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 with understand my fellow man, a very rational approach to improving our conditions -- improving my ability to live life better. It resolved some very basic and important concerns I had regarding life -- what it means to be human -- I had always been concerned with questions of life, this book very clearly and easily explained those factors. Dianetics delivers without "mumbo jumbo" .
