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 The Way to Happiness.
This book really helped me with belief in myself and an understanding of other people. This book clears away any confusion surrounding the everyday moral choices we have to make, without making one feel guilty for those poor choices that may have been made in the past.
