When a man is struggleing just to get through the day and is feeling down and blue, a poem by a 17th century poet, Hafiz, comes to mind and it goes:

WHEN THE VIOLIN
When
The violin
Can forgive the past

It starts singing.

When the violin can stop worring
About the future

You will become
Such a drunk laughing nuisance

That God
Will then lean down
And start combing you into
His Hair.

When the violin can forgive
Every wound caused by
Others

The heart starts
Singing.
