The Etheric Double: The Health Aura of Man (Revised)Paperback - Revised, 1 January 1997

First published in 1925, this classic text has long been used as a resouce by students and scholars of astral phenomena. Its subject is the subtle body which all human beings possess, physical in nature but invisible to ordinary eyes. Of interest to healers, body workers, and all students of esoteric lore, Powell's discussion of the anatomy of the subtle body, its energy centers, and functions is perceptive and comprehensive.
