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 explained life for me. It explained people and why they sometimes do the crazy things they do. But not only that, it provided solutions to the crazy and more subtle aberrations that people have. Actual solutions, not just patch-up, temporary, feel-good methods of enduring the situations that one has going on in his or her life.
