SB Canto 1

The Vedic system of acquiring knowledge is the deductive process. The Vedic knowledge is received perfectly by disciplic succession from authorities.

SB 1.9.18, Purport:

The Vedic system of acquiring knowledge is the deductive process. The Vedic knowledge is received perfectly by disciplic succession from authorities. Such knowledge is never dogmatic, as ill conceived by less intelligent persons. The mother is the authority to verify the identity of the father. She is the authority for such confidential knowledge. Therefore, authority is not dogmatic. In the Bhagavad-gītā this truth is confirmed in the Fourth Chapter (BG 4.2), and the perfect system of learning is to receive it from authority. The very same system is accepted universally as truth, but only the false arguer speaks against it. For example, modern spacecraft fly in the sky, and when scientists say that they travel to the other side of the moon, men believe these stories blindly because they have accepted the modern scientists as authorities. The authorities speak, and the people in general believe them. But in the case of Vedic truths, they have been taught not to believe. Even if they accept them they give a different interpretation. Each and every man wants a direct perception of Vedic knowledge, but foolishly they deny it. This means that the misguided man can believe one authority, the scientist, but will reject the authority of the Vedas. The result is that people have degenerated.

SB Canto 2

Because human life is a combination of matter and spirit soul, the whole process of Vedic knowledge is directed at liberating the spirit soul from the contamination of matter.

SB 2.1.3, Purport:

The present human civilization is primarily based on the principles of sleeping and sex indulgence at night and earning money in the day and spending the same for family maintenance. Such a form of human civilization is condemned by the Bhāgavata school.

Because human life is a combination of matter and spirit soul, the whole process of Vedic knowledge is directed at liberating the spirit soul from the contamination of matter. The knowledge concerning this is called ātma-tattva. Those men who are too materialistic are unaware of this knowledge and are more inclined to economic development for material enjoyment. Such materialistic men are called karmīs, or fruitive laborers, and they are allowed regulated economic development or association of woman for sex indulgence. Those who are above the karmīs, that is, the jñānīs, yogīs and devotees, are strictly prohibited from sex indulgence. The karmīs are more or less devoid of ātma-tattva knowledge, and as such, their life is spent without spiritual profit. The human life is not meant for hard labor for economic development, nor is it meant for sex indulgence like that of the dogs and hogs. It is specially meant for making a solution to the problems of material life and the miseries thereof.

As the decision of the supreme court of a state is final, similarly the judgment of Brahmājī, the supreme authority in the universe, is final in the Vedic process of acquiring knowledge.

SB 2.5.11, Purport:

Lord Brahmājī said to Nārada that his impression that Brahmā was not the supreme authority in the creation was correct. Sometimes less intelligent men have the foolish impression that Brahmā is the cause of all causes. But Nārada wanted to clear the matter by the statements of Brahmājī, the supreme authority in the universe. As the decision of the supreme court of a state is final, similarly the judgment of Brahmājī, the supreme authority in the universe, is final in the Vedic process of acquiring knowledge. As we have already affirmed in the previous verse, Nāradajī was a liberated soul; therefore, he was not one of the less intelligent men who accept a false god or gods in their own ways. He represented himself as less intelligent and yet intelligently presented a doubt to be cleared by the supreme authority so that the uninformed might take note of it and be rightly informed about the intricacies of the creation and the creator.

Bhagavad-gita As It Is Lectures

With all these defects, we cannot accept anyone's knowledge. This is Vedic process. This is called paramparā system, disciplic succession. We receive knowledge perfectly from the Supreme Bhagavān.

Lecture on BG 2.2 -- London, August 3, 1973:

Those who are in this material world, they have got four defects: they commit mistake, they are illusioned, and their senses are imperfect, bhrama, pramāda, vipralipsā, and they're cheaters. Because... Just like modern-day scientists and philosophers, they propogate so many branches of knowledge, but when, on the crucial point, they are caught, they say, "I do not know perfectly. I do not know perfectly. We are trying to know. In future, we shall tell you the perfect." But if you are not in perfect knowledge, why should you take the post of a teacher? If your knowledge is imperfect, then whatever you speak, that is imperfect. Therefore with imperfect knowledge, why you should become a teacher? That is cheating. That is cheating. Therefore purposefully Vyāsadeva is writing, sri-bhagavān uvāca, where there is no cheating, no imperfection, no illusion, no mistake. Four things. No mistake, no illusion, no cheating and no imperfection. This is Bhagavān. Why we are taking Bhagavad-gītā so seriously? There are so many other books we can read, so many theories, so many philosophers, big, big philosophers. But we cannot take them because they are defective. The author is sure to commit mistake. He is illusioned. Because his senses are not perfect, therefore imperfection.

