Fourth Way esotericism, Gurdjieffian mysticism

P. D. Ouspensky

1878 – 1947

Pyotr Demyanovich Ouspensky (1878–1947) was a Russian journalist, mathematician, and esotericist who became the principal expositor of G. I. Gurdjieff's Fourth Way system, documenting his decade under Gurdjieff's instruction in the landmark In Search of the Miraculous (published posthumously, 1949). After separating from Gurdjieff in 1924, Ouspensky taught the system independently in England and the United States; his earlier Tertium Organum (1912) explored the fourth dimension as a key to mystical consciousness.
