“When you say the name of Khezr (or Khadir) in company you should always add the greeting "Salaam aliekum!" since he may be there - immortal and anonymous, engaged on some mysterious karmic errand. Perhaps he'll hint of his identity by wearing green, or by revealing knowledge of the occult and hidden. But he's something of a spy, and if you have no need to know he's unlikely to tell you. Still, one of his functions is to convince skeptics of the existence of the marvelous, to rescue those who are lost in deserts of doubt and dryness. So he's needed now more than ever, and surely still moves among us playing his great game.”
