The Sufi is a Brahmin, for the word Brahmin means "the knower of Brahma", of God, the only Being. His religion lies in believing in no other existence save that of God, which the Brahmin calls Advaita. The Sufi has as many grades of spiritual evolution to pass through as the Yogi. There is very little difference to be found even in their practices, the difference lying chiefly in the names. No doubt the Sufi chooses a normal life in preference to that of an ascetic, yet he does not limit himself to either the former or the latter. The Sufi considers the teachings of the Avatars to be true manifestations of the divine wisdom, and he has a perfect insight into the subtle knowledge of the Vedanta.
