Defenition of Vyana:
 
Use this as an inspiration for your meditation and mantras.
 
Vyana is the force that distributes prana by causing it to flow. It expands and contracts, bends downward and upward, and travels to the side. It induces the movement of blood, lymph, and nervous impulses. It causes sweat to run. At a more subtle level, it creates the sense of living energy that we perceive as radiating throughout the entire field of our body/mind.
