Gurdjieff respected traditional religious practices, which he regarded as falling into three general categories or "ways" the Way of the Fakir, related to mastery of the physical body; the Way of the Monk, based on faith and feeling; and the Way of the Yogi, which focuses on development of the mind. He presented his teaching as a "Fourth Way" that integrates these three aspects into a single path of self-knowledge. The principles are laid out as a way of knowing and experiencing an awakened level of being that must be verified for oneself.
