大慧普覺禪師語錄 7.7

7.7

示眾：「永嘉道：『非不非，是不是，差之毫釐失千里。是則龍女頓成佛，非則善星生陷墜。』永嘉親見六祖來，要且只在是非裏。雲門即不然，非不非，是不是，仰面看天，低頭覷地。惺惺時直是惺惺，瞌睡時一向瞌睡，也無佛法可商量，亦無塵勞可回避，有時睡裏驚覺來，元是猫兒捉老鼠。」

Instructing the assembly, [the Master] said: "Yongjia said: 'Wrong is not wrong, right is not right; an error of a hair's breadth misses by a thousand miles. If right, the dragon girl instantly attains buddhahood; if wrong, Sunakṣatra falls alive [into hell].' Yongjia personally met the Sixth Patriarch, yet in the end he remained only within 'right' and 'wrong'. Yunmen is not so: wrong is not wrong, right is not right; look up to view the sky, bow the head to peer at the earth. When awake, just be truly awake; when sleepy, sleep all the way through. There is neither buddhadharma to deliberate over, nor worldly toil to avoid. Sometimes startled awake in sleep—it turns out to be a cat catching a mouse."