So with all these defects, we cannot accept anyone's knowledge. This is Vedic process. This is called paramparā system, disciplic succession. We receive knowledge perfectly from the Supreme Bhagavān.

Our process of knowledge, Vedic process of knowledge: tad-vijñānārthaṁ sa gurum eva abhigacchet. Their knowledge should be taken from the authority. Do not manufacture knowledge. Because how you can manufacture perfect knowledge? You are imperfect.

Lecture on BG 2.13 -- Hyderabad, November 19, 1972:

Here is the beginning of education, real education. What Kṛṣṇa says. I have already explained that... (aside:) Why they are talking? I have already explained that our process of accepting knowledge is the paramparā system. Avaroha-panthā. There are two ways of acquiring knowledge, āroha-panthā and avaroha-panthā. Knowledge coming from the authorities, that is perfect knowledge. And knowledge acquired by experimental knowledge, that is not perfect. Because we are imperfect. Suppose a big professor, just like that Russian Professor Kotovsky, they are trying to understand things by so-called inductive process, or āroha-panthā, going up by one's speculation, by speculative method. But our process of knowledge, Vedic process of knowledge: tad-vijñānārthaṁ sa gurum eva abhigacchet (MU 1.2.12). Their knowledge should be taken from the authority. Do not manufacture knowledge. Because how you can manufacture perfect knowledge? You are imperfect. Your senses are imperfect. You are defective in four ways. You are... To err is human. You must commit mistake. You must be illusioned. Your senses are imperfect, and you have got a cheating propensity. These four defects are there. Those who are not liberated, mukta-puruṣa, they have got four defects. What is that? He must commit mistake. Just like we can give you instance: Our Mahatma Gandhi, he was so great personality, but he also committed so many mistakes. Even on the day of his death, it is heard that he was forbidden not to go the meeting. The other persons, they scented some danger, but he forcibly went there and he was killed. So mistake, committing mistake. To err is human. That is not fault. That is our habit. We commit mistake. And we also, we are illusioned. Illusioned. Just like I am not this body. I am spirit soul. Ahaṁ brahmāsmi. But we are giving identification with this body. "I am Indian," "I am American," "I am brāhmaṇa," "I am śūdra." So this is illusion. So to commit mistake and to become illusioned and cheating propensity. Actually, I do not know things as they are, still, I am writing books. To educate people. Big, big scholars, they have no clear thought, clear understanding; still they write books. Even Darwin's theory. He's proposing, "Perhaps; it may be," and he's writing a big book, anthropology. And people are taking knowledge from that book. So if his knowledge based on "Perhaps; maybe," what is the value of that knowledge?

So many things there are that direct perception is not possible. Therefore in the Vedic process of knowledge the authority has been accepted as the perfect source of knowledge.

Lecture on BG 4.3-6 -- New York, July 18, 1966:

So there is one very good example. Now, if somebody wants to know, "Who is my father? Who is my father?" And how he can know? There is no possibility of direct perception to know the father. It is not possible. Then who is the authority? The mother is the authority. When the mother says, "My dear son, here is your father," we have to accept it. If you say, "No, I don't believe you, mother," then you have no other source of knowledge who is your father. You have no other alternative; excepting the authority of your mother, you cannot know who is your father. Because he was your father before your birth, so how you can have direct perception? It is not possible. So many things there are that direct perception is not possible. Therefore in the Vedic process of knowledge the authority has been accepted as the perfect source of knowledge.

There are two kinds of processes to receive knowledge. The Vedic process says, avaroha-panthā, descending process. And the material process is āroha-panthā, ascending process, research.

