The Primary Vayus
The body is full of prana and the movement of prana is determined by currents called vayus. These currents have a specific direction and amplitude that they use in order to maintain physiological balance in the body. The river of prana is directed equally to all areas of the body by these currents. If the river of prana becomes low because our attention is constantly being projected outward then the flow of prana will weaken all of the vayus. When the flow of prana is in excess then all of vayus will have too much energy and that energy will become displaced. It can also happen that through dams or through disinterest an area of the river will not receive adequate prana which leads to imbalance. The five primary currents are:

Balancing the activities of the vayus is the goal. When they are in balance then the possibility of true expansion and sensitivity to the more subtle levels of awareness becomes possible.
