Omar Khayyám - عمر خیام

خيام اگر ز باده مستى خوش باش

با ماه رخى اگر نشستى خوش باش

چون عاقبت كار جهان نيستى است

انگار كه نيستى، چو هستى خوش باش

which translates in Fitzgerald's work as:

And if the Wine you drink, the Lip you press,

End in the Nothing all Things end in — Yes —

Then fancy while Thou art, Thou art but what

Thou shalt be — Nothing — Thou shalt not be less.

A more literal translation could read:

If with wine you are drunk be happy,

If seated with a moon-faced (beautiful), be happy,

Since the end purpose of the universe is nothing-ness;

Hence picture your nothing-ness, then while you are, be happy!
