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 and why it is so difficult at times to feel good. It explains why people do what they do, it explains all about the mind and makes more sense than anything else I have ever heard or read.
