Harikeśa: But happiness is a state of mind. So the child is happy . . .
Prabhupāda: Such mind is imperfect. What is this satisfaction? If mind is imperfect, so mental satisfaction is never complete satisfaction. That is also another illusion. It will be changed again. Again revolution. This is going on. So in the dialectic process, try to bring this thesis, that within this body there is the real enjoyer, and try to convince them in that way. That will be great service.
Harikeśa: You've already done it. (laughs)
Prabhupāda: I've done with a few selected men. Now it has to be spread. We have to face bigger field. Then it will be nice. Hmm? Thesis, antithesis and synthesis. This is good. This is scientific method. So, so what is that thesis? That thesis is given by Kṛṣṇa. Kṛṣṇa gave the thesis: asmin dehe, the proprietor of the body is there. Within this body . . . this is thesis.
Harikeśa: Actually, though, the . . . the thesis in Engel's philosophy would start off with the present existence, the present reality.
Prabhupāda: Eh?
Harikeśa: It starts with the present, what is now presently existing, and then the . . .
Prabhupāda: Well, presently or . . . that is another foolishness. The . . . the body and the moving active principle is eternally existing. It is not that formerly the body did not stop acting. It is dead. Study the whole history of human beings, any being—the death is always there. Then what is modern effort? Birth, death, old age, disease, they're always existing. Why do they say "modern"? This is eternal fact. Why they should say it is modern?
Harikeśa: Well, it's the present culmination of synthesis and antithesis.
