotional service.

Teachings of Lord Caitanya, Chapter 21:

No Vedic scripture should be used for indirect speculation. In addition to Śaṅkarācārya, other materialistic philosophers like Kapila, Gautama, Aṣṭāvakra and Patañjali have put forward philosophical speculation in various ways.

Teachings of Lord Caitanya, Chapter 21:

In summary it should be understood that all these materialistic philosophers have tried to avoid the Supreme Personality of Godhead by putting forward their own mentally concocted philosophies. However, Vyāsadeva, the great sage and incarnation of Godhead, has thoroughly studied all these philosophical speculations and in answer has compiled the Vedānta-sūtra, which establishes the relationship between the living entity and the Supreme Personality of Godhead and the importance of devotional service in ultimately achieving love of Godhead.

Teachings of Lord Caitanya, Chapter 23:

Śrīmad-Bhāgavatam gives information about the personal qualities of the Absolute Truth, qualities which are beyond the impersonal aspect. Topics concerning these qualities are greater than topics of impersonal philosophical speculation; consequently Śrīmad-Bhāgavatam is given higher status than the jñāna-kāṇḍa portions of the Vedas.

Nectar of Devotion

Pure devotional service should be free from the desire for any material benefit or for sense gratification, as these desires are cultivated through fruitive activities and philosophical speculation.

Generally, people are engaged in different activities to get some material profit, while most philosophers are engaged in proposing transcendental realization through volumes of word jugglery and speculation. Pure devotional service must always be free from such fruitive activities and philosophical speculations. One has to learn Kṛṣṇa consciousness, or pure devotional service, from the authorities by spontaneous loving service.

The definition of a pure devotee, as given by Rūpa Gosvāmī in Bhakti-rasāmṛta-sindhu, can be summarized thus: his service is favorable and is always in relation to Kṛṣṇa. In order to keep the purity of such Kṛṣṇa conscious activities, one must be freed from all material desires and philosophical speculation.

Any desire except for the service of the Lord is called material desire. And "philosophical speculation" refers to the sort of speculation which ultimately arrives at a conclusion of voidism or impersonalism. This conclusion is useless for a Kṛṣṇa conscious person.

Only rarely by philosophical speculation can one reach the conclusion of worshiping Vāsudeva, Kṛṣṇa. This is confirmed in the Bhagavad-gītā itself.

Nectar of Instruction 3, Purport:

The ultimate end of philosophical speculation, then, must be Kṛṣṇa, with the understanding that Kṛṣṇa is everything, the cause of all causes, and that one should therefore surrender unto Him. If this ultimate goal is reached, then philosophical advancement is favorable, but if the conclusion of philosophical speculation is voidism or impersonalism, that is not bhakti.

Nectar of Devotion 1:

In Śrīmad-Bhāgavatam, Third Canto, Twenty-ninth Chapter, verses 12 and 13, Śrīla Kapiladeva, while instructing His mother, has given the following characteristics of pure devotional service: "My dear mother, those who are My pure devotees, and who have no desire for material benefit or philosophical speculation, have their minds so much engaged in My service that they are never interested in asking Me for anything—except to be engaged in that service. They do not even beg to live in My abode with Me."

Nectar of Devotion 1:

Neither the yoga process nor philosophical speculations nor fruitive activities can save one from the seeds of sinful desires. Only by being engaged in devotional service can this be done.

Nectar of Devotion 1:

This fact is corroborated by Kṛṣṇa in the Eleventh Canto of Śrīmad-Bhāgavatam, Fourteenth Chapter, verse 20, where He says, "My dear Uddhava, you may know it from Me that the attraction I feel for devotional service rendered by My devotees is not to be attained even by the performance of mystic yoga, philosophical speculation, ritualistic sacrifices, the study of Vedānta, the practice of severe austerities or the giving of everything in charity. These are, of course, very nice activities, but they are not as attractive to Me as the transcendental loving service rendered by My devotees."

Nectar of Devotion 5:

One who has taken to bhakti, the devotional service of the Lord, need have nothing to do with karma or jñāna. It has been already explained that pure devotional service is without any tinge of karma or jñāna. Bhakti should have no tinge of philosophical speculation or ritualistic performances.

