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 Scientology: A New Slant on Life.
This book really helped me with solving problems and overcoming barriers that we all face in our day-to-day lives. It covers every aspect of living through Scientology and is very easy to understand.
