If you want to find out more about Dianetics and Scientology, the best way to do this is to read an L. Ron Hubbard book on the subject. I personally recommend you read Dianetics: The Modern Science of Mental Health.
This book really helped me with understanding the reactive bank* & becoming a Dianetics counselor & thereby helping others to get rid of all their troubles, hurt pain etc, a very worth while action.
