Gutei heard about the boy's mischief. He seized him and cut off his finger. The boy cried and ran away. Gutei called and stopped him. When the boy turned his head to Gutei, Gutei raised up his own finger. In that instant the boy was enlightened.

When Gutei was about to pass from this world he gathered his monks around him. `I attained my finger-Zen,' he said, `from my teacher Tenryu, and in my whole life I could not exhaust it.' Then he passed away.
