Prabhupāda: Yoga is a very broad term. Yoga means to connect with the Absolute Truth. That is yoga. Yoga means connecting link. So there are different varieties of yoga. Just like one staircase, it is the connecting link to the top floor. So that is, everywhere you can say staircase, but one who has crossed a few steps and one who has crossed a few floors, they are not on the same level.
Interviewer: I'd like to read one thing. This is evidently said by a man named Swami Śiva Premānada of New York's yoga center. He said, "If one has the time to put in about eight or ten hours a day for ten years, one might develop the power to see through a wall through meditation. I've seen people develop X-ray vision, but I've never seen the point of paying such a heavy price for it."
Prabhupāda: But I don't think it is practical that one can meditate for eight to ten hours or twelve hours.
