Śyāmasundara: Just like, aren't the planets in this universe the sun's energy, a product of the sun's energy?
Prabhupāda: Yes. But who produced the sun? That is Kṛṣṇa's energy. Because it is heat, and Kṛṣṇa says, bhūmir āpo 'nalo vāyuḥ (BG 7.4). Analaḥ, analaḥ, heating. "That is My energy." The sun is representation of the heating energy of Kṛṣṇa. It is not your energy. You cannot say that "The sun is made by me." But somebody must have made. And Kṛṣṇa says. So we believe therefore Kṛṣṇa. Therefore we are Kṛṣṇa-ites.
Bob: Kṛṣṇites.
Prabhupāda: Yes. Our knowledge is perfect. You cannot say... If I say that "Heat is energy of Kṛṣṇa," you cannot defy it. Because it is not your energy. Just like in your body there is some certain extent of heat. Similarly... Heat is somebody's body's energy. And who is that body? That is Kṛṣṇa. Kṛṣṇa says, "Yes, it is My energy." So my knowledge is perfect. Therefore I am the greatest scientist. Because I take the version of the greatest scientist, therefore I am greatest scientist. I may be fool personally, but because I take the knowledge from the greatest scientist, I am greatest scientist. I have no difficulty.
Bob: Excuse me?
Prabhupāda: I have no difficulty to become the greatest scientist. Because I take the knowledge from the greatest scientist.
