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 realizing why I myself and other people behave the way they do. It has been my bible for the last 13 years. Without this book I could not have accomplished success or achieved what I really wanted in life, which is happiness, and understanding.
