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 Scientology: A New Slant on Life.
This book really helped me with gaining an understanding of what it means to be a professional, and it taught me how to confront anything in life. With this technology you can lead a happpier life.
