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. For the first time I found out what made me and every person around me "tick". I was able to read and follow the procedures in the book and handle some painful past experiences which had heavily effected my life. And anyone can learn to do this.
