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 living an ethical life. There are simple rules in this book which, if followed, will help you on your way to happier living. Life doesn't have to be complicated. This book states some "golden rules" for living which, if followed, can make your life more sane in a world that seems everyday going more towards an ethical decline.
