So that tradition has come down through the ages, and whenever a friend wishes to express his loving farewell, he says, "Stop at the Angel's Lily!" When I heard that tradition (I took it down in shorthand in my diary), I studied upon it a long time before I could understand fully just what the old sheik meant. It was an illustration, a symbol; and as I studied long I found it reaching into all avenues of life, and, lo, it was one of the best descriptions of a philosophy of happiness that I ever saw put into any form, either in book or public speech. Because it is, after all, the place where men are happiest, half-way between Borzar, the hovel, and Bagdad, the magnificent palace of the Caliph. They learn the lesson easiest in the East, although they are not always contented there.
