The assemblage point as teaching
Castaneda's teachers describe the human energy body as a luminous egg containing all the energy fields that could be perceived. On this egg there is one specific point — the assemblage point — where energy threads are gathered and interpreted into a perceptual world. Position determines reality. The ordinary human position gives the ordinary human reality. The point can move — through dreaming, illness, ceremony, plant medicines, sustained inner work, or shock — and other equally vivid realities are perceived.
The sorcerer's discipline is not believing in alternative realities. It is moving the assemblage point at will, and underneath that, learning that one has been doing it unconsciously all along. Every reaction, every certainty, every that's just how it is was already an assemblage choice made too fast to see. This is the operational core of the body's lc-assemblage-point concept.
