The Fourth Way enneagram is a figure published in 1949 in In Search of the Miraculous by P.D. Ouspensky, and an integral part of the Fourth Way esoteric system associated with George Gurdjieff. The term "enneagram" derives from two Greek words, ennea (nine) and gramma (something written or drawn).
The enneagram is a nine-pointed figure usually inscribed within a circle. Within the circle is a triangle connecting points 9, 3 and 6. The inscribed figure resembling a web connects the other six points in a cyclic figure 1-4-2-8-5-7. This number is derived from or corresponds to the recurring decimal .142857 = 1/7. These six points together with the point numbered 9 are said to represent the main stages of any complete process, and can be related to the notes of a musical octave, 9 being equivalent to "Doh" and 1 to "Re" etc. The points numbered 3 and 6 are said to represent "shock points" which affect the way a process develops. The internal lines between the points; that is, the three-point figure and the six-point figure, are said to show certain non-obvious connections, although here very little elucidation is offered.
The Fourth Way is an approach to self-development described by George Gurdjieff which he developed over years of travel in the East (ca. 1912). It combines what he saw as three established traditional "ways" or "schools", those of the mind, emotions and body, or of yogis, monks and fakirs respectively, and is sometimes referred to as "The Work", "Work on oneself" or "The System". The exact origins of Gurdjieff's teachings are unknown, but people have offered various sources.
The term was further used by his disciple P. D. Ouspensky in his lectures and writings. After Ouspensky's death his students published a book entitled The Fourth Way based on his lectures.
According to this system, the three traditional schools, or ways, "are permanent forms which have survived throughout history mostly unchanged, and are based on religion. Where schools of yogis, monks or fakirs exist, they are barely distinguishable from religious schools. The fourth way differs in that it is not a permanent way. It has no specific forms or institutions and comes and goes controlled by some particular laws of its own."
The Fourth Way (1957) is a book about the Fourth Way system of self-development as introduced by Greek-Armenian philosopher G.I. Gurdjieff and is a compilation of the lectures of P. D. Ouspensky at London and New York, 1921–1946, published posthumously by his students in 1957.
The term "The Fourth Way" has also come to be used as a general descriptive term for the body of ideas and teachings which Gurdjieff brought to the west from his study of eastern schools.
Ouspensky was given the task of bringing these ideas to a wider audience in an unadulterated form by Gurdjieff. The Fourth Way is considered to be the most comprehensive statement of Gurdjieff's ideas as taught by Ouspensky.
The book consists of adaptations of Ouspensky's lectures, and the accompanying question and answer sessions.
The 'Fourth Way' to which the title refers is a method of inner development - "the way of the sly man," as Gurdjieff described it. This way is to be followed under the ordinary conditions of everyday life, as opposed from the three traditional ways that call for retirement from the world: those of the fakir, the monk, and the yogi, which Gurdjieff maintained could only result in partial, unbalanced development of man's potential.
