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 Dianetics: The Modern Science of Mental Health.
This book really helped me by enlightening me to the true source of disease and illness and exposing the falsehoods that exist in the medical profession. Inversely, it exposed the true source of success.
