The fate and works of Boris Muravyov (1890-1966), one of the closest friends and associates of Gurdjieff and Uspensky, is an unknown page in the recent history of Russian religious and philosophical thought. Due to the striking depth and exhaustive clarity of the exposition of the metaphysical, psychological and practical foundations of & # 96; secret Tradition & # 96; - & # 96; esoteric Christianity & # 96; - the three-volume study of GNOSIS has no equal in modern scientific near-church literature as a truly esoteric, universal key to the knowledge of & # 96; God, man and the universe & # 96;. The first volume - EXOTERIC CYCLE - outlines in detail the general picture of the universe in the strictest interdependence of its laws, the unity of components and penetrating aspects, plans, stages of manifestation - from Absolute to atomic, from mineral to historical, from cellular to spiritual.
