This lovely verse accompanies Case No. 5 in The Book of Serenity. It was written by Taintong, the Chan master who provided the lovely reflections-in-verse to each of the cases in this particular koan collection.
The accomplishing work of great peace has no sign;
The family way of peasants is most pristine —
Only concerned with village songs and festival drinking,
How would they know of the virtues of Shun or the benevolence of Yao?
And this is the koan to which the verse is a companion:
A monk asked Qingyuan, “What is the greatest meaning of Buddhism?”
Qingyuan said, “What is the price of rice in Luling?”
