佛果圜悟禪師碧巖錄 2.30

2.30

垂示云。斬釘截鐵。始可為本分宗師。避箭隈刀。焉能為通方作者。針劄不入處。則且置。白浪滔天時如何。試舉看。

The pointer says: Chopping through nails and slicing through iron, only then can one be an authentic lineage master. Dodging arrows and avoiding knives, how could one be an adept of comprehensive mastery? The place where a needle cannot penetrate may be put aside for now; when the white waves surge to the heavens, what then? Try to bring it up and see.
