Prabhupāda: When you were in service? (break) They come to see me. The one psychologist and psychiatrist came to see me in Los Angeles. And many scientists come. Some of them are my disciples.
Gurudāsa: Did you ever...
Prabhupāda: Dr. Rao you know?
Indian man: I know Dr. Rao.
Prabhupāda: He is a...
Indian man: (indistinct)
Prabhupāda: Yes, he is a scientist.
Indian man: He is a scientist or something. What's he doing now about that machine?
Gurudāsa: Have you ever continued the correspondence with that heart surgeon?
Prabhupāda: No.
Gurudāsa: He was not serious?
Prabhupāda: No, he admitted. He admitted that "You know better than us."
Gurudāsa: So then why he didn't scientifically try to find out more?
Prabhupāda: Our process of presentation is different. Their process is different. But they can appreciate that we know better than them. The same example: just like we accept cow dung is pure. Why pure? Because Vedas says. The scientific way is not like that. Is not that?
Indian man: Yes.
Prabhupāda: They must prove by analysis, by chemical analysis. There is difference between the modern scientist and our process of understanding.