Nectar of Devotion 5:

In this connection Śrīla Rūpa Gosvāmī gives evidence from Śrīmad-Bhāgavatam, Eleventh Canto, Twenty-first Chapter, verse 2, in which Lord Kṛṣṇa says to Uddhava, "The distinction between qualification and disqualification may be made in this way: persons who are already elevated in discharging devotional service will never again take shelter of the processes of fruitive activity or philosophical speculation. If one sticks to devotional service and is conducted by regulative principles given by the authorities and ācāryas, that is the best qualification."

Nectar of Devotion 14:

In the Eleventh Canto, Twentieth Chapter, verse 31, of Śrīmad-Bhāgavatam, Kṛṣṇa says, "My dear Uddhava, for persons who are seriously engaged in My service, the cultivation of philosophical speculation and artificial renunciation are not very favorable. When a person becomes My devotee he automatically attains the fruits of the renunciation of material enjoyment, and he gets sufficient knowledge to understand the Absolute Truth." That is the test of advancement in devotional service.

Nectar of Instruction

If one strictly follows the advice given in this verse by Śrīla Rūpa Gosvāmī—namely, being enthusiastic, being confident, being patient, giving up the association of unwanted persons, following the regulative principles and remaining in the association of devotees—one is sure to advance in devotional service. In this regard Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura remarks that the cultivation of knowledge by philosophical speculation, the collection of mundane opulence by the advancement of fruitive activities, and the desire for yoga-siddhis, material perfections, are all contrary to the principles of devotional service.

Krsna, The Supreme Personality of Godhead

Krsna Book 8:

"Let me offer my respectful obeisances unto the Supreme Personality of Godhead, who is beyond the expression of consciousness, mind, work and philosophical speculation, and whose different energies produce everything manifested and unmanifested. Under His energy, bodily self and bodily possessions are conceived."

Krsna Book 8:

While mother Yaśodā was thinking in this high philosophical way, Lord Kṛṣṇa again expanded His internal energy just to bewilder her with maternal affection. Immediately mother Yaśodā forgot all philosophical speculation and accepted Kṛṣṇa as her own child. She took Him on her lap and became overwhelmed with maternal affection. She thus began to think of the Supreme Personality of Godhead, who is understood through the processes of cultivating knowledge derived from the Upaniṣads and the Vedānta-sūtra, practicing mystic yoga and studying Sāṅkhya philosophy, as her own begotten child.

Krsna Book 74:

All Vedic ritualistic ceremonies, such as the performance of sacrifices, the offering of oblations into the fire, the chanting of the Vedic hymns and the practice of mystic yoga, are meant for realizing Kṛṣṇa. Whether one follows the path of fruitive activities or the path of philosophical speculation, the ultimate destination is Kṛṣṇa; all bona fide methods of self-realization are meant for understanding Kṛṣṇa.

Krsna Book 87:

Śrī Narottama dāsa Ṭhākura has sung that persons who do not take to the devotional service of the Lord but are attracted to the process of philosophical speculation and fruitive activities drink the poisonous results of such actions.

Krsna Book 87:

Therefore by the process of self-realization or God realization through fruitive activities, philosophical speculation or mystic yoga, one cannot actually approach the supreme source of everything.

Krsna Book 89:

After attainment of knowledge, one becomes uninterested in the material world. This is not because of dry philosophical speculation. The devotees become uninterested in the material world not simply because of theoretical understanding but because of practical experience. When a devotee realizes the effect of association with the Supreme Lord, he naturally hates the association of so-called society, friendship and love.

Renunciation Through Wisdom

Renunciation Through Wisdom 2.1:

Those who know the science of Kṛṣṇa consciousness automatically know of subsidiary subjects like fruitive activity, speculative knowledge, yoga, charity, penance, austerity, and chanting mantras. Lord Kṛṣṇa confirms this in the Śrīmad-Bhāgavatam:

By executing devotional service to Me, My devotees easily acquire everything that can be attained by performing penances, fruitive activity, philosophical speculation, renunciation, yoga, charity, religiosity, and other pious acts.

Renunciation Through Wisdom 2.6:

Many spiritual stalwarts have commented upon pure devotional service. For example, Śrīla Rūpa Gosvāmī, the foremost of the great spiritual preceptors in the time of Śrī Caitanya Mahāprabhu, wrote in his Bhakti-rasāmṛta-sindhu (Bhakti-rasāmṛta-sindhu 1.1.11):

anyābhilāṣitā-śūnyaṁ

jñāna-karmādy-anāvṛtam

ānukūlyena kṛṣṇānu-

śīlanaṁ bhaktir uttama
