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: The Fundamentals of Thought.
This book really helped me with understanding how life works. It has chapters that cover data extremely important to personal relationships. With this information I've been able to handle situations and upsets that have come up between me and others that I never would have been able to handle before.
