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 Self Analysis.
This book really helped me rediscover myself! It's witty and easy to absorb; it also gives practical exercises which you can do alone or with someone else. They improve your memory and most of all they leave you feeling cheerful and optimistic, ready to tackle life head on and really go for it!
