註華嚴經題法界觀門頌 1.110

1.110

當行中買賣，不許外人。知。噫！時人皆道王老賣瓜，以因行花得佛滿果。或云：王老是南泉，常自呼為王老師。切莫錯會。何則？南泉呌大夫，鶯吟堤畔柳；以手指庭花，蝶舞樹頭春。恐人不領，又出王老賣瓜絕情之語。若更不明，夷門亡。

Buying and selling within the guild does not allow outsiders to know. Alas! People of this age all say Old Wang sells melons, obtaining the Buddha's full fruition through causal practice flowers. Some say: Old Wang is Nanquan, who often referred to himself as Teacher Wang. Do not misunderstand! Why so? When Nanquan called the Grand Master, the orioles sang in the willows on the embankment; when he pointed his finger at the courtyard flower, butterflies danced in the spring atop the trees. Fearing people would not understand, he again produced Old Wang's melon-selling words that cut off conceptual sentiments. If it is still not understood, Yimen is defeated.
