Wild beasts and angels

Who dances here
inside our souls?
Wild beast, or angel --
and how are we to tell
which beast is which?
They may not have been
dressed as we'd expect;
might prove more playful
than we would deem wise.
Though robed in white,
the tattered clothes might indicate
a certain shabbiness of purpose;
a willingness to bend and sway
when we assumed upright should be
the order of the day...
Help us, we pray,
to know and love them both.
