[The Master] cited: A monk asked Caoshan: “When the son returns to the father, why does the father pay no attention at all?” Caoshan said: “In principle, it should be like this.” The monk said: “Where is the affection between father and son?” Caoshan said: “Only then is the affection between father and son accomplished.” The monk said: “What is the affection between father and son?” Caoshan said: “Knives and axes cannot cleave it apart.”
The Master said: “The emerald curtain hangs down; the silk decrees have not been issued. The purple gossamer bed-curtain is closed; seeing and hearing are hard to penetrate. Disturbing the hair's tip, the moon rises on the night door; secretly moving a single step, the crane exits the silver cage. Do you know? Casting off the body in a single hue, without leaving a shadow; not sitting in the same wind, the great merit drops away.”
