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 getting data about the human mind and the technology and tools to improve people. You get a real good understanding of how the mind works. This book gives a scientific approach to the mind. It helps put you more at cause over this area.
