Book excerpt: Eastern Psychology has given the West a clue to certain mysteries previously baffling as, for example, in the departments of: 1. Mesmerism and hypnotism. 2. The supposed posthumous relations of the disincarnate entity with the living. 3. The nature and relations of Force and Matter capable of practical verification by whomsoever may learn and follow out the experimental methods of the Oriental Schools of Occult science. Eastern Occult Science and its complementary philosophy throws light upon some of the deepest problems of man and nature. But Occultism is colourless, cosmopolitan, unsectarian, sexless, unworldly, altruistic.
