- that mental mechanism set up by an engram command which, becoming restimulated and
    supercharged with secondary engrams, takes over a portion of the analyzer and acts as an
    individual being. Any command containing "you" and seeking to dominate or
    nullify the individual's judgment is potentially a demon circuit. It doesn't become
    a real live demon circuit until it becomes keyed-in and picks up secondary engrams
    and locks. (NOTL, p. 80) 
 
  - a heavily charged portion of the analytical mind which has been captured by the reactive
    mind and does its bidding, walled off by charge into a separate entity. (SOS, p. 67) 
 
  - any circuit that vocalizes your thoughts for you. That's not natural. It's an installed
    mechanism from engrams and it slows up thought. (DASF)
