The visible and the invisible world are lost in the soul. The soul is hidden from and lost in the body and the body from the soul. When you come out of this maze, you will find the proper place for a man. If you will reach this particular place, you will acquire in a single moment the knowledge of hundreds of mysteries, but woe to you, if you lag behind in this road! You will lose yourself totally in the path of grief. Do not sleep in the night and do not eat anything during the day. Then, perhaps, the desire for this quest will be kindled in you. Seek until you lose yourself in the search and you lose even the idea of the search!
