The wings of Daylight by W.S. Merwin

Brightness appears showing us everything
it reveals the splendors it calls everything
but shows it to each of us alone
and only once and only to look at
not to touch or hold in our shadows
what we see is never what we touch
what we take turns out to be something else
what we see that one time departs untouched
while other shadows gather around us
the world’s shadows mingle with our own
we had forgotten them but they know us
they remember us as we always were
they were at home here before the first came
everything will leave us except the shadows
but the shadows carry the whole story
at first daybreak they open their long wings
