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 really helped me. After reading The Way to Happiness I became a more ethical person. It is full of simple truths that we all need reminding of from time to time. It made me feel "good" about the life I lead and example I set for others.
