Shoyoroku - Case 82: Unmon's: "Voice" and "Color"

Unmon instructed the assembly and said,
  "'To realize the way through hearing a voice, to enlighten the mind through
   seeing color' -- Bodhisattva Avalokitesvara comes with some small change
   and buys poor rice cakes. If he throws it away, he will get nice manju
   cakes instead."
