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 book really helped me with a personal understanding of a few basics about man. You can apply the lists contained in the book to yourself at home and in this way improve you memory while remembering lots of long forgotten moments of pleasure. There are many more than you think!
