During the Song Dynasty, ZM Cong-yue of Jiangxi visited ZM Shou-zhi of Yun-gai (A temple), after not many sentences, ZM Shou-zhi started to criticised:
Look at you, although travelled a long way to my mountain's top seat, but talked and behaved like a drunkard.
The red-face Cong-yue answered:
Please be kind and compassionate and not stingy to teach!
ZM Shou-zhi asked: Have you ever visited ZM Fa-chang?
Student read his speech records, already melted into heart, that is why did not go visit.
ZM Shou-zhi asked again: Have you visited Dong-shan's ZM Ke-wen?
Cong-yue answered without thinking: Dong-shan's Ke-wen? Everyday crazy and idiotic, dragging a piece of cloth-skirt, that has bad smell of urine, not counted as any ZM with great merits!
ZM Shou-zhi explained with strict dignity: Zen is there within! You go figure towards bad smell of urine!
Seeing that Shou-zhi is serious, Cong-yue followed his instructions and went to pay a visit to Dong-shan's ZM Ke-wen, from these got deep unique instruction, and came back to express his thanks to ZM Shou-zhi.
ZM Shou-zhi asked: How was the visit to ZM Ke-wen?
Cong-yue sincerely and respectfully reported: If not for your pointing out, this life is wasted/lost, thats why expressly came to thank you.
ZM Shou-zhi said: What is there to thank? Better to thank Smelly Urine.
