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 with my life. I have found The Way To Happiness a fantastic guideline and it has put me back on the right road more than once. I have found it a simple yet powerful book to have and to share with people you care about.
