The koan from Daniel Quinn's Ishmael:
With Man Gone
With Gorilla Gone
I recently picked this up out of John Daido Loori's Eight Gates of Zen.
"Too see is to be it. To see the koan is to be the koan. The only way you can see the koan is because you are the koan."--Pg. 99
I had no idea what I was getting myself into.
