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 Mr. Gurdjieff, concluding with his eventual decision to continue teaching this new "system" independently. Throughout the book, Ouspensky never refers to Mr. "Gurdjieff" directly, only using the single initial "G.", but it is common knowledge that this "G." was George 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 to which Ouspensky has been so arduously searching for all his life. He immediately joins Mr. 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 Mr. 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 he and Mr. Gurdjieff's eventual escape to the West, where they continued to teach Mr. 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, Mr. Gurdjieff, which he formally announced to his students in London in early 1924.
 PublicationThe book was published posthumously in 1949 by Ouspensky's students, two years after his death. Ouspensky originally titled the book simply Fragments of an Unknown Teaching, reflecting his view that Gurdjieff's system had to be "assembled" by the student himself, as well as his view that much of the original system was probably lost. However, the publisher insisted on adding the prefix In Search of The Miraculous, which became the more commonly known shortened name for the book.
Originally published at the time of George Gurdjieff's death and authorized by Gurdjieff himself, it is considered one of the best expositions of the structure of Gurdjieff's ideas, and is often used as a means of teaching Gurdjieff's system, although Ouspensky himself never endorsed its use in such a broad manner. Nevertheless, this book is by far the most quoted by current disciples of Gurdjieff as they attempt to teach his system to new students, and Mr. Gurdjieff himself even had some of his students read parts of the book as part of their studies.
The 2001 edition has a foreword by writer Marianne Williamson, in which she notes the book's reputation as being a classic, or even a primer, in the teaching of "esoteric" principles and ideas.
