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 Dianetics: The Evolution of a Science.
This is the first book I read. It was given to me in a time of great pain and unhappiness. After reading it, I began to understand how the mind works and that I finally could handle the negative reactions that had been holding me back in my career and in relationships. It is a book that is not hard to read but opens a new world for you.
