The physical manifestation you call your self arises from the perpetuation of a thoughtform that is a collectively generated entity. By agreement of the collective with the personal perception and identification, certain patterns of expression are held in place.
Release and transcendence of these patterns is a function of consciousness. A shift in consciousness has potential to shift the physical. The trick in precipitating such a shift is in liberating oneself from the influence of continuous reinforcement of the defining thoughtform through a reorientation of self-perception – a redefinition that occurs in a space outside of time and its limitations.
