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 is also available in Danish with the title: Et Nyt Syn på Livet. The book contains a series of shorter essays on various parts of life; It is a wonderful introduction to the Scientology approach to life. Learn new things about communication, the mind, marriage and how one can be happy. I did!
