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 Introduction to Scientology Ethics.
This book really helped me with finding out about how to improve my conditions in life. By figuring out what condition I was in, I could actually raise it and do better just by following step by step the formulas. It is great and works like magic every time.
