Stephen Flowers has a chapter on Gurdjieff in his "Lords of the Left Hand Path." Does G. belong there? True he makes some LHP noises. But this is all with an eye to eventually reintegrating the now-harmonized Man (sans scare quotes) into what is a recognizably RHP cosmos. The "perfect egoist" finally becomes a "helper to God." Nimrod de Rosario ("Secret History of the Thule Gesellschaft") hints that Gurdjieff was indeed in on what's afoot in the cosmos, but as a "black siddha"---i.e., one serving the dark purposes of an ultimately dystopic RHP. In other words that his Fourth Way was a false flag op subverting the real LHP.
Any thoughts on the matter?
I'm generally resistant to the kinds of categorisation that says "this is Left Hand Path", "this is Right Hand Path". Sometimes things can be complicated and actions which may appear one way, may serve an entirely different purpose in the magician's psyche. For example, the many Satanists who are dogmatically committed to socially (even government) approved programming are, according to my definition, entirely Right Hand Path. A magician invoking Jesus as a way of rising from their own death... that's a rather different matter.
A better categorisation and one which doesn't risk either lazy, surface-level readings or entering metaphysical terrain which can only make sense once you're there (that is, the Bodhisattva question of "do I remain or do I dissolve?2) is "awake" and "asleep".
In the past I've tended to suggest that the Right Hand Path is synonymous with sleep, the idea that either mankind will be collectively or arbitrarily "saved" and, therefore, doesn't need to do anything. Awake is for those who need to do something, ideally not because they're looking to find salvation but because something within them is sufficiently noble as to make sleep unacceptable. If that is the LHP (I cannot comment on the - rather odd - reading of Rosario's) then, without a shadow of a doubt, in my opinion, Gurdjieff belongs on the LHP.
This is not just an intellectual reading of his system (which I'd characterise as Left Hand Path Sufism with strong Neoplatonic and some Buddhist influences) but it's also rooted in my direct experience with those a long way down the Fourth Way. The qualities which can be apprehended in those initiates are
identical to those who are a long way down the conscious Left Hand Path (these two groups also recognise each other as the same). These qualities include Presence so strong as to be disruptive, empowering awakening in those with the potential for it and baffling those without that potential, and the ability to change the world in complex, anti-mechanical ways. I would strongly recommend that anyone interested in the terrain finds a Fourth Way group and judges its graduates for themselves.
