This is the second day of this, September, 2025, seven day. Sesshin. Yesterday, we covered some biographical material on the great Rinzai master Hakuin from the book The essential teachings of Zen master Hakuin, translated by Norman Hua Dao. And today we're going to turn to one of the texts in this collection, which is organized into five chapters and taken together. Waddell says they express hakuins vision for authentic Zen practice, which, at the time, had been on the decline for many years. We'll start with the first chapter. It's titled, licking up chi kangs Fox slobber. I won't read it in its entirety, word for word, because it contains a lot of details, more than we need to hear, especially the names of various people and places, kind of makes it tedious to read aloud. All right, so Hakuin begins long ago, the Zen priest Yuanwu delivered a series of lectures in which he commented on the 100 cases of the blue Cliff record, which is the Hekiganroku in Japanese. A fellow priest sent him a letter of reproach using a tone of language harsher than one would expect from one's own flesh and blood. But Yuanwu realized the justness of the criticism and ceased from writing such commentaries. This ought to be a valuable lesson for us all. So let's, let's stop here for a moment. So Yuanwu is, or was, the compiler of the blue Cliff record, so why would he be harshly criticized for commenting on the koans that appear in it. And why did he come to agree with this criticism as a valuable lesson for us all.
