佛果圜悟禪師碧巖錄 6.18

6.18

"The tiger's head and the tiger's tail are gathered up at once: (The sword that kills people, the sword that brings people to life. It took this monk to achieve this. A thousand soldiers are easy to find, but one general is hard to seek.)
his imposing authority chills the four hundred prefectures! (Sitting and cutting off the tongues of everyone under heaven. Covering heaven and covering earth.)
Yet asking, he did not know it was so perilous— (You cannot wield a blind flail and a sightless staff. Xuedou originally did not know it yet. The Ācārya will soon get it.)
the Master said, 'Letting him off by one move.'" (If not letting him off, what then? Everyone under heaven all at once loses their footing! He struck the meditation bench once.)
