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 a lot about life. It helped me to understand why people act the way they do, and why there is so much illness and madness in the world. Reading this book I realized that there is actually something to do about this. I'm therefore planning to help others to get the same understanding and I strongly recommend you to read this book!
