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 The Dianetics Picture Book.
This book really helped me with life. It is very simple and easy to understand. I learned about how the mind can affect the body and I know now how to get through some problems in life, which I never knew before.
