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 Way to Happiness.
This book gave me the tools to show others that there was a way to achieve happiness despite the pressures that life throws at you. It is the first non-religious moral code based purely on common-sense ever written and thus it is easy to read and apply.
