Prabhupāda: Āhus tvāṁ ṛṣayaḥ sarve: "All the ṛṣis, great saintly persons, they have accepted You." And some of them are named: Asita, Devala, Vyāsa. They are very great authority, ṛṣis: Vyāsadeva, who has compiled the whole Vedic literature; Nārada, the spiritual master of Vyāsadeva; similarly, Asita, Devala, very, very big, big stalwart, they have accepted. So apart from all these ṛṣis, recently, within, say, thousand years, great ācāryas just like Śaṅkarācārya, Madhvācārya, Rāmānujācārya, Nimbārka, Viṣṇu Svāmī, Lord Caitanya, they have all accepted Kṛṣṇa as the Supreme. And India's Vedic culture is practically dependent on all these ācāryas. So we are follower of these ācārya, so we accept, following the footsteps of the ācārya. Ācāryavān puruṣo veda. One who has ācārya, guidance... Just like if anyone is going to be doctor of philosophy, he is guided by three ācāryas. That is the system in India. I think the same here, is it not? Anyone who is going to present some thesis, he is guided by three experienced professors, is it not?
Dr. Movebhed: Yes, more or less.
Prabhupāda: That is ācārya. So ācāryavān puruṣo veda. Without following the ācārya, if we simply theorize, that is not good. Just like the same example: if you want to put some thesis, the university regulation is that he must be guided by three experienced professor. You cannot simply put forward your thesis without being guided by the experienced professors. That thesis will not be accepted. Similarly, here Arjuna directly hears from Kṛṣṇa. So he says that "You are Parabrahma. Now I understand." Now people may say that "You are accepting Him Parabrahma. Where is your authority? You are friend. You can say Parabrahma or anything—out of love. That is not final." Therefore he quotes that... What is that? Āhus tvāṁ ṛṣayaḥ sarve: "All the big, big ṛṣis, they have accepted You." Svayaṁ caiva bravīṣi me: "And You, the Supreme Person, You are also speaking to me. And so far I am concerned, I have realized now that You are the Supreme Lord, Parabrahma." So if we follow Arjuna, then there is no difficulty. Accept Kṛṣṇa as Parabrahma. So Arjuna has heard it from Kṛṣṇa directly. This is the process. Now Kṛṣṇa says that "I accept your statement in toto."
