Prabhupāda: The bīja-pradaḥ pitā, the father, is the seed-giving person, and the mother is receiving the seed, and then she is impregnated and they develops the body. As we have got experience, the creation, the creative energy, this is going on, the same process, everywhere. So this Kāraṇābdhiśāyī Viṣṇu—we have already discussed to some extent—is the origin of this material creation. That, the scientists says, that. . . I do not know exactly what is their theory, but so far I have heard, that. . . There are so many theories. One of them is, "There was a chunk, and from that, this material world. . ." They have no idea what is material world or spiritual world. But in that way a creation took place. Can anyone say what is the theory or. . . of creation? Can any one of you say? What do they say about the creation?
Trivikrama: Their one theory is that there's a big chunk, and then from that, everything else came.
Jagadīśa: It exploded.
Rūpānuga: An explosion, a big bang.
Prabhupāda: Eh?
Rūpānuga: A big bang. An explosion.
Haṁsadūta: There were some chemicals.
Prabhupāda: So wherefrom the chunk came?
Rūpānuga: They don't tell us.
Prabhupāda: Then that is not the. . . That is their brain fag, that they are simply trying to get everything from matter. That is their material brain. But we see here that the origin is not matter. Origin is Viṣṇu, Mahā-Viṣṇu. So Mahā-Viṣṇu is the supreme soul, mahā, Mahā-Viṣṇu. So we cannot accept such nonsense theory, that chunk exploded. Where is the evidence that a chunk explodes automatically? How nonsense theory it is.
