Zen Koan – Hekiganroku – No. 62 – Zen Master Ummon’s “One Treasure”

The Case

Zen master Ummon said to the assembled monks, "Between heaven and earth, within the universe, there is one treasure. It is hidden in the mountain form. You take the lantern, entering the Buddha hall, and take the temple gate, placing it above the lantern!"

Engo's Introduction

With untaught wisdom he engages in the subtle action of inaction. With unsolicited compassion, he becomes your true friend. With a single word, he kills you and saves you. In one move he lets you go and holds you fast. Tell me, who is it that comes in that way?

Verse

Look! On the ancient bank, Who is that Holding the fishing rod? Quietly moving clouds, Boundless waters, The bright moon, the white flowers of the reeds, You see by yourself!
