Page "Dianetics" Paragraph 42

: 3.

The auditor installs a " canceller ", an instruction intended to absolutely cancel any form of positive suggestion that could accidentally occur.

This is done by saying " In the future, when I utter the word ' cancelled ,' everything I have said to you while you are in a therapy session will be cancelled and will have no force with you.

Any suggestion I may have made to you will be without force when I say the word ' cancelled.

' Do you understand?
