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 finding answers about life, myself, and others. It has given me insight into myself, how I can live more happily, and what is stopping me from living the life I want to live.
It has also provided me with answers regarding why people act the way they do. It explained to me that people CAN be helped, in a way that THEY want to be helped, and improve what THEY want to improve, and with results.
