It's just an approximation
of your position on Earth,
and Earth's progress in its daily rotation.
You can read your clock
by the shadow of a memorial pillar,
its point gradually tracing
an almond-curve across the landscape.
Now take up your shrine
and move against the rotation of the Earth,
that is toward the West:
the shadow slows. Move East:
the shadow quickens.
Your friend standing to the North,
her shadow is longer, and moves quickly.
Every man and every woman has a clock,
of no use but true
to the minute and second,
each according to its relation to all.
