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 lays out in great detail the different personality characteristics you encounter everyday. After reading this book I had the ability to determine who in my life was helping me achieve my goals and who was in the way. You will be quite suprised what you will find.
