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 Dianetics: The Modern Science of Mental Health.
This book really helped me with life. For me this book is the backbone of Dianetics and Scientology. Through the use of Dianetics you can handle ANY area of mental stress, difficulty, problem, etc. You will become more able than you believed possible and with your attention off whatever the areas causing you to be less capable, active, loving (or whatever they are causing you to be), you will have more focus on what you really want to do.
