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.
I learned about the inner workings of the mind. With this data, I came to understand more about myself and those around me. This book can help anyone pull out of the past and start to really live in the present. You'll love this book.
