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.
I got stacks of knowledge out of Dianetics about how the mind works. I discovered what the blocks are to self-confidence. Understanding how the mind works gives me an insight on how and why people act the way they do.
