景德傳燈錄 8.34

8.34

磁州馬頭峯神藏禪師上堂謂眾云。知而無知不是無知而說無知（南泉云。恁麼依師道。始道得一半。黃檗云。不是南泉駿。他要圓前話）。

Chan Master Shenzang of Matou Peak in Cizhou went up to the hall and addressed the assembly, saying: "Knowing without knowing is not speaking of unknowing out of ignorance." (Nanquan said, "Speaking according to the master like this, one has only managed to say half." Huangbo said, "It is not that Nanquan was quick-witted; he wanted to complete the previous words.")
