汾陽無德禪師語錄 2.149

2.149

While Yaoshan was reading a sūtra, a monk asked, "The Venerable usually does not permit people to read sūtras; why do you read them yourself?"
Yaoshan said, "I only want to shade my eyes."
He asked, "May I emulate the Venerable?"
Yaoshan said, "If you read it, even cowhide would surely be pierced through."
