In his early lectures G.I. Gurdjieff described his approach to self-development as a Fourth Way. In contrast to the three eastern teachings that emphasize the development of the body, mind, or the emotions separately, Gurdjieff's exercises worked on all three at the same time to promote comprehensive and balanced inner development. Today, Gurdjieff's teachings are also sometimes referred to as "The Work", "The Gurdjieff Work", "Work on oneself" or simply "Work". Though Gurdjieff never put major significance on the term "Fourth Way" and never used the term in his writings, his pupil P.D. Ouspensky made the term and its use central to his own teaching of the Gurdjieff Ideas. After Ouspensky's death, his students published a book with that name, based on his lectures.
