The patient is relieved and is comforted by the settled attention she receives and then gives back to herself. The doctor feels refreshed. While taking the patient's pulse he spontaneously refers to his own pulse, a self-referral process that infuses bliss into his own physiology. It's always the joy of the doctor to be able to take the pulse. The sense of touch is the only sense that can experience itself.
Touch is therefore a path for the self-referral flow of awareness.
The pulse of someone else gives deep knowledge from the heart of that person. It sounds mystical but Ayur-Vedic pulse can by systematically learned by anyone. It is taken with three fingers on the radial pulse at three different levels of pressure. Vata governs movement, Pitta governs metabolism, and Kapha governs structure. We are born with a unique combination of these doshas that makes up our constitution.
