Haida Yoga: Si 12 and the development of higher being-bodies

 

Even without conscious effort, the body produces a very fine en­ergy or material, the final product of the transformation of food, which Gurdjieff called si 12. This is the material used by the sex center which, when united with its male or female counterpart, can develop indepen­dently as a new organism. But it can also participate in a new octave within the body. When all the cells are permeated with this matter, there can be a crystallization, a formation of a second body. The way of the shrewd, the astute man—the accelerated way that Gurdjieff called "haida yoga"—includes the transmutation of the energy Si 12 for the development of the higher bodies. Gurdjieff never spoke of this delicate work, or even gave explicit indications about it, but there is a key to be found. For example, the friction within us that is necessary to produce the substance for our "I" is identical with what takes place externally between the masculine force and the feminine force in action.
