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 understanding emotions and personalities of different people, friends, family and co-workers. With this information and Technology, I know if they can be trusted, if they will be a real friend, where they need help, what their attitude is, etc. etc.etc.
