The Belleair Mission’s latest CLEAR

Clear:
an unaberrated person. He is rational in that he forms the best possible solutions he can on the data he has and from his viewpoint. He is called a "Clear" because his basic personality, his self-determinism, his education and experience have been cleared of aberrative engrams, secondaries and locks.
L. Ron Hubbard

unaberrated not aberrated - aberration:
any deviation or departure from rationality. Used in Dianetics to include psychoses, neuroses, compulsions and repressions of all kinds and classifications.

engram
recordings of moments of pain and unconsciosness. These recordings can be later brought into play by a similar word or environment and cause the individual to act as though in the presence of danger. They force the individual into patterns of thinking and behavior which are not called for by a reasonable appraisal of the situation.

secondaries
moments of acute loss, as death of a loved one, called secondaries as they depend upon an earlier engram for their force on the individual.

lock
a moment of mental discomfort containing no physical pain and no great loss. A scolding, a social disgrace; such things are locks. Any person has thousands and thousands of locks.
