Some claim that telepathy and clairvoyance and pre-vision of the future are high-level powers characteristic of the upper reaches. I am not in a position to judge whether such powers exist or not, though on the whole I incline with much hesitation to believe that in some form or other they do. But I cannot see anything particularly lofty about them. They may be consequences of high development, but in themselves they are merely strange modes of perceiving events of commonplace order.
