engramic commands (such as "I can't tell you," "It's not here") which deny the
existence of
phrase or
incident.
engramic commands which, literally translated, mean that the
engram doesn't exist. "I'm not here," "This is getting nowhere," "I must not talk about it," "I can't remember," etc. Commands which make the
preclear feel there is no
incident present.
