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 55!
This book really helped me to learn about communication: how it works, what is it, how I can use it to improve my life and how I can help others using good communication. Its made my life easier to live because there's no substitute for really good communication.
