One of the most important diagnostic techniques of Ayurveda is pulse diagnosis: "Nadi Vijñan", meaning "pulse" and "diagnose". Pulse diagnosis is the ancient art and science of detecting the existing status of a person’s body, mind, soul and spirit. Nadi or pulse is that vital flow of energy or life that flows as a subtle channel all over the body, and enables the vaidya, the ayurvedic doctor, to feel the way the blood spurts from the heart, this helps an experienced doctor to diagnose and treat various ailments or to prevent their occurrence. Pulse reading is a miraculous science Ayurveda has bestowed on us, it is possible to diagnose the imbalances within our body without the use of any instrument except fingers, even several problems that remain undiagnosed with the aid of sophisticated diagnostic tests can be accurately judged by examining the pulse.
