Nails are silent
till the hammer swings.
Muscle whets muscle
when music rings.

Rocks won’t sing
till the riverbed fills.
Water wears rock
as it rolls downhill.

Flute can’t speak
till you hollow the bone:
Finger the holes
and blow through the bore!

Iron sharpens iron
in a forge called life.
Nails are silent
till the hammer strikes.
