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 Modern Science of Mental Health.
After reading this book, for the first time in my life I had an understanding of why people behave the way they do and what makes them tick. The subject of the mind is explained in such a way that everyone can grasp it. It is not just for the "expert" to know. The data in this book is the most valuable data one can ever get. And the only way to get it is by reading it.
