We come and go, but for the gain, where is it?
And spin life’s woof, but for the wrap, where is it?
And many a righteous man has burned to dust
In heaven’s blue rondure, but their smoke, where is it?

O friend, do not indulge in this world’s sorrow
From the world of vain grief and sadness, don’t borrow
The past is gone and the future is not yet here,
Be happy and fear not the sorrow of tomorrow.

Omar Khayyam
