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 Science of Survival.
This book really helped me with telling how well one is surviving in all different areas of life. It gives a person the knowledge to tell if others are aiding or hurting his survival. And, it gives anyone the tools to aid her own survival. That's a pretty good book!
