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 Problems of Work.
This book really helped me with starting my practice ... and of course, keeping it going, and expanding!! I no longer experience times of exhaustion and if I do ... I know what to do!! Find out for yourself by reading this work by L. Ron Hubbard!!
