In Search of the Miraculous: Fragments of an Unknown Teaching is a 1949 book by Russian philosopher P. D. Ouspensky which recounts his meeting and subsequent association with George Gurdjieff. It is widely regarded as the most comprehensive account of Gurdjieff's system of thought ever published. It is regarded as "fundamental textbook" by many modern followers of Gurdjieff's teachings, who often use it as a means of introducing new students to Gurdjieff's system of self-development.
The book is basically the author's recollection of how he learned the teaching of George Gurdjieff, a teaching which still exists today in various forms, and of which Ouspensky taught to various groups from 1921-1947; and also about his relationship with Gurdjieff, concluding with his eventual decision to continue teaching this new system independently. Throughout the book, Ouspensky never refers to Gurdjieff directly, only using the single initial "G.", but it is common knowledge that this "G." was Gurdjieff, who taught Ouspensky an ancient esoteric system of self-development commonly known as the Fourth Way.
The book begins with Ouspensky returning home to St. Petersburg from his recent excursion to the East, where he journeyed "in search of the miraculous", as he put it. He soon meets a mysterious man, a certain "G.", who has all the answers for which Ouspensky has been arduously searching all his life. He immediately joins Gurdjieff's esoteric school, and begins learning a certain system of self-development which originated in the East, allegedly during the most remote antiquity, possibly millennia before recorded history.
Ouspensky recounts his trials learning this new system, which he later refers to as the Fourth Way, often recollecting entire lectures, or parts of lectures, which Gurdjieff gave to his disciples in St. Petersburg and Moscow from 1915-1917. He describes many of his experiences, particularly concerning the "art of self-remembering", and he recounts some of the methods and various exercises which comprised Gurdjieff's system.
The book concludes with his experiences during the Bolshevik Revolution and his and Gurdjieff's eventual escape to the West, where they continued to teach Gurdjieff's system to many followers until their respective deaths in 1947 and 1949. The latter part of the book also describes the author's feelings and motives behind his eventual decision to teach the system independently, not under the direct supervision of his teacher, Gurdjieff, which he formally announced to his students in London in early 1924.
