the person himself—not his body or his name, the physical universe, his mind, or anything else; that which is aware of being aware; the identity which is the individual. The thetan (spirit) is described in Scientology as having no mass, no wavelength, n o energy and no time or location in space except by consideration or postulate. The spirit then is not a thing. It is the creator of things. The term was coined to eliminate any possible confusion with older, invalid concepts. It comes from the Greek letter theta (0?-), to which an n is added to make a noun in the modern style used to create words in engineering. It is also 0?-n, or "theta to the nth degree," meaning unlimited or vast. See also postulate and theta in this glossary.—Games Congress Gls (Approved 13.8.92)