Lecture on BG 4.5 -- Montreal, June 10, 1968:

Therefore there are two kinds of processes to receive knowledge. The Vedic process says, avaroha-panthā, descending process. And the material process is āroha-panthā, ascending process, research. This is āroha-panthā, find out whether this, what is this, what is this, neti, neti, neti, neti, analysis, dissection, and so many. This is called āroha-panthā. Trying to ascend by dint of one's material knowledge. Then spiritual knowledge, you cannot have perfect knowledge... Why spiritual knowledge? Even material knowledge. Now there are so many attempts to go to the moon planet. They are trying to go there by so many ascending processes, sputnik, airplanes, and so many things. Still, we do not know what is this planet.

But you read Bhagavad-gītā or Śrīmad-Bhāgavatam, you understand immediately what is this moon planet. It is said in the Bhagavad-gītā nakṣatrāṇām ahaṁ śaśī. Śaśī means this moon planet. You immediately understand that this moon planet is one of the stars. Just like the constitutional position of other stars, you understand the moon is like that. And they are searching after whether in the moon planet there is life or not, there is living condition or not. But you open Śrīmad-Bhāgavatam, you'll find the description of the moon planet, how they are living, what is the constitution of the living creatures there. The soma-rasa, you have heard this word. The soma-rasa is beverage in the moon planet. So everything is there. And who can go there, and how one can go there. So this is perfect knowledge, to hear from the authorities.

Ascending process is not recommended in the Vedic process of knowledge. Vedic way of receiving knowledge—by aural reception, by submissive aural reception from the spiritual master to the student. This is the way.

Lecture on BG 9.15 -- New York, December 1, 1966:

So that is the process, hearing. You can hear at any place. Even in the warfield, you can hear from the authoritative source. So that was the process of acquiring knowledge, hearing. Hearing means receiving the knowledge, not manufacturing. There are two process of knowledge. There are some persons who think, "Oh, why shall I hear from him? Oh, I can think. I can speculate. I can manufacture something new of my own group." These are nonsense. This is not Vedic process. Vedic process is hearing, ascending process, er, not..., descending process. There are two processes of knowledge: ascending and descending. Ascending means trying to go high by your strength, and descending means the pure knowledge which comes from up, you receive it. Inductive and deductive process.

So ascending process is not recommended in the Vedic process of knowledge. Vedic way of receiving knowledge—by aural reception, by submissive aural reception from the spiritual master to the student. This is the way. It is coming.

Srimad-Bhagavatam Lectures

We cannot understand in our present state what is that spirit soul. We have to understand it by the śruti process, Vedic knowledge. That is real understanding.

Lecture on SB 5.5.30 -- Vrndavana, November 17, 1976:

So what is that thing? It is definition by negation. We cannot understand in our present state what is that spirit soul. Although we can perceive that there is something—in the absence of that something, this body is nothing but a lump of matter. That we get experience every day. But we cannot see what is that. Therefore atheist class or the persons with poor fund of knowledge, they deny the existence. They cannot see. But they cannot answer that why the body is no more working, what is that thing which is absent? They have tried to explain in so many ways how that something... But they could not practically explain. We have to understand it by the śruti process, Vedic knowledge. That is real understanding. And understanding from the right person, Kṛṣṇa or His representative. And it has to be understood simply by hearing. There is no other process.

Our process of Vedic knowledge is how to surrender, not that I hear and I reject it. That is not the way.

Lecture on SB 6.1.9 -- Honolulu, May 10, 1976:

So here the Bhāgavata-kathā, that is transcendental knowledge. So Parīkṣit Mahārāja has approached the right person, Śukadeva Gosvāmī. Why? Because he is the disciple and son of Vyāsadeva. So this is paramparā. One should learn from the right person, that is perfect knowledge. We are sticking to Kṛṣṇa consciousness movement because to receive perfect knowledge. If we change, if we become so rascal that "What has spoken in the Vedic literature, there is beyond, something," then we are rascal. There is no beyond. This is perfect knowledge. So how to take perfect knowledge? Tad viddhi. First of all you try to learn. Tad viddhi. How to learn? Where to learn? Praṇipātena, fully surrendered. If you find somebody that he is somebody important where you can surrender fully, from him... Tad viddhi praṇipāta... This is. Our process of Vedic knowledge is how to surrender, not that I hear and I reject it. That is not the way. That is another rascaldom. First of all find out the person where you can surrender.

