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 how to evaluate the behavior and actions of others - actually I'm protected from those people who have less than honorable intentions with myself or others. I can see them coming a mile away. If you can spot a bad apple in life you don't put yourself in a position to be used by them.
