Shundo David Haye – Zen Priest

Master Chokei Eryo asked Master Hofuku Juten: When we look at matter
we are looking directly at mind. Now, can you see that boat?
Master Hofuku said: I see it.
Master Chokei: Forgetting about the boat for a while, where is the mind?
Master Hofuku pointed at the boat again. (Shinji Shobogenzo)

Is it even possible to forget about the boat, really?
