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 Introduction to Scientology Ethics.
This book allows an individual to really apply the necessary tools to really handle situations in life. These basic tools are used in any situation and are really defined so that they can be understood and applied in the right order for real gains. Without these defined steps I wouldn't have been able to help my daughter when she relly needed help.
