G.I. Gurdjieff dominated early twentieth-century esoteric thought with his unsettling system of psychological development known as the Fourth Way, inspiring 156 organisations still extant worldwide today. But much less is known about his brilliant follower, the Russian journalist/philosopher P. D. Ouspensky. This book interweaves biography with excerpts from Ouspenskys other writings to show that he had a strong mystical vision of his own.
