After death, the person who inhabited the body has long Life Wisdom Matrix Review departed and left the decaying flesh to its own end. Of course as you know, the physical body is made up of millions of independent and to some extent self aware small consciousness such as those of the electrons, atoms, molecules, organs, etc. As I have said before, these are not to be perceived as little people, but they do have some limited sense of their existence and of their small but important part in the overall supporting gestalt that we call the body consciousness.
This body consciousness is not the directing "Identity Consciousness" that you are, and although when it is part of an operating personality, it to some extent participates in the overall body reality. It must remain independent and "out of touch" with the physical personality, yet always under its domain and reflecting its inner emotional and psychological state through the bodies overall health.
This body consciousness operates in an almost automatic way carrying out literally millions of actions, functioning in supporting the unconscious manipulations that would overwhelm the conscious personality if it was tasked with even such a simple act as scratching your nose. This simple act requires countless instantaneous manipulations that are automatic to the physical personality, never suspecting the underlying inner reality that makes that simple act possible.
