"The reader of Schopenhauer will be familiar with the aspect taken by Reincarnation in his philosophy. Penetrated as was the great German with Eastern thought from his study of the Upanishads, it would have been passing strange had this corner-stone of Hindu philosophy found no place in his system. Nor is Schopenhauer the only philosopher from the Intellectual and mystical German people who has accepted Reincarnation as a necessary factor in Nature... It is interesting to note that the mere idea of Reincarnation is no longer regarded in the West— at least by educated people—as absurd... Regarding it myself as, to me, a proven fact, I am concerned rather to put it forward on these pages as a probable hypothesis, throwing more light than does any other theory on the obscure problems of man's constitution, of his character, his evolution, and his destiny. Reincarnation and Karma are said by a Master [of Wisdom] to be the two doctrines of which the West stands most in. need; so it cannot be ill done for a believer in the Masters to set forth an outline, for the ordinary reader, of this central teaching of the Esoteric Philosophy."
