16 Kṛṣṇa Consciousness: the Topmost Yoga System
saying that this is the topmost  yoga  system, though at the same time it is very simple. You don't have to exercise your body over a period of weeks before you feel some power.

That is the position of the  yogī : he is not allowed to indulge in sex life. If you indulge in intoxication, if you indulge in meat-eating, and if you indulge in gambling and sporting—all nonsense—you cannot at the same time become a  yogī . I was astonished when a  yogī  came here, having advertised in India that you can be a  yogī  even though you may be addicted to drinking. This is not