Nectar of Devotion Lectures

Our process of Vedic knowledge is that we get knowledge from the superior just like Brahmā, Lord Brahmā. He's the first, original creature, within this universe. And he got knowledge from God, Kṛṣṇa, the Absolute.

The Nectar of Devotion -- Bombay, December 28, 1972:

Guest: For material men like us it is not possible to accept the Vedas. Because we do not know. I do not see. It may not be there. But all we can say that we are still in the dark or ignorant about the...

Prabhupāda: But we have to take knowledge from superior authority. I am always not in knowledge. That is my position. But we take knowledge from superior authority. So we are taking knowledge from Kṛṣṇa, the most superior authority. (break) ...our Vedic system. It is advised, tad vijñānārthaṁ sa gurum eva abhigacchet (MU 1.2.12). That is the system. Just like you are a medical man. To acquire your knowledge, you had to accept the medical college, the professors. So this is natural. If we want to know something which is not, or which is unknown to me, then we have to accept a guru, a superior man. Guru means superior man. Tad vijñānārthaṁ sa gurum eva abhigacchet. Guru means "heavy," or "superior." That is the law. So our process of Vedic knowledge is that we get knowledge from the superior just like Brahmā, Lord Brahmā. He's the first, original creature, within this universe. And he got knowledge from God, Kṛṣṇa, the Absolute. The Vedas means the knowledge which he heard... Tene brahma hṛdā ādi-kavaye. So there is sampradāya. Brahmā imparted this knowledge to Nārada. Nārada imparted this knowledge to Vyāsadeva. Evaṁ paramparā. That, this is our process of knowledge. We get knowledge from the superior. Everyone gets knowledge from the superior. Nobody gets knowledge automatically. That is not possible. So things which are beyond the perception of our senses, how we can get that knowledge? By our mental speculation, it is not, never perfect.

We cannot expect perfect knowledge from the imperfect person. So our process of knowledge is different. Our Vedic process of knowledge is that one has to accept a guru, a spiritual master, who has received knowledge from another perfect spiritual master.

The Nectar of Devotion -- Vrndavana, November 5, 1972:

So the best knowledge, He's giving, Kṛṣṇa Himself: Bhagavad-gītā. He's coming personally to give knowledge. But we are so unfortunate, we are not accepting the knowledge given by Kṛṣṇa. We are hankering after some other knowledge given by some defective human being. A human being cannot give us any perfect knowledge. Therefore all the scientists' statements, all the philosophers' statements, they are simply theories; they are not fact. Because the knowledge is not perfect. Perfect knowledge can be had from one who is not defective. Defective means generally a conditioned soul has four defects: he commits mistake, he is illusioned, he has got a cheating propensity, and his senses are imperfect. The senses, we are acquiring knowledge through our senses, and if our senses are imperfect, how we can acquire perfect knowledge? Just like we are trying to see the planetary system through microscope or binocular, telescope, but the telescope machine is manufactured by a person who is, whose senses are defective. So through the telescope, how you can have perfect knowledge? Therefore one astronomer is placing some theory. After some years, that is made null and void; another theory is presented. Because everyone's knowledge is imperfect. So we cannot expect perfect knowledge from the imperfect person. So our process of knowledge is different. Our pro..., Vedic process of knowledge is,

tad-vijñānārthaṁ sa gurum eva abhigacchet

samit-pāṇiḥ śrotriyaṁ brahma-niṣṭham

(MU 1.2.12)

One has to accept a guru, a spiritual master, who has received knowledge from another perfect spiritual master. Just like Kṛṣṇa is the origin, perfect spiritual master, guru. So Kṛṣṇa, what Kṛṣṇa said, was realized by Arjuna, directly. Therefore if we receive knowledge from Arjuna or his disciplic succession, then our knowledge is perfect.

Sri Isopanisad Lectures

Just like the Bhagavad-gītā, the old thing is being explained again by Kṛṣṇa to Arjuna. So we have no, nothing to research. Everything is there. Simply we have to hear from a person who is dhīra, who is not agitated by the six kinds of agitating agents. That is the process of Vedic knowledge.

