The condition between Pranayam and asana is called mudra because mudra is related to both asana and Pranayam. However, saints of ancient time described mudra powerful than asana and pranayam. The practice of yogasan makes the structure of bones of whole body strong whereas mudras are used to awaken Kundilini Power and to pierce Shata Chakra. Mudras describe about that activity which is related to the body organs which function in the body and nerves. According to yogashastra, there are about 72 thousand nerves in the center of the navel in our body.
