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 everyday problems. It's a book for young and old people and it's easy to read. It's for everyone who wants a happy world. A closely related book, Dianetics, the Modern Science of Mental Health, is about methods on how to locate and remove unhappy thoughts in the mind, i.e. get them up to present time and look at them and thereby remove them so you get more aware and conscious.
