In the book, first published in 1950, Hubbard wrote that he had isolated the "dynamic principle of existence," which he states as "Survive," and presents his description of the human mind. He identifies the source of "human aberration" as the "reactive mind," a normally hidden but always conscious area of the mind, and certain cellular recordings, "engrams," stored in it. Dianetics describes counseling (or "auditing") techniques which Hubbard claimed would get rid of engrams and bring major therapeutic benefits. (See the main article on Dianetics for a fuller description of its conceptual basis).
