Omar KhayyamYou know, my friends, with what a brave carouse I made a Second Marriage in my house; favored old barren reason from my bed, and took the daughter of the vine to spouse.
Omar KhayyamUp from Earth's Centre through the Seventh Gate rose, and on the Throne of Saturn sate; And many a Knot unravel'd by the Road; But not the Master-knot of Human Fate.
Omar KhayyamWhy ponder thus the future to foresee, and jade thy brain to vain perplexity? Cast off thy care, leave Allahโs plans to him โ He formed them all without consulting thee.
Omar KhayyamThe secret must be kept from all non-people. The mystery must be hidden from all idiots.
Omar KhayyamOld Khayyรกm, say you, is a debauchee;If only you were half so good as he!He sins no sins but gentle drunkenness,Great-hearted mirth, and kind adultery.But yours the cold heart, and the murderous tongue,The wintry soul that hates to hear a song,The close-shut fist, the mean and measuring eye,And all the little poisoned ways of wrong.
Omar Khayyam
