Prana and the Vayus
Prana is life force. It is the creative and intelligent spark of life that animates everything. It flows through channels in our subtle body and infuses our body-mind system completely. When our prana is flowing evenly and undisturbed, we are healthy; prana is balanced and calm. It is ready to respond to the needs of body-mind. It can express as light and quick, undulating, rising, heavy or expansive, inward drawing, or dispersive. All of the inner actions that animate us and keep us alive are movements of prana.
Prana spreads through us via the intricate system of the nadis (channels that contain and direct flow). These channels of flow are sometimes felt or described as rivers of light or vitality. The nadis are the pathways themselves, the banks of the river, and the prana, like liquid light, flows along and within the banks.
The vayus are the winds, or the directional forces, that propel the prana. Together the vayus support and motivate the various movements of life force that motivate different bodily functions. In other words, the vayus coordinate their movements and balance the flow of prana.
When prana flows evenly and healthfully in our body-mind we feel well. When it is obstructed, erratic, overly stimulated, or dull we feel less well. When it flows in a balanced way, prana seeps through the entire body-mind and penetrates like an even mist of vitality. We feel settled and calm. The combination of yoga asana and pranayama does a great deal to balance the flow of prana. The balancing of prana is one of the main reasons that people generally feel better after attending a yoga class.
There are said to be forty-nine vayus, ten of which are of major importance. Of the ten, five are considered to be of primary importance. Each of the five vayus has its own qualities and movement. And although, each is centered in a particular region of the body, they are also all present in every cell. Prana is the umbrella term that includes all of its discretely defined directional flows – so; the prana vayus are all movements of prana. However, it is important to understand that one of the vayus is also called prana, and the prana vayu is not to be confused with the unified prana that includes all life force.
Since there are many different descriptions of the vayus, and some are confusingly dissimilar, it seems fair to say that each serious yoga practitioner should explore the fascinating world of pranic movement for him or herself. In the descriptions below I have included material that I have read (and is easy to find in yoga texts) with my personal experiences. My hope is that this may prompt you to explore for yourself.
