(Vyāna Vāyu): “Outward moving wind,” one of the five vayus (vital airs). It moves from the core to the periphery, pervading the entire body and causing the circulation of blood. It is also called “omnipresent prana.” Vyana Vayu pervades the whole body, regulating and controlling all movement. It connects and coordinates the other four vayus, keeping them balanced and nourished. Read more about the vayus.
