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 the sorrows of an abused child which were preventing me from reaching my potential. At the time I read the above book I was merely trying to survive. This book had the answers to questions, "why" questions, I'd been searching for. For that I will always be indebted to L. Ron Hubbard.
