The Causal Body is the vehicle of the immortal principle of man, the Ego, which survives the death and disintegration of the lower bodies- physical,astral and mental. It acts as a receptacle for the essence of man's experiences and lessons in his various incarnations. In the Causal Body also lies the creative power of meditation.

This classic work by Col. Arthur Powell is part of a series of books seeking to provide a condensed synthesis of the considerable literature given by well-known Theosophical writers. Other books in the series are The Etheric Double, The Astral Body, The Mental Body, and The Solar System.
