The Sufi Order is mainly an esoteric school. There are three principal esoteric schools known in the East: the Buddhist school, the Vedantic school, and the Sufi school. The two former use asceticism as their principal means of spiritual advancement; the peculiarity of the Sufi school is that it uses humanity as its chief means to the same end. In the realization of truth the Sufi school is no different from the Vedantic or the Buddhist, but the Sufi presents truth in a different manner. It is the same frame in which Jesus Christ has given his teaching.
