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 deal with children - I got more knowledge about this and realized that children are the same as grown-up people in many aspects. I understand what causes conflicts between people, how to be in good communication with people, etc.
