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 predicting human behavior at any level, in the individual, my family and my group. It was shocking and amazing to learn the real truth about some people I know. It exposed the good and the bad. I now know with certainty who to trust and who to distrust. I know who to associate with and am a much happier person as a result.
