Sudarshan Kriya - Origin

(Sanskrit: su = right, darshan = vision, kriya means purifying action); is a rhythmical breathing process that is said to have been revealed to Sri Sri Ravi Shankar during a spell of silent meditation that he had gone into for 10 days in 1982. The theory is that the kriya allows a healthy and pleasant mind to produce chemical messengers, which travel from the nervous system to the immune system, resulting in the overall betterment of both body and mind.
