Yogis are traditionally characterised as Indian men who don turbans, wear only the scantiest of clothing around their waists, and sit comfortably on beds of nails; conversely they’re men who can twist their bodies like pretzels into impossible positions. Krishna asserts He is the greatest yogi in the last verse of the Bhagavad-gita. Srila Prabhupada was a great yogi, but he said he didn’t have to exercise those powers. Prabhupada: I am yogi because I am taking lessons from the yogis… Dr. Patel: Yoga dharana. Prabhupaeda: Yes. Yogi, I am taking lesson from Sukadeva Gosvami. I may be fool, but I am taking lesson from the yogi. Yes. So yatra yogesvara krsna tatra srir vijayo bhutir. (From a Morning Walk, December 20, 1975, in Mumbai)
