The Rubaiyat: Quatrain XLVII

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.

This is the forty-seventh quatrain of the FitzGerald's Rubaiyat. The poet says that - If the wine you drink, and the lips of the beloved you press,  if these pleasures end in Nothing, then everything of us, everything we do, everything we part of or in midst of, all amounts to nothing in the end. Then fancy this my friend while you are here, you are nothing and you shall be in future no less, where you shall be Nothing. You shall be no less, no more from your current state of play and so do not be over joyed or over dismayed by these and live as it comes!
