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 Science of Survival.
This book really helped me with being able to REALLY KNOW the people in my life. I was very surprised to find out the true intentions of people who were supposedly my friends. This book is a real eye opener. When you read this, take the extension course that goes with it. This is one of the most important books I've ever read.
