Charles Webster Leadbeater,
The Astral Plane
(1894)
“ So when we speak of a man as rising from one plane or subplane to another, we do not think of him as necessarily moving in space at all, but rather as transferring his consciousness from one level to another — gradually becoming unresponsive to the vibrations of one order of matter, and beginning instead to answer to those of a higher and more refined order; so that one world with its scenery and inhabitants seems to fade slowly away from his view, while another world of a more elevated character dawns upon him in its stead. ”
