Yoko Ono: But you said about if the milk goes through a serpent's mouth it will produce poison, and, for instance, George just told us about a week ago a very interesting story about a man who had a face of Christ, and in twenty years' time he had a face of Judah. And the Catholic Church and all those churches first probably had good words, and now it's deteriorating. Now, how would you decide, really, that brāhmaṇas are always in a pure state that you speak of, that they would never turn into serpents?
Prabhupāda: That you have to become a serious student.
Yoko Ono: Well, I mean, what do you mean by serious student? Maybe everybody, all of us are serious anyway. I mean, we're born serious or born, you know, unserious.
Prabhupāda: Then you must know what is distinction between Brahman, Paramātmā, and Bhagavān, if you are serious student.
Yoko Ono: But does it depend on knowledge? I mean, the final judgement that you make?
Prabhupāda: Everything depends on knowledge. Without knowledge how can we make progress? Student means to acquire knowledge. Serious student means to acquire knowledge.
