thetan

noun

Etymology: c. Mid 20th c., Coined by Scientology founder L. Ron Hubbard, from theta + -n, from Ancient Greek θῆτα (thêta, “theta”), used in Scientology to represent the source of life.

1. A soul, spirit or being.

   “Actually a thetan is in a very, very small amount of mass. From some experiments conducted about fifteen or twenty years ago – a thetan weighed about 1.5 ounces!”

   “According to Scientology doctrine, each human being is actually a thetan or spirit, an immortal, godlike expression of the life force (theta). […] In his writings, Hubbard traces the existence of this life force back trillions of years. In the beginning theta was separate from the physical universe. Theta had no energy or mass, time or location; it was simply energy. Thetans therefore existed before and are the original source of the material universe.”
