Things which seem to be apart, such as right and wrong, light and darkness, form and shadow, to the mystic appear so close that only a hair's breadth divides right and wrong. Before the mystic there opens an outlook on life, an outlook which discloses the purpose of life. The question which the mystic puts to himself is, "Which is my being? My body? No. This body is my possession. I cannot be that which I possess." He asks himself, "Is it my mind?" The answer comes, "No. The mind is something I possess, it is something I witness. There must be a difference between the knower and the known." By this method the Sufi eventually comes to an understanding of the illusory character of all he possesses. It is like a man who has a coat made: it is his coat, it is not himself.
