This book provides entirely new source material for the Gurdjieff Work. It is an authentic transcription of talks given by Madame Ouspensky to her group at Mendham, distilled from notes taken by her pupils at the time. Students of Gurdjieff's Fourth Way know little about Madame Ouspensky's thought or teaching because she left no written body of work-although some of her sayings were recalled by Robert de Ropp in his short account of his time with her. That has been virtually the only material extant. Until now. Now, an authentic transcription of talks given by Madame Ouspensky to her group at Mendham is published here by the Gurdjieff Heritage Society. The talks, distilled from pupils notes, have been painstakingly compiled and edited by the late Dorothy Darlington who spent years with Madame and Mr Ouspensky and who had a special affinity with Madame.
