Prabhupāda: There is no question of pleasure or distress. Pleasure must be there always, but it is the question of curing. Just like when you are under the treatment of an expert physician, he says that, "You shall eat like this. You shall sleep like this. You shall mate like this. You shall do like this," so it may not be pleasure, but if I want to cure myself, I have to accept the physician's direction.
It is pleasure because the physician is taking him to the healthy state of life. So as soon as he gets that he is getting healthy or he is getting out of his diseased condition, that becomes pleasurable—"Oh, yes, I am being cured. I am being cured."
So apart from that point of view, it is not the question of whether it is pleasurable or nonpleasurable, but if you want to cure yourself from the disease, you have to follow the directions. That is the process. Yes.
Man (6): But . . . but I need pleasure.
Prabhupāda: Therefore it is called tapasya. The Sanskrit word is tapasya. Tapasya means voluntarily accepting some unpleasurable thing. Voluntarily. That is called tapasya.
