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: A New Slant on Life.
This is a book which I could read over and over, and every time learn something new about life. This book could help you understand and handle almost any situation in life. It has the basics of life laid out in simple terms.
