Can you help me explain the meaning of the sentence "Bu Yizhen Yu Bao talks about Zen" in the ninth1reply of A Dream of Red Mansions?

I only take a spoonful of water, although the water is 3 thousand. It means that Jia Baoyu is only good with Daiyu. Zhuangzi >.

The Zen mind has been stained with mud and does not dance with the spring breeze: it means that I am determined to become a monk and no longer miss home. Dongpo Collection is a poem written by a monk named Shen Guo at a banquet. Don't sing partridge to the spring breeze.

Three treasures: Buddha/Sutra/Monk

The twentieth time, Daiyu asked Baoyu, "The most expensive thing is treasure, and the strongest thing is jade. What is your price and strength? " No wonder Baoyu couldn't answer. This time, on the contrary, those words seem mysterious and have only a little meaning. So Baoyu successfully passed the "make-up exam". Last time I talked about Zen, this time I used Buddhism and poetry to hide my feelings (and answered Daiyu with the words of prostitutes and singers, damn it). After they finished talking, they went on reading.

So don't watch the sequel.
