宏智禪師廣錄 7.151

7.151

風骨不露水泄不通。衲僧行履妙無蹤。門掩三秋兮人歸何處。
天無四壁兮月上中峯。

Manner and character are not revealed, not a drop of water leaks through; / the patch-robed monk's conduct is subtly trackless.
The gate shuts on three months of autumn—where has the person gone? / The sky has no four walls—the moon rises over the central peak.
