The Mystery of the Double: Geographic Medicine

As the human body develops, these beings are able to enter this human body at a definite time before the human being is born, and below the threshold of our consciousness they accompany us. There is only one thing in human life that they absolutely cannot endure: they cannot endure death. Therefore they must always leave this human body, in which they have established themselves, before that body succumbs to death. This is a very harsh disappointment again and again, for just what they want to attain—to remain in human bodies beyond death—is thwarted. To do this would be a lofty achievement in the kingdom of these beings. Up until now they have not attained it.
