In the Hindu tradition, the five elements - fire, earth, water, air (wind) and ether - are represented as vayus. The vyana vayu is connected with the element of water. It has no specific seat or location, but runs through all the nadis of the body (of which there are more than 72,000 pathways), thereby connecting all functions of the body.
Being aware of the life-giving air of vyana can help the yogi obtain optimum benefits from yogic practices, as the movement of prana throughout the body is the essence of yogic practice.
When vyana is unhealthy or imbalanced in the body, one may feel physically or mentally clumsy, disjointed and/or otherwise altered.