Sri Isopanisad, Mantra 10 -- Los Angeles, May 15, 1970:

So you have to hear from such person, dhīra. Here it is stated, iti śuśruma dhīrāṇām. Dhīrāṇām. Then your knowledge will be perfect. If you hear from adhīrāṇām, those who are not controlled, then it is useless knowledge. But here it is in the Vedic version of Īśopaniṣad, iti śuśruma dhīrāṇāṁ ye nas tad vicacakṣire. So the student has approached the spiritual master and he says that "We have heard like this. Now it may be kindly explained." So teacher or the spiritual master is not inventing something. The same old thing. Just like the Bhagavad-gītā, the old thing is being explained again by Kṛṣṇa to Arjuna. So we have no, nothing to research. Everything is there. Simply we have to hear from a person who is dhīra, who is not agitated by the six kinds of agitating agents. That is the process of Vedic knowledge.

tad viddhi praṇipātena

paripraśnena sevayā

upadekṣyanti (te jñānaṁ)

jñāninas tattva-darśinaḥ

(BG 4.34)

So always remember that we have to learn from a person who is dhīra, who has control over these agitating agents.

In this way Brahmā distributed this Vedic knowledge, some to the sons, some to the... Vyāsadeva also, he distributed knowledge, some to his sons, some to his disciples. That is explained in the Śrīmad-Bhāgavatam. So that is the process of disseminating Vedic knowledge.

710708 - Lecture ISO - Los Angeles:

Formerly the spiritual master, the disciplic succession, there are two ways. One is called śaukra and another is called sautra. Śaukra means succession from the seminal. Just like son. Son is born by the semina, and the disciple is born by Vedic knowledge. So the one familywise is called śaukra. Śukra means semina, coming from the śukra, and the other is sautra, by hearing. So spiritual master... In India still there are gotras. Gotras means coming from that great sage. Just like our family belongs to the Gautama gotra. Gautama Ṛṣi, from him the familywise gotra, and similarly disciplic succession is also gotra. There is no difference between putra and chatra. Putra means son, and chatra means disciple. Cāṇakya Paṇḍita said, putrāṁś ca śiṣyāṁś ca; they are equally treated. Both of them equally eligible for hereditary rites from the person, either he is son or disciple. So Brahmā distributed knowledge to some... Practically everyone was his son because he was the first living creature. So later on, disciples also, son's son. So in this way Brahmā distributed this Vedic knowledge, some to the sons, some to the... Vyāsadeva also, he distributed knowledge, some to his sons, some to his disciples. That is explained in the Śrīmad-Bhāgavatam. So that is the process of disseminating Vedic knowledge.

Festival Lectures

All Vedic process of knowledge is taking from the authority. And it comes down through disciplic succession.

Sri Vyasa-puja -- New Vrindaban, September 2, 1972:

So we are not interested now about calculation the perfect knowledge. This perfect knowledge comes from God, or Kṛṣṇa, and it is distributed by paramparā system, by disciplic succession. The example is just there, a mango tree. On the top of the mango tree there is a very ripened fruit, and that fruit has to be tasted. So if I drop the fruit from up, it will be lost. Therefore it is handed over, after one, after one, after... Then it comes down. So all Vedic process of knowledge is taking from the authority. And it comes down through disciplic succession. Just like I have already explained, Kṛṣṇa gives the knowledge, perfect knowledge, to Brahmā, and Brahmā gives the knowledge to Nārada. Nārada gives the knowledge to Vyāsa. Vyāsa gives the knowledge to Madhvācārya. Madhvācārya gives the knowledge to his disciplic succession, later on, to Mādhavendra Purī. Mādhavendra Purī gives that knowledge to Īśvara Purī. Īśvara Purī gives that knowledge to Caitanya Mahāprabhu, Lord Caitanya. He delivers that knowledge to His immediate disciples, six Gosvāmīs. The six Gosvāmīs delivers the knowledge to Śrīnivāsa Ācārya, Jīva Gosvāmī. Then Kavirāja Gosvāmī, then Viśvanātha Cakravartī, then Jagannātha dāsa Bābājī, then Bhaktivinoda Ṭhākura, then Gaura Kiśora dāsa Bābājī Mahārāja, then my spiritual master, Bhaktisiddhānta Sarasvatī. Then we are distributing the same knowledge.

