By the side of Firdusi the epic poet, and Omar the philosopher, Sa'di the wise man, well deserves a place. His countrymen are accustomed to speak of him simply as "the Sheikh," much more to his real liking than the titles "The nightingale of the groves of Shiraz," or "The nightingale of a Thousand Songs," in which Oriental hyperbole expresses its appreciation. Few leaders and teachers have had the good fortune to live out their teachings in their own lives as had Sa'di. And that life was long indeed. Muharrif al-Din Abdallah Sa'di was born at Shiraz in 1184, and far exceeded the natural span of life allotted to man--for he lived to be one hundred and ten years of age--and much of the time was lived in days of stress and trouble. The Mongols were devastating in the East; the Crusaders were fighting in the West. In 1226 Sa'di himself felt the effects of the one--he was forced to leave Shiraz and grasp the wanderer's staff, and by the Crusaders he was taken captive and led away to Tripoli. But just this look into the wide world, this thorough experience of men and things, produced that serenity of being that gave him the firm hold upon life which the true teacher must always have. Of his own spiritual condition and contentment he says: "Never did I complain of my forlorn condition but on one occasion, when my feet were bare, and I had not wherewithal to shoe them. Soon after, meeting a man without feet, I was thankful for the bounty of Providence to myself, and with perfect resignation submitted to my want of shoes." Thus attuned to the world, Sa'di escapes the depths of misanthropy as well as the transports of unbridled license and somewhat blustering swagger into which Omar at times fell. In his simplicity of heart he says very tenderly of his own work;-- "We give advice in its proper place, Spending a lifetime in the task. If it should not touch any one's ear of desire, The messenger told his tale; it is enough."
