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 Scientology Handbook.
This book really helped me with assists (simple, easily done processes that can be applied to anyone to help them recover more rapidly from accidents, mild illness or upsets). They have helped me to help people in upsetting situations.
