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 understand that life is a game in which there are many more games of one's choosing. And when one knows the rules of the game in regards to what is right or wrong, life becomes much more enjoyable and full of fun where we all can play and win.
