The Mystery of the Double: Geographic Medicine
From this you will see further that one of the most important tasks of the future will be to foster again something that has been interrupted: geographic medicine, medical geography. With Paracelsus it was torn away from the ancient atavistic wisdom. Since then it has hardly been nurtured because of materialistic views. It must take its place again, and many things must become known again if we are to come to know the connection of the illness-producing being in man with earthly geography, with all the fusions, with all the outward radiations that emerge from the earth in the various regions. It is very important for the human being to become acquainted with these things, for his life depends on it. In a very definite way he is inserted into this earthly existence by this double, and this double has his dwelling place within, within the human being himself.
