Prabhupāda: We try to explain how God is working. So one should have brain to study things. One must have clear idea how God is person, how He is working, how this cosmic manifestation is manifested by God's energy. Kṛṣṇa says, mayā tatam idaṁ sarvaṁ jagad avyakta-mūrtinā (BG 9.4): "In My impersonal feature, everything is manifested there." Tatam idaṁ sarvam. Īśāvāsyam idaṁ sarvam (ISO 1).
So one has to apply his brain—that is intelligence—how it has become person. That is not false; that is fact. You cannot understand; your brain is teeny. That is different thing. Now you make your brain competent to understand this philosophy.
(break) . . . vijñātaṁ bhavanti. So take this philosophy nicely, understand this philosophy, and preach. You will be victorious everywhere. Because we can challenge anyone. If you know the trick, Kṛṣṇa consciousness, you can challenge. Nārāyaṇa-parāḥ sarve na kutaścana bibhyati (SB 6.17.28). One who is nārāyaṇa-parāḥ, he is never afraid of anything.
Śyāmasundara: Whenever someone challenges you, you always know the trick, what their weak point is, the weaknesses in their challenge, and you go right there. Every time.
Prabhupāda: And that is the trick of wrestling. (laughter)
Śyāmasundara: Find where they are off balance, their balance is off.
Prabhupāda: Any way. There was a wrestler, he was not very strong, but he knew the trick how to defeat the strongest man.
Śyāmasundara: There is a science of equilibrium where you can study another person. If he is off equilibrium, you can move his body in such a way to defeat him every time. Japanese art.
