MEST - Scientologist Terminology

MEST is an acronym coined by L. Ron Hubbard to define the physical universe. Drawn from the words Matter, Energy, Space and Time, it is frequently used in Scientology texts as an adjective to describe anything physical, so you may read of the "mest body" or "mest universe".

It is only through completely understanding MEST and one's relationship with it, that an individual can become "clear", according to Scientologists. Overcoming the restrictions of mest enables the true person, the "thetan" to gain strength and ability.

"The movement of matter or energy in time is the measure of space. All things are mest except theta." http://www.fza.org/pilot/diary/

"Absolute good and absolute evil do not exist in the mest universe."
