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 This book touches every area of living. I most enjoyed the two rules for living. By knowing these I can conduct my life so I don't cause others problems, and even more importantly, I don't have to worry that the things I do are harmful to others.
