Case 94: "Non-Seeing" in the Ryogon Sutra

The Ryogon Sutra says, 
  "When I don't see, why do you not see what I do not see? If you [argue
   that you] see what I do not see, that is of course not what I do not see.
   If you do not see what I do not see, then it is quite natural that it
   is not a thing. Why is it not your self?"
