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 helping others, which is what I most like to do. I started by doing a course called the Hubbard Dianetics Auditor Course, and it was awesome to help people just by doing what it says in the book! I saw the changes in people that I applied this therapy to, and found they were happier and effectively causing what they wanted to have happen with their lives. It was truly amazing!
