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.
As a businessman, I found this book to be invaluable to me, as it talks about communication and control amongst other subjects. The chapter on exhaustion itself helps to relieve the stress of everyday business problems, so much so that to make a stress-free decision is easy.
