24Iron Grindstone Liu
Introduction 垂示
高高峯頂立，魔外莫能知；深深海底行，佛眼覷不見。直饒眼似流星，機如掣電，未免靈龜曳尾。到這裏合作麼生？試舉看。
Stand on the highest peak, and no demon or outsider can find you. Walk the floor of the deep sea, and even a Buddha's eye won't catch you. Yet though your eye is quick as a falling star and your mind strikes like lightning, you still drag your tail behind you like a turtle. So once you arrive here, what do you do? Let's bring up a case and see.
劉鐵磨到溈山，山云：「老牸牛，汝來也。」磨云：「來日臺山大會齋，和尚還去麼？」溈山放身臥，磨便出去。
Liu Tiemo came to Guishan. Guishan said, "Old cow, so you've come."
Liu said, "Tomorrow there's a great feast on Mount Wutai. Are you going, Master?"
Guishan let his body drop and lay flat. Liu walked out.
Verse 頌
曾騎鐵馬入重城，
勅下傳聞六國清。
猶握金鞭問歸客，
夜深誰共御街行。
She rode an iron horse once, straight through the city walls.
Word comes down: the decree is given, the six kingdoms are at peace.
Still she grips the golden whip, asking the traveler bound for home,
deep in the night, who else rides the imperial road?
