By Bayat, the initiation which a teacher gives to his pupil, a magnetism is given: the soul of the pupil is charged with a new battery. And if the pupil knows how to maintain it, how to keep it without wasting it, it will be like yeast, which never spoils and which lives for thousands of years. All the practices which are given by the teacher to guide his pupil on the spiritual path produce their particular magnetism. There is no occupation, there is no interest in the world which has so much to do with magnetism as treading the spiritual path. The power with which one progresses on the spiritual path is the power of magnetism, and the speed with which one advances depends upon the power of magnetism.
