This is the Tenth Bull, variously entitled "In the World" or "Return to Society."
Dorje Bosatsu:
Barefooted and naked of breast, I mingle with the people of the world.
My clothes are ragged and dust-laden and I am ever blissful.
I use no magic to extend my life. Now, before me, the trees become alive.
There's also a commentary:
His garden gate is closed, and even the wisest know him not. No one glimpses the beauty of his inner garden. He goes on his own way without following the steps of the ancient sages. Carrying an empty vessel, he goes to the marketplace, and leaning against a staff he comes home. Among wine-bibbers and butchers, everyone he looks upon becomes enlightened.
