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 Scientology: The Fundamentals of Thought.
This is a quite surprising approach about very basic aspects of living. I found new ways of posing problems about my life which allowed me to find solutions I was unable to see before. The newness of Scientology is practical and fascinating.
