Mumonkan, Koan 4 (update)

I've become satisfied with my answer to this one, so I checked Mumon's notes. His interpretation is akin to my reaction, but he's a bit more specific. He suggests that differentiating between Bodhidharma with a beard and without a beard is already focusing yourself in the wrong direction. Makes sense. Like people who complain about paintings of a black Jesus. Kind of missing the point.
