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 Self Analysis.
This book really helped me to be happy and cheerful. I felt more positive about my life when I did the exercises in the book by myself many years ago. Recently I received the exercise with another person & I feel I've gained so much more energy and love and ability to be kind to others. Doing these procedures have helped me have deep insights into understanding myself & others.
