Here is an illustrated audio excerpt from Dianetics: The Modern Science of Mental Health by L. Ron Hubbard. The excerpt and the entire film, How to Use Dianetics were produced by Golden Era Productions.
This excerpt illustrates that the sentient portion of the mind—the actual computing ability of Man—is never in error. Yet if the mind always computes perfectly on the data that it has stored and perceived, how is it then that people make errors in judgment?
Just as with a machine that has a held down “7” button, when incorrect data gets fed into the human memory banks, it can cause a person to make errors and act in an abnormal manner.
Scientology Churches, Missions and groups offer Dianetics Seminars based on Dianetics: The Modern Science of Mental Health and the award-winning How to Use Dianetics film. Attendees soon become participants, helping one another with the use of Dianetics technology.
