Ancestor Dongshan Liangjie (807-869).
After some period of practice with Yunyan, just before departing to visit other teachers, Dongshan asked Yunyan,
“Later on, if I am asked to describe your reality, how should I respond?”
After a pause, Yunyan said, “Just this is it.”
Dongshan departed without further comment.
Later while wading across a stream, he looked down, saw his reflection, and awakened to the meaning of the previous exchange.

Where else are you going to find it?
Why are you searching for it anyways? How funny to see a Buddha looking for a Buddha.
Dongshan finally saw it in his own face. Right there in an instant.
Not thinking about it and there it was.
