Because clouds pour over the mountains in the morning
and sea currents draw them back at noon.
Because leopard sharks whip the waters all around as
you speed on the train beneath the great bay.
Because the choreography of cells and blood and
breath never ceases as you walk the long blocks.
Because the three sisters spin in their velvet arc each
night above your dreaming brain.
Because this moment creatures of every kind are
emerging and expiring from the earth.
Because the earth itself is moving in its endless circle dance
around the sun, and time is moving,
and space, the very medium of movement,
is moving outward in its infinite hunger,
flinging the stars into new frontiers.
