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 was the first book I bought and read where L. Ron Hubbard speaks about the components of the human mind and this totally changed my attitude about myself and others. Because I understand I can now better handle situations and better myself and help others.
