舉：「溈山見香嚴、仰山作餅次，溈云：『當時百丈先師親得者箇道理。』仰山與香嚴相顧云：『甚麼人答得此話？』溈云：『有人答得。』仰云：『阿誰？』溈指水牯牛云：『道道。』仰取一束草來，嚴取一桶水來，牛纔低頭喫，溈云：『與麼與麼，不與麼不與麼。』二人俱作禮，溈云：『或時明，或時暗。』」

He cited: "Guishan saw Xiangyan and Yangshan making rice cakes. Guishan said: 'At that time, the late master Baizhang personally attained this principle.' Yangshan and Xiangyan looked at each other and said: 'What sort of person could answer this topic?' Guishan said: 'There is someone who can answer it.' Yang[shan] said: 'Who?' Guishan pointed to a water buffalo and said: 'Speak, speak!' Yang[shan] brought a bundle of grass; [Xiang]yan brought a bucket of water. Just as the buffalo lowered its head to eat, Guishan said: 'Thus, thus; not thus, not thus.' Both of them bowed. Guishan said: 'Sometimes bright, sometimes dark.'"
