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 Scientology: A New Slant on Life.
This book really helped me with understanding the basics of life. I understand what communication & understanding are. I learned about marriage, children and people in general. Most of all I learned what greatness was: To love your fellow man despite of all invitation not to.
