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: The Modern Science of Mental Health.
This book really helped me with my life in so many ways! In this book, you learn about a state of being called "Clear". I am Clear and have learned from this book how to help others to improve their conditions in life and really LIVE! If you ever wanted to know what Dianetics and Scientology are really all about, the best way is to start with this book.
