Devotee: Can haṭha-yoga hinder or help Kṛṣṇa consciousness, or is it...?
Prabhupāda: Hinder. Yes. Because it is useless, simply wasting time. You cannot perform haṭha-yoga in this age. You do not follow the rules and regulations. You are simply bluffed. Do you know what is the rules and regulations of haṭha-yoga factually?
Devotee: Not actually.
Prabhupāda: Yes. You have to select a secluded place. Haṭha-yoga is not practiced in assembly of so many men. Just you go to a haṭha-yoga class. There are hundreds of members practicing, and he is collecting money, five dollars per seat. And you are thinking, "I am practicing." That is useless waste of time and money. Haṭha-yoga is not practiced in that way. You have to practice in a secluded place, alone. Do you do that?
Devotee: Yes. Not... No. I guess I don't.
Prabhupāda: It is very difficult in this age. Then you have to restrain yourself in so many things. Complete free from sex life. You have to eat under certain direction, you have to... So many things there are. These rules are not followed. Simply they have got some bodily gymnastic sitting posture. They are thinking, "I am practicing." No. That is one of the items. So all the items cannot be observed in this age. Therefore it is wasting.
