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 showing people how to find out what was causing them to go "up and down" all the time. Life can be a joyous experience or it can be quite the opposite. Just reading and using the techniques and data in this book has improved my life tremendously.
