Know, may God help you, that sleep is a state that moves the servant from witnessing the world of sense to witnessing the world of isthmus, and it is the most complete of the world, so there is no more complete than it. It is the origin and source of the world. It has true existence and control over all matters. It embodies meanings and restores what does not exist by itself to exist by itself, and what has no form makes it He has an image, makes the impossible possible, and disposes of matters as he pleases.
