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 my own irrational behavior and that of others. Take a look at our world: drugs - criminals - wars etc. etc. Why do they DO that? WHY do the individuals doing this DO this? There is a reason and an explanation for irrational behavior. Understand WHY. Read Dianetics: The Modern Science of Mental Health!
