宏智禪師廣錄 4.37

4.37

Ascending the hall, [the Master] said: "Bodhi originally has no tree, and the mirror is not a stand. / Emptiness and pure radiance receive no dust. / In the illumination, it is easy to tell flour from snow; / In turning around, it is hard to distinguish coal from ink. / Birds return to roost atop the shadowless tree; / Flowers blossom upon the branch that does not bud. / At the time when wind and clouds meet, / The cold weaver's shuttle emerges from hibernation with a crack of thunder. Examine!"
