佛果圜悟禪師碧巖錄 3.30

3.30

垂示云。問一答十。舉一明三見兔放鷹。因風吹火。不惜眉毛則且置。只如入虎穴時如何。試舉看。

The pointer says: To answer ten when asked one, to understand three when one is raised, to loose the falcon upon seeing the rabbit, to blow up a fire using the wind—sparing no eyebrows—all that aside, what about when entering the tiger's den? Try to cite it and see.
