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.
Self Analysis really helped me see that I could help myself and my friends at home simply and easily. It contains simple and easy to use processes that can help you rid yourself of past, harmful experiences that plague your life. Try some of the processes. See if they work for you. See if you can use it and improve your life. You will find that the processes work and you will have fun! Try it and see.
