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 book really helped me with understanding life - not in the biological or chemical sense, but in the living of life itself, what it is made up of, and how I can increase and improve my participation in it.
