"Something better in return"

Should heartache enter your mind and ambush your joy, yet
it prepares the way for happiness.
Quickly it sweeps all others out of the house so that joy
may come to you from the Source of good.
It shakes the yellow leaves from the branch of the heart,
so that fresh leaves may grow continuously.
It pulls up the root of old happiness so that a new ecstasy
may stroll in from Yonder.
Heartache pulls up withered and crooked roots so that no
root may remain concealed.
Though heartache may extract many things from the heart,
in truth it will bring something better in return.

-- Mathnawi V: 3678-83
