Oh, threats of Hell and Hopes of Paradise!
One thing at least is certain — This Life flies;
One thing is certain and the rest is Lies;
The Flower that once has blown for ever dies.
LXIV.

Oh, come with old Khayyam, and leave the Wise To talk; one thing is certain, that Life flies; One thing is certain, and the Rest is Lies; The Flower that once has blown for ever dies. FitzGerald's first edition (1859). - The Rubaiyat (1120)
