What are the Three Treasures?

You might be surprised. This nugget is also from Dahui's Shobogenzo. The master here, Sanjiao Zhisong, is in the Linji branch, 16th generation in China, 45 from the Buddha.

[610] Master Sanjiao was asked by a monk, “What are the Three Treasures?”

He said, “Rice, wheat, and beans.”

The monk said, “I don’t understand.”

Sanjiao said, “Everybody gladly serves them.”
