INVERSION, 1. a switch to an opposite obsessive consideration such as from compulsion to inhibition. There may be many inversions on any consideration, each leading further from self-determinism. (COHA Gloss) 2. his resistance has been overcome so that when it tries to outflow, it inflows. That’s an inversion and that’s what’s meant by inversion. A person tries to outflow, he inflows–in other words, he exactly reverses his consideration on the thing. (8ACC-8, 5410CM12) 3. the flows have exactly turned around and that’s what we know as an inversion and that’s exactly why we call it an inversion; because it’s a flow going backwards.
