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 The Scientology Handbook.
This book really helped me with life in general. This book gives you easy -to-learn and basic principals of the Scientology religion. Things that you can apply right now to your immediate life. It's easy to read and get lots of pictures. If you ever have any problems, this book can help you. It's very simple, but very powerful.
