Story Summary
Discover the Zen koan Nansen Kills the Cat, where Master Nansen challenges his monks to transcend attachment through a shocking act and a pair of sandals.
One day, the monks of the eastern and western halls at Master Nansen's monastery were arguing over a cat. Seeing the dispute, Nansen held the cat up and shouted to the assembly, 'If any of you can say a word of Zen, I will spare this cat. If you cannot, I will cut it in two.' The monks remained silent, unable to offer a word of insight. Nansen then proceeded to kill the cat. Later that evening, Nansen's senior disciple Joshu returned. Nansen recounted the day's events to him. Joshu immediately took off his straw sandals, placed them on his head, and walked out of the room without a word. Nansen sighed and said, 'If you had been there, you would have saved the cat.'
