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 understanding the mind and life. If you've ever wondered what the mind was, you need to read this book. It tells you what the mind really is and what it does. This book breaks down the significance and puts it into proper perspective so that anyone can understand it. Once you understand it, you can use it to the fullest. Your mind is the most powerful tool you have, don't undermine it.
