This is a story from China twelve hundred years ago.

For thirty years I searched for a master swordsman.
How many times did the leaves fall
and the branches break into bud?
But from the moment I saw the peach blossoms,
I’ve had no doubts.
Centuries later the Japanese teacher Keizan responded with his own poem:
The village peach blossoms didn’t know
their own crimson
but still they freed Lingyun
from all his doubts.
