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 giving me lots of useful information on how to deal with things. It definitely helped me see my life can be better and I can improve all of these things. I think that this is a good introduction for anyone who wants to find out more about Scientology.
