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 showed me that the moral and ethical codes that I believe in are not dead, and that there are other people out there who have the same ideas about these codes. It makes a lot of sense and it can be applied by anyone who wish to make a change in their own or someone else's life for the better.
