From the song "Anthem" by Leonard Cohen
The birds they sang at the break of day...
"Start again," I heard them say
Don't dwell on what has passed away
or what is yet to be.
Ah, the wars they will be fought again
The holy dove, she will be caught again
Bought and sold, and bought again
the dove is never free.
Ring the bells that still can ring
Forget your perfect offering
There is a crack in everything
That's how the light gets in.
