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 How to Use a Dictionary.
This book really helped me with my study and learning. I can now use a dictionary very well, without having to put a lot of effort into finding the word and getting frustrated before I get to know what the word means. It has made my learning more interesting.
