The Rubáiyát of Omar Khayyám

LIII.

But if in vain, down on the stubborn floor
Of Earth, and up to Heav’n’s unopening Door,
    You gaze TO-DAY, while You are You—how then
TO-MORROW, when You shall be You no more?

LIV.

Waste not your Hour, nor in the vain pursuit
Of This and That endeavor and dispute;
    Better be jocund with the fruitful Grape
Than sadden after none, or bitter, Fruit.
