The Mystery of the Double: Geographic Medicine

These beings of high intelligence, but of purely Mephistophelian intelligence, and with a will more akin to nature than can be said of the human will, these beings once decided out of their own will that they did not want to live in that world in which they were destined to live by the wisdom-filled gods of the higher hierarchies. They wanted to conquer the earth, and to do this they need bodies; they do not have bodies of their own. They make use of as much of the human body as they can, because the human soul cannot entirely fill up the human body.
