佛果圜悟禪師碧巖錄 2.31

2.31

【一七】舉。僧問香林。如何是祖師西來意（大有人疑著。猶有這箇消息在）林云。坐久成勞（魚行水濁。鳥飛落毛。合取狗口好。作家眼目。鋸解稱鎚）。

[Case 17] A monk asked Xianglin: 'What is the meaning of the ancestral master coming from the West?' (Many people doubt this. Still there is this piece of news). / Xianglin said: 'Sitting long brings fatigue' (Fish move, the water grows turbid; birds fly, feathers fall. It would be better to shut that dog's mouth. The eye of an adept. A saw cutting through an iron scale-weight).
