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 becoming an auditor and this is very important to me. An auditor is one who applies the procedure of Dianetics and Scientology to an other person to help that person get rid of shadows from the past and improve in life.
