And the air…
Invisible, unpredictable, unreliable, playful, soothing, destructive, inspiring and life giving: The Element of Air or Wind is all these things and much more. It is the representation of all that we cannot see: our souls, our spirits, our minds, and our hearts – of that what lies beneath or beyond as some scholars say. 
Yet, Air is not always calm. Unpredictable and changing the Element of Wind can easily be a roaring hurricane as it can be a playful breeze. 
The invisible mover of things we can clearly see, the Wind influences the weather, the seasons, and therefore in a sense the essence of time itself.
