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 the way that I looked at life. It gave me a whole bunch of new data that allowed me to see life in a different way. This new outlook that I obtained put my goals in perspective and made life exciting again.
