Nan-in, a Japanese master during the Meiji era (1868-1912), received a university professor who came to inquire about Zen.
Nan-in served tea. He poured his visitor's cup full, and then kept on pouring.
The professor watched the overflow...
Astride the bull, I reach home.
I am serene. The bull too can rest.
The dawn has come. In blissful repose,
Within my thatched dwelling I have abandoned the whip and rope.
Comment: All is one law, not two. We only make the bull a temporary subject. It is as the relation of rabbit and trap, of fish and net. It is as gold and dross, or the moon emerging from a cloud.One path of clear light travels on throughout endless time.
