II. The Transformation of Earthly Forces into Clairvoyant Faculties

The high degree of co-ordination in the brain-substance of the average man nowadays was not present in the men of ancient Greece, about the sixth or fifth century B.C. Human nature changes in this respect more rapidly than is supposed. In the Greeks of the prehistoric epoch—the tenth, eleventh, twelfth centuries B.C.—there arose quite naturally at a certain age the clairvoyance that can now again be given expression as Spiritual Science, And the forces which to this day remain over from the elaboration of the grey substance of the brain must be exercised in the way described in order to survey with clarity and definition what is presented in my book Occult Science.
