Knowing vs Being

When the Tesshu, a master of Zen, calligraphy and swordsmanship, was a young man he called on the Zen master Dokuon. Wishing to impress Dokuon he said, “The mind, the Buddha, and all sentient beings after all do not exist. The true nature of phenomenon is emptiness. There is no realization, no delusion, no sagacity, no mediocrity, nothing to give and nothing to receive.

Dokuon promptly hit him with a bamboo stick. Tesshu became quite furious.

Dokuon said quietly: “If nothing exists, where did this anger come from?”
