Weaving the Morning
One rooster cannot weave a morning.
He will always need other roosters:
one to catch the cry that he
and toss it to another, another rooster
to catch the cry that a rooster before him
and toss it to another, and other roosters
that with many other roosters crisscross
the sun threads of their rooster cries,
so that morning, from a tenuous tissue,
will grow by the weaving of all roosters.
And enlarging into a fabric, involving all,
erecting itself into a tent where all may enter,
extending itself for all, in the canopy
(the morning) that floats without any frame:
the morning, a canopy made of a weave so airy
that, once woven, it rises by itself: balloon light.
