Bob: Can a scientist teach the science of combining acid and alkaline and this kind of science with Kṛṣṇa as its object?
Prabhupāda: How it can be?
Bob: If you... When one studies science, one finds general tendencies of nature, and these general tendencies of nature point to a controlling force.
Prabhupāda: That I was explaining the other day. Where? In Madras, or where? "Who has supplied these chemicals?"
Śyāmasundara: Ah, in Madras.
Prabhupāda: I asked one chemist that according to chemical formula, hydrogen and oxygen mixed, it becomes water. Is it not?
Bob: That's true.
Prabhupāda: Now, this vast water in the Atlantic Ocean and Pacific Ocean, how much chemicals were required?
Bob: How much?
Prabhupāda: Yes.
Bob: Oh, I don't know.
Prabhupāda: How many tons?
Bob: Many.
Prabhupāda: So who supplied it?
Bob: This was supplied by God.
Prabhupāda: Somebody must have supplied.
Bob: Yes.
Prabhupāda: So that is... You can teach like that.
Bob: And should one bother teaching that if you combine acid and alkaline...
Prabhupāda: The same thing, the same thing, that now we have to..., that... There are so many effervescence. So, who is performing it? Who is supplying the acid and alkaline? (pause)
Bob: So this comes from the same source as the water.
Prabhupāda: Um hmm. Yes. Water you cannot manufacture unless you have got hydrogen and oxygen. So here is a vast... Not only this Atlantic or Pacific, there are millions of planets, and there are millions of Atlantic and Pacific oceans. So who created this water with hydrogen and oxygen, and how it was supplied? That is our question. Somebody must have supplied; otherwise how it came to existence?
Bob: But should it also be taught how you make water from hydrogen and oxygen? The procedure of burning them together, should this also be taught? That if you burn hydrogen and oxygen together...
Prabhupāda: That is secondary.
