In my model each band contains 3 major stages (which I refer to as levels). This would entail therefore that 21 levels overall are defined on the Spectrum. Band 1 The three levels here are referred to - in ascending order from the lowest - as Lower 3 (L3), Lower 2 (L2) and Lower 1 (L1) respectively. Lower 3 (archaic) represents the stage where conscious and unconscious are still largely confused with each other. It would culminate with the first successful differentiation (where the physical body mind of the child is understood to be separate to a degree from a more general environment that is also understood as body mind. In holistic mathematical terms this initial confusion - where (universal) form cannot be distinguished from emptiness mind would relate to the binary digits 1 and 0. Then emerging duality would be associated with 2. Horizontal, vertical and diagonal complementarity would apply to the level! Horizontal complementarity relates to the the physical and psych...
