Thetan

Scientology concept of life-force

In Scientology, the concept of the thetan is similar to the concept of self, or the spirit or soul as found in several belief systems. The term is derived from the Greek letter Θ, theta, which in Scientology beliefs represents "the source of life, or life itself." In Scientology it is believed that it is the thetan, not the central nervous system, which commands the body.
