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 Self Analysis.
This is a great book that will let you learn more about yourself. It talks about you and your true potential. It will assist you in understanding yourself better. I like this book a lot because it gave me a deeper understanding about myself. It is fun to know more about one's self.
