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 The Scientology Handbook.
This book really helped me with my children: there are some processes in the book called assists which one can use to help someone who is ill or injured to get better quickly or recover from an upset in life quickly. I use these with my children all the time and find them really useful.
