There are certain tattva-vit, or the knower of the Absolute Truth, who understands that Absolute Truth as impersonal Brahman. And there are others, knower of the Absolute Truth, who understands the Absolute Truth as the localized Supersoul. These are called yogis. And the first-mentioned persons, they are called jñānīs. And there are other tattva-vit, or knower of the Absolute Truth, who knows the Absolute Truth as Kṛṣṇa, the Supreme Personality of Godhead. So either Brahman or Paramātmā or Kṛṣṇa the Supreme Personality of, there is no difference. The same thing, but according to the capacity of the knower, they are manifested into different phases.
We have several times discussed this point. Just like to understand the sun, somebody is studying the sun rays. He is also studying the sun and somebody is studying what is the sun disc. So he is also studying sun and somebody is trying to enter into the sun planet to see who is there. Everything is the sun. But the persons who are studying the sunshine, their grade is lower than the person who is trying to understand the sun disc. And their position is lower grade than the person who wants to enter into the sun. So the bhaktas, they are trying to see the sun-god within the sun. Just like they want to see Kṛṣṇa. In the Upaniṣad we'll find... There is a prayer that the Brahman is said, "Will You kindly push off Your glaring, dazzling glare so that I can really see You." So within the Brahmajyoti there is Kṛṣṇa. So we have to see that.
So anyway, either the Brahmavādī or Paramātmavādī or the bhakta, they are all tattva-vit. They are all transcendentalists. There is no difference. But as there are three classes in every sphere, so there are three classes in the transcendental field also. So here Bhagavad-gītā, the Lord recommends that jñāninas tattva-darśinaḥ (BG 4.34). You have to find out a person who is tattva-darśī, who has realized the Absolute Truth, either in Brahman conception or in Paramātmā conception or in Personality of Godhead conception because we have got different tastes. So the Paramātmā or the Supreme Absolute Truth is also manifested in three phases: Brahman, Paramātmā, Bhagavān. So anyway, either you select the impersonal Brahman conception of the Absolute Truth, either you select the localized supreme soul, Supersoul conception of the Absolute Truth, or you accept the highest, the Supreme Personality of Godhead Śrī Kṛṣṇa. Mattaḥ parataraṁ nānyat kiñcid asti dhanañjaya (BG 7.7). The Lord says that "This is the last phase of Absolute Truth, what I am, Kṛṣṇa."
So anyway, we have to, if we want jñāna—because the jñānamaya-yajña is recommended the highest yajña—so if we actually want jñāna, then we have to first of all find out a person who is tattva-darśī. Just like if you have to purchase gold, you must know where gold is available. If you go for purchasing gold to a grocer shop then it is hopeless. You see? It is not possible. Then you will be cheated. So at least you have to find out the person who has... That can be found. Just like by culture. That is called sacrifice, jñāna.
If you are actually in search of knowledge, Kṛṣṇa will help you, because He is helping you in every way. Īśvara. Sarvasya cāhaṁ hṛdi sanniviṣṭaḥ (BG 15.15). This we have discussed this morning. He is always with you; so He understands what kind of knowledge you are in search after. So we must be sincere, that we want to know that Absolute Truth. Then you will find out; Kṛṣṇa will help you. If you want a Brahmavādī, He will help you. If you want a Paramātmavādī, then He will help you. And if you want a devotee, that also help. So tad viddhi. You have to first of all search out a person. So Kṛṣṇa recommends that if you want knowledge then first of all... That is the process, the whole Vedic process.
In the Kaṭhopaniṣad also it is said that tad-vijñānārthaṁ gurum eva abhigacchet: "If you want to understand the transcendental science, then you have to approach to a spiritual master." And who is spiritual master? Oh, nowadays everyone wants to be spiritual master. Oh, that is also mentioned, who is spiritual master. Samit-pāṇiḥ śrotriyaṁ brahma-niṣṭham: (MU 1.2.12) "You have to approach a spiritual master who is śrotriyam and brahma-niṣṭham." Śrotriyam means who has come down from the disciplic succession, or from the Supreme. Just like we have understood in the Fourth Chapter, in the beginning of the Fourth Chapter, evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). There is a paramparā; there is disciplic succession. So one who is coming into that disciplic succession and by coming from that disciplic succession, he is firmly convinced in the Absolute, he is firmly conversant in the Absolute Truth, he is guru. Two qualifications. Tad viddhi praṇipātena paripraśnena (BG 4.34).
In Kaṭha Upaniṣad it is said tad-vijñānārthaṁ sa gurum evābhigacchet (MU 1.2.12). Abhigacchet. This is a Sanskrit grammatical injunction. Where there is the question if imperative, "you must," there vidhilin, this form of verb, is used, gacchet, gacchet. Gacchet means "You must go." You don't think that without going to a qualified, bona fide spiritual master you can have. No. That is not possible. Here also, Lord Kṛṣṇa also recommends, tad viddhi praṇipātena paripraśnena sevayā: (BG 4.34) "If you want to learn that transcendental science, then you have to find out a transcendentalist first of all." That is also recommended in Kaṭhopaniṣad.
