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 understanding myself and the people around me and how to apply myself to life in general and my job in particular. I became a happy person as a result of this and could enjoy life. I realized there really is a formula to spiritual freedom which can be written as "8-8008", as stated by L. Ron Hubbard.
