大慧普覺禪師語錄 6.25

6.25

Ascending the hall, [the Master] cited: "Qianfeng instructed the assembly, saying: 'When one thing is brought up, a second must not be brought up; let one move slip by, and one falls into the secondary.' Yunmen came out from the assembly and said: 'Yesterday someone came from Tiantai and went instead to Jingshan.' Qianfeng thereupon called to the karmadāna, saying: 'Tomorrow there must be no general labor.'"
The Master said: "Qianfeng washed his face and touched his nose; Yunmen ate his rice and bit on sand. The two suddenly met—turns out they were old enemies after all! Even though it is like this, only the Old Barbarian is permitted to know; the Old Barbarian is not permitted to understand."
