It’s something of a mystery,
this minute rain downloading from
the sky so slowly and invisibly
you don’t know when it came except
at dusk the grass is suddenly wet,
a visitation from the air,
precipitant from spirit world
of whitest incarnation or
reverse transfiguration, herald
of river, swamp and ocean breath
sent heavenward, released to earth
again to water weed and stone,
and shatter rainbows in the sun,
the purest liquid that exists,
too fine to slake our human thirst.
