Prabhupāda: The past, present, future is relative according to the duration of life and body. So Brahma's past, present, future and our past and present, future, is not the same. So time is eternal, and past, present, future is calculation of relative knowledge. That is not correct.
Jayatīrtha: Like the frog in the well.
Prabhupāda: Yes. A frog in the well is thinking, "This is the limit of water." (laughter) And if you say there is Atlantic Ocean, he cannot understand it. He will think, "What is that?" "Oh, it is very big." "How much? Is it three feet? It is four feet?" "No, no, very big." "Five feet?" "No, no, still . . ." "Six feet?" So he is calculating in that way, "Four, five, six, seven, eight, nine, ten." But Atlantic Ocean is beyond his conception. So these are all Dr. Frog's philosophy. Yes. And the so-called philosophers, they are Dr. Frog. (laughter) We consider them as Dr. Frog. Some of my students who are doctors, they are now trying to give up their job because they are understanding this is all false knowledge. Yes.
Devotee (2): Śrīla Prabhupāda, because you are presenting this knowledge so purely, then it's possible for the common man to understand this knowledge without chanting and following the four regulative principles?
Prabhupāda: That is not possible. That is not possible. Ceto-darpaṇa-mārjanam (CC Antya 20.12). You have to cleanse the mirror of your consciousness, then the reflection will be properly viewed. If you keep it dirty, then it is not possible. Therefore we require first-class men to understand this philosophy, not the fourth-class man. If you keep him fourth-class man, it is not possible.
