The Same Breathing Voyage
The navigator of day
plots his way by a few daytime stars
which he never sees
except as black calculations on white paper
worked out to the present
and even beyond
on a single plane
while on the same breathing voyage the other navigator steers only
by what he sees
and he names for the visions of day
what he makes out in the dark void over his head
he names for what he has never seen what he will never see
and he never sees
the other
