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. It really helped me to understand how one can know things and have greater awareness about themselves and others. Using the techniques in this book taught me how to be more alert, have a better memory and really know more! I highly recommend it.
