One day when Fa-yen Wen-i (885-958), one of the well known Chinese Ch'an masters, has ascended his seat. From the assembly, a monk came out and asked:
-What is one drop of water from the fount of Tsao-ch'i?
Mumon's Comment 無門曰、
Nansen, growing old, had no shame. 纔開臭口、家醜外揚。
Just opening his stinking mouth, he let slip the family secrets. 然雖如是、知恩者少。
Yet there are very few who are grateful for his kindness.
The sky clears, the sun shines bright,
The rain comes, the earth gets wet.
He opens his heart and expounds the whole secret,
But I fear he is little appreciated.
