from the Rubiyat

XLVI.
For in and out, above, about, below,
’Tis nothing but a Magic Shadow-show,
Play’d in a Box whose Candle is the Sun,
Round which we Phantom Figures come and go.

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.

XLVIII.
While the Rose blows along the River Brink,
With old Khayyám the Ruby Vintage drink;
And when the Angel with his darker Draught
Draws up to Thee—take that, and do not shrink.
