SOMATIC, 1. by somatic is meant a pain or ache sensation and also misemotion or even unconsciousness. There are a thousand different descriptive words that could add up to a feeling. Pains, aches, dizziness, sadness–these are all feelings. Awareness, pleasant or unpleasant, of a body. ( HCOB 26 Apr 69) 2. body sensation, illness or pain or discomfort. “Soma” means body. Hence psychosomatic or pains stemming from the mind. (HCOB 23 Apr 69) 3. this is a general word for uncomfortable physical perceptions coming from the reactive mind. Its genus is early Dn and it is a general, common package word used by Scientologists to denote “pain” or “sensation” with no difference made between them. To the Scientologist anything is a somatic if it emanates from the various parts of the reactive mind and produces an awareness of reactivity. Symbol: SOM. (HCOB 8 Nov 62) 4. the word somatic means, actually, bodily or physical. Because the word pain is restimulative, and because the word pain has in the past led to a confusion between physical pain and mental pain, the word somatic is used in Dn to denote physical pain or discomfort, of any kind. It can mean actual pain, such as that caused by a cut or a blow; or it can mean discomfort, as from heat or cold; it can mean itching–in short, anything physically uncomfortable. It does not include mental discomfort such as grief. Hard breathing would not be a somatic; it would be a symptom of misemotion suppression. Somatic means a non-survival physical state of being.
