The question which the mystic puts to him or herself is: "Which is my being? My body? No. This body is my possession. I cannot be that which I possess." The mystic asks him or herself: "Is it my mind ?" The answer comes, "No. The mind is something I possess, it is something one witnesses. There must be a difference between the knower and the known." By this, in the end, the Sufi comes to an understanding of the illusory character of all the things one possesses. It is like a person who has a coat made: it is one's coat, it is not oneself.
