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 Art.
The most important thing about this book is that it gets you thinking like an artist. If you read this book, good things will happen to you. Not that you're not thinking this way already, and not because of the book alone, but because it gets you thinking more and more like an artist, and you will soon find yourself in a situation where this will pay off.
