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 knowing true answers to the mind. Dianetics simply made sense. I had read several books on the subject of the mind and it was the first one that made sense to me.
