THETAN, 1. the living unit we call, in Scn, a thetan, that being taken from the Greek letter theta, the mathematic symbol used in Scn to indicate the source of life and life itself. (Abil Ma 1) 2. the awareness of awareness unit which has all potentialities but no mass, no wave-length and no location. (HCOB 3 Jul 59) 3. the being who is the individual and who handles and lives in the body. (HCOB 23 Apr 69) 4. (spirit) is described in Scn as having no mass, no wave-length, no energy and no time or location in space except by consideration or postulate. The spirit is not a thing. It is the creator of things. (FOT, p. 55) 5. the personality and beingness which actually is the individual and is aware of being aware and is ordinarily and normally the “person” and who the individual thinks he is. The thetan is immortal and is possessed of capabilities well in excess of those hitherto predicted for man. (Scn 8-8008, p. 9) 6. the name given to the life source. It is the individual, the being, the personality, the knowingness of the human being. (Scn 8-80, p. 46) 7. energyspace production unit. (COHA, p. 247) 8. in the final analysis what is this thing called thetan? It is simply you before you mocked yourself up and that is the handiest definition I know of. (5608C––) 9. the person himself–not his body or his name, the physical universe, his mind, or anything else; that which is aware of being aware; the identity which is the individual. The thetan is most familiar to one and all as you. (Aud 25 UK) 10. a static that can consider, and can produce space and energy and objects . (PXL, p . 121 )
