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 understanding the mind. This enables you to gain control over your self and so have control over life. I found out how I can take back control of my mind and so life itself. This is the best book I have ever read.
