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 a better life. Because I found out that I have a subconsious reactive mind. Actually every person has a mind like this which controls him and make him react and feel in ways that he doesn't fully understand. I also found out that there actually is something to do about this by means of a technology developed by L. Ron Hubbard. This has helped me a lot in my life.
