Sublimation

Water exists in a triple state: 
          Solid, liquid, gas
At zero Celsius.
 
Even on the coldest day
Solid snow and ice quietly disappear
          Into gaseous vapor.
 
The radiant energy of the sun
          And time
Drive this transition
Until the solid ice is no more,
          Disappeared.
But no,
It still exists in the invisible vapor.
 
Do not we, aqueous beings
          -the waters of ancient seas
                   sloshing through our veins-
Exist at a triple point,
 
Slowly sublimating
Then suddenly gone,
Existing only in the hidden vapor
Of Time.
