The Relaxation Response by Herbert Benson, MD

Dr Benson is a cardiologist who started to examine the possibility that hypertension might be relieved by the mind activating the parasympathetic nervous system. His research concluded that it is indeed possible, and he wrote this little book on what he calls the Relaxation Response. In it he shows how anybody can learn to "relax" in a very specific way that will have measureable medical benefits.
