This is a TERRIBLE translation of the Yoga Sutras. Roach mistranslates and distorts the aphorisms of Patanjali to advance a wierd hybrid form of yoga mixed with Tibetan buddhism. As an example he translates "isvara pranidhanava" as the Master and that you must ask "her for her blessing." In his commentary, he writes that "isvara" is a living person that we must ask blessing from. "Isvara" translates, normally, to supreme god, or brahma and the entire phrase works out, according to the Monier Williams Sanskrit Dictionary as devotion to God. This wouldn't be such a bad thing until you realize that Roach's Mater is himself and he is gathering people around him in ways becoming of a sect leader. Roach has been admonished by HH the Dalai Lama and asked not to return to Dharamsala. Instead he is living out in the deserts of Arizona with a bunch of female consorts. This YS translation is a dangerous and distorted work, and should be avoided.