Tathā dehāntara prāptiḥ. This is Vedic knowledge, this evolutionary process. It is not Darwin's theory.

His Divine Grace Srila Bhaktisiddhanta Sarasvati Gosvami Prabhupada's Disappearance Day, Lecture -- Hyderabad, December 10, 1976:

So actually we are in a very precarious condition, the modern civilization, I mean to say, manipulated by the Western people. It is a soul-killing civilization, this civilization. By nature the chance is given after many, many evolutionary process. Jalajā nava lakṣāṇi sthāvarā lakṣā viṁśati. The evolutionary theory is there in the Padma Purāṇa. It is not Darwin's theory. Darwin stolen it from Padma Purāṇa, and he presented in a distorted way of his own imagination. Otherwise the Darwin's theory is not the original. The theory... It is not theory-fact. Jīva-jātiṣu. It is wandering within the cycle of jīva-jāti, different species of life. Tathā dehāntara prāptiḥ (BG 2.13). This is Vedic knowledge, this evolutionary process. It is not Darwin's theory.

Philosophy Discussions

To know through authorities, that is knowing. That is real knowing. That is the process of Vedic knowledge: to know through the authorities.

Philosophy Discussion on Ludwig Wittgenstein:

Śyāmasundara: So our ultimate verification does not rest with our senses but with the authoritative...

Prabhupāda: Yes. Authoritative knowledge, that is real seeing. That is real seeing. Just like we have not seen Kṛṣṇa, take for example. Then all we are fools and rascals, that we are after Kṛṣṇa? People may say that "You have not seen Kṛṣṇa. Why you are after so much, Kṛṣṇa?" They can say. But then you are all set of fools. Does it mean that we are all set of fools? Then how we have seen Kṛṣṇa?

Śyāmasundara: Wittgenstein, in that respect he answers that these metaphysical or mystical ideas, even though they are not expressed in words, can be felt or appreciated without knowing whether it is true.

Prabhupāda: No. That is knowing. To know through authorities, that is knowing. That is real knowing. That is the process of Vedic knowledge: to know through the authorities. The same example: if somebody is asking, "Who is my father?" then he has to know through the authority of mother; otherwise there is no other way. So therefore to know through authority is perfect knowledge.

1972 Conversations and Morning Walks

Just like when you become serious of studying any subject matter, you find out some college, some institution. You cannot purchase the books and read at home and become expert engineer, expert, no. That is not the process. Therefore the Vedic knowledge is called śruti. We have to hear by paramparā system.

Conversation with Bajaj and Bhusan -- September 11, 1972, Arlington, Texas, At Their Home:

Guest (2): And can one not directly surrender to Kṛṣṇa through his own feelings and heart and...?

Prabhupāda: No. No, that is not the process. Caitanya Mahāprabhu teaches, gopī-bhartuḥ pada-kamalayor dāsa-dāsānudāsaḥ (CC Madhya 13.80). He wants to become the servant of the servant of the servant of the servant of the servant of Kṛṣṇa. That is the process. If you want to know Kṛṣṇa directly it is not possible. Otherwise why Kṛṣṇa says, tad viddhi praṇipātena paripraśnena sevayā (BG 4.34)? And how you can approach Kṛṣṇa?

Guest (2): Chanting His names, surrendering to Him, feeling love for Him, doing service. Is that not or would that not take one person to...?

Prabhupāda: No, that is not the way. Kṛṣṇa says, evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). You have to accept the paramparā, disciplic succession. That is a challenge, that "I don't want to surrender anyone."

Guest (2): No, not challenge... I'm not saying... I mean, I'm not...

