The world in which we live can only be experienced in the head… Without the brain we cannot experience this “place.” Thus, any experience is subject to the territory of mind, which intertwines with the brain’s neuro-synapses.
This means that even when you do astral project, have dreams, take a psychedelic, or experience some “transcendental” state, you aren’t going anywhere, for it all is held in Mind. There are no “places,” all exists within a spaceless ‘space.’
