Devotee: Well there are some theories where they think the universe was started from a big lake.
Prabhupāda: Wherefrom the lake came?
Devotee: Well, actually they say that that's not so important.
Prabhupāda: So your word is also not important. "That is not important. His word is important." Do you see the point? Whatever he'll say, that is important. So anyone can say something that is very important.
Devotee: That is to say that to understand the universe may be difficult. So therefore then they try to explain . . .
Prabhupāda: So difficult, stop. Don't talk. "Why you are talking like nonsense?" If it is difficult, accept it; don't talk. (break) Take difficult things and talk nonsense.
Devotee: Because they all have a yearning to want to know these things. They all have a yearning to want to know these things about the mystery of the universe.
Prabhupāda: Yes. But you know from the proper person. As you are very much eager to teach us, similarly, you learn; you can teach. Why do you talk nonsense without learning? You are scientist. You have to teach me. But from which scientist you have learned? So anyone can say something nonsense and become a teacher? Not teacher, but cheater.
Devotee: They have many persons that they accept as authorities.
Prabhupāda: Hah?
Devotee: They have many persons that they accept as authorities.
Prabhupāda: They have many fools. Maybe like you?
Devotee: (laughs) Yes, I admit, I am the biggest fool. But they accept some people—just like Isaac Newton. They accept him as a great authority.
Puṣṭa Kṛṣṇa: Perhaps this is a speculation—I'm not certain—but in the Bhagavad-gītā it describes that lust is also sometimes like a fire. And practically one experiences that the heat in the body, the lusty desires increases heat within the body. So is there any correlation between the fire within the body and the mode of passion?
Prabhupāda: Yes. Passion is there. Just like fire, if you fan it, it blazes more. Similarly, by passion, the fire is more powerful.
