Dance, when you're broken open.
Dance, if you've torn the bandage off.
Dance in the middle of the fighting.
Dance in your blood.
Dance, when you're perfectly free.
-- Jelaluddin Rumi (13th century)

Here is the whole poem.

Dance when you're broken open.
Dance when you've torn the bandage off.
Dance in the middle of fighting.
Dance in your blood.
Dance when you're perfectly free.
Struck, the dancer hears a tambourine inside her,
like a wave that crests into foam at the very top,
Begins.
Maybe you don't hear that tambourine,
or the tree leaves clapping time.
Close the ears on your head,
that listen mostly to lies and cynical jokes.
There are other things to see, and hear.
Music. Dance.
A brilliant city inside your soul!
--Rumi
