The will can become so strong that it controls the body, making it perfectly healthy. But, one may ask, what about death then? Death is not something foreign to will-power. Even death is caused by will-power. One thinks one does not invite one's death; indeed, one does not; but the personal will becomes feeble and the greater Will impresses this feeble will, turning it into itself. For the smaller will belongs to the greater Will. Sufis call the former Kadr and the latter Kaza. Kaza reflects upon Kadr its command, and Kadr unconsciously accepts it. On the surface a man may still want to live, but in the depth he has resigned himself to die. If man did not resign himself to death he would not die. In the depth of his being he becomes resigned to death before his life is taken away from him.
