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. It gave me understanding of other people's behavior (and my own) and taught me to predict how a particular person would react in a tough situation. Knowing this data has helped me to successfully choose my friends and business associates.
