Saadi's mausoleum

All men and women are to each other
the limbs of a single body, each of us drawn
from life’s shimmering essence, God’s perfect pearl;
and when this life we share wounds one of us,
all share the hurt as if it were our own.
You, who will not feel another’s pain,
you forfeit the right to be called human.
