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 people better like their intentions and motives. Most people are good, however, there is a small percentage who don't want to see others get ahead in life. So they try to pull these others down. It was these negative types who used to effect me badly. I am now stronger from reading this book and more stable.
