The Mystery of the Double: Geographic Medicine

This cannot result from any sort of merely casual association; it is a holy mission laid upon humanity of the present and the future by the divine-spiritual beings who guide the world. There are certain conceptions about the super-sensible world that human beings will have to take up, because fewer and fewer super-sensible conceptions will come from the sense world. You could say that super-sensible concepts are more and more driven out of the sense world by the advance of natural science. Thus human beings would gradually be entirely shut off from the spiritual world if they received no super-sensible, spiritual concepts. They would condemn themselves after death to being completely united with the mere physical earth, to being united also with what the physical earth will become.
