Body elemental
A being of nature (ordinarily invisible and functioning unnoticed in the physical octave) that serves the soul from the moment of its first incarnation in the planes of Mater to tend the physical body. About three feet high and resembling the individual whom he serves, the body elemental, working with the guardian angel under the regenerative Christ Self, is the unseen friend and helper of man.
