Air is existence without a form.
In Ayurveda, the element Air or “Vayu” in Sanskrit, is considered to be the source of all animation. You cannot see Air but you can feel it and be affected by it.
Air alone moves everything. Any time there is motion, it means that the element of Air is present… think of clouds being blown gently across the sky or a summer breeze playing with the leaves in a tree causing Nature to sing its own tune. Air is also present in our body: it enters when we inhale air and exists as we breath out. Air brings movement to the body: to our cells, organs, nervous system and muscles.
