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 lays out a basic moral code based on common sense that anyone can follow. It is so simple but so powerful, we sometimes undermine some of the basic principals and rules that bind us together. It's a lot easier to get along with others now that I have this.
