(from A MUTE EATING A BITTER MELON)
Soon after he began studying with Zhimen, Xuedou boldly stepped up and asked, “Before a single thought arises, can what is said be wrong?”
Zhimen summoned Xuedou to step forward.
Xuedou did so.
Zhimen then hit Xuedou in the mouth with his fly whisk.
Xuedou opened his mouth to speak but Zhimen hit him again.
Xuedou now suddenly experienced enlightenment.
He first assumed the abbacy at Cuiyan. He later moved to Xuedou.
