Shundo David Haye – Zen Priest

When Zen master Nanquan Puyuan ascended the Dharma seat in the hall, the official Lu Geng said, “We invite the Master to expound the Dharma for the
sake of beings.”
Master Nanquan said, “What would you have me say?”
Lu Geng said, Can the Master offer no expedient method to enter the Way?
The master said, “What do you say is lacking?”
Lu Geng said, “Why are there six realms and four modes of birth?”
Nanquan said, “I don’t teach that.” (Zen’s Chinese Heritage)

I would advise the official to wonder why he thinks there are expedient methods to enter the way. I would add: don’t be asking “Why?” questions now.
