佛果圜悟禪師碧巖錄 5.6

5.6

The pointer says: Singly raising and independently handling; dragging through water and mired in mud; knocking and singing conducted together; walls of iron and mountains of silver. If you deliberate, you see ghosts before a skull; if you ponder, you sit beneath the Black Mountain. Clearly the bright sun illuminates the heavens; briskly the pure wind encircles the earth. Tell me, did the ancients still have any ambiguities? Try to bring it up and see.
