Boris Mouravieff was a close associate to both Gurdjieff and Ouspensky. Mouravieff's main work, a trilogy, is titled Gnosis: Study and Commentaries on the Esoteric Tradition of Eastern Orthodoxy. It is divided into three cycles, one for each volume. Book One - Exoteric Cycle, Book Two - Mesoteric Cycle, and Book Three - Esoteric Cycle.
Mouravieff weaves Gurdjieff's Fourth Way with Ouspensky's cosmology into a synthesis with what he calls the "Royal Road", basically a lost Christian esoteric tradition. The books are very full of theory and practice. Keep in mind Gurdjieff got his start and inspiration by coming across some Orthodox holy men in Armenia, so in a way it is interesting that Mouravieff is picking up where Gurdjieff started. As I work within a more Christian Hermetic approach, I have found the books to be useful in supplementing aspects of my own practice.
On a side note Gurdjieff was one hell of a guy. He is definitely underappreciated in the occult community. I never gave him much thought until I came across mention of him from Dr. Hyatt in his Radical Undoing work.
