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 where Phantom Figures
come and go.

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.

The Rubaiyat of Omar Khayyam
