Man's subtle body of light, prana or lifetrons; the second of three sheaths that successively encase the soul: the causal body (q.v.), the astral body, and the physical body. The powers of the astral body enliven the physical body, much as electricity illumines a bulb. The astral body has nineteen elements: intelligence, ego, feeling, mind (sense consciousness); five instruments of knowledge (the sensory powers within the physical organs of sight, hearing, smell, taste, and touch); five instruments of action (the executive powers in the physical instruments of procreation, excretion, speech, locomotion, and the exercise of manual skill); and five instruments of life force that perform the functions of circulation, metabolization, assimilation, crystallization, and elimination.
