Psychosis represents a profound disruption in the mind's capacity to distinguish inner from outer, self-generated from external — what the Sutras would call a collapse of the witness-function. The perceptions and beliefs that arise are real experiences even when they do not correspond to shared reality; dismissing them forecloses rather than opens understanding. Treatment requires stabilization of the underlying neurological disruption alongside careful, respectful engagement with the person's inner world.
Each step builds on the last.
