THETA AND MEST
In more general terms, the term theta describes the life force which animates all living things. This life force is separate from, but acts upon, the physical universe, which consists of matter, energy, space and time (called “MEST” in Scientology). Scientology is built on a series of fundamental truths called the Axioms, which define theta and MEST and describe how the two interrelate to form life as we know it. The Axioms comprise the fundamental elements of the beliefs of the Scientology religion. (See Appendix 1.)
First published in 1954, the Axioms of Scientology present this doctrinal foundation with a definition of theta as a “life static” which has no mass, no wavelength, no location in space or in time. It has the ability to influence and change its environment and achieve total knowingness.
