An immortal spiritual being; the human soul. The term soul is not used because it has developed so many other meanings from use in other religions and practices that it doesn’t describe precisely what was discovered in Scientology. We use the term thetan instead, from the Greek letter theta ( ), the traditional symbol for thought or life. One does not have a thetan, something one keeps somewhere apart from oneself; one is a thetan. The thetan is the person himself, not his body or his name or the physical universe, his mind or anything else. It is that which is aware of being aware; the identity which IS the individual.