Prabhupāda: No, it is not possible. Kṛṣṇa accepted Himself a guru. Lord Caitanya Mahāprabhu accepted a guru. They are God Himself. So how you can accept: "I can approach Kṛṣṇa without guru"? Guru-kṛṣṇa-kṛpā. Kṛṣṇa... When actually you want Kṛṣṇa seriously—you do not know who is guru—then Kṛṣṇa will give you a guru. Just like Dhruva Mahārāja. He was advised by his mother that "If you go to the forest you can see God." So he went there. But when he was very serious, then Kṛṣṇa sent him Nārada Muni. So if you are actually serious about Kṛṣṇa, then Kṛṣṇa will send you some of His representative and he will take charge of you. That is the process. If you do not find a guru, that means Kṛṣṇa is not yet pleased, either you are not serious. Just like when you become serious of studying any subject matter, you find out some college, some institution. You cannot purchase the books and read at home and become expert engineer, expert, no. That is not the process. Therefore the Vedic knowledge is called śruti. Śrotriyaṁ brahma-niṣṭham. Tad-vijñānārthaṁ sa gurum evābhigacchet, śrotriyaṁ brahma-niṣṭham (MU 1.2.12). So we have to hear by paramparā system. You attend the lectures of a professor because he has heard. He has listened the same instruction from his professor. You don't go to a professor who has never gone to school and college. Do you go there? So this knowledge... As material knowledge is received by paramparā, similarly, spiritual knowledge is received also by paramparā.

1973 Conversations and Morning Walks

For perfect knowledge, we have to take it from the perfect authority, not by our speculative intellectual gymnasium. No, that will not help. Because our intellectual jurisdiction is very limited. That is Vedic process. Vedic process is not to acquire knowledge by ascending process, inductive process. Vedic knowledge is to receive knowledge by descending process, knowledge coming from authority.

Room Conversation with Latin Professor -- December 9, 1973, Los Angeles:

Prabhupāda: Here, from the material platform, our source of knowledge is direct perception. That is crude, pratyakṣa. It is called pratyakṣa. That is crude knowledge, direct perception. Just like I am seeing the sun. I am getting some idea of the sun, but that is not the perfect idea, although I am seeing it daily. I am seeing just like a disc, but it is very, very big. So my direct perception cannot give me perfect knowledge. The first... Besides that, at our present stage, material condition, we are imperfect because we commit mistake. By direct seeing the sun, I am thinking that it is just like a disc. Then we are illusioned. We, sometimes we accept something for something. Then, with this imperfect knowledge, we try to become teacher. That is cheating. And at the end, our senses are imperfect. So with so many imperfectness, how we can get perfect knowledge? What is your answer?

Professor: I have no answer.

Prabhupāda: Yes. Therefore, our speculative knowledge, intellectual platform, is not helpful. We must receive knowledge from superior source, perfect source. That knowledge is perfect. Just like we give, generally this example, that to find out who is my father, my search out, research, will not help me, but if my mother says, "Here is your father," that is perfect knowledge because she's authority. Therefore, for perfect knowledge, we have to take it from the perfect authority, not by our speculative intellectual gymnasium. No, that will not help. Because our intellectual jurisdiction is very limited. That is Vedic process. Vedic process is not to acquire knowledge by ascending process, inductive process. Vedic knowledge is to receive knowledge by descending process, knowledge coming from authority. That, that you will find in the Bhagavad-gītā, Fourth Chapter: evaṁ paramparā prāptam imaṁ rājarṣayo viduḥ (BG 4.2). Knowledge has to be received... Just like a child receives knowledge... He is inquisitive: "Mother, what is this? Father, what is this?" And mother informs him, "My dear child, this is is. This is this." So he is acquiring knowledge by descending process. And if the child wants to get knowledge independently, that is not knowledge. He'll touch the fire. Mother: "Don't touch, don't touch, my dear child!" But he does not know. He's thinking the fire as something eatable. So by the Vedic process, this experimental knowledge is no useful. Yes. The Vedic injunction is tad-vijñānārthaṁ sa gurum evābhigacchet: (MU 1.2.12) "In order to receive perfect knowledge, you must have approach the guru." Guru means who has the perfect knowledge. So you cannot independently get perfect knowledge, intellectual. That will remain always imperfect. So intellectually, how you can conceive about God, who is unlimited, beyond your sense perception? We cannot know even ordinary material things, how great the sun is, how this universe is. We have imperfect knowledge. So our process is to receive knowledge from the perfect. Therefore, we are receiving knowledge from Kṛṣṇa, the supreme perfect.
