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 55!
Dianetics 55! - is a book which gave me some very basic material on myself and the basic mechanisms and motives of why myself and fellow man operate the way we do, and what can be done to change the parts of life and man's operation, which are not survival for any of us.
