The differences between the bodies of an unascended being and an Ascended Being are these, our mental bodies are composed of the ethers, Theirs are of living flame; our feeling worlds are composed of water, Theirs are composed of fire; our physical bodies are flesh, Theirs are bodies of fire. The purpose of physical embodiment is to become master of conditions in the world of the third dimension through the flame in the heart; by invoking it and setting the powers of the Sacred Fire into action which will manifest through the individual's world. Thus one earns the right to a fire body.

A.D.K. Luk.
