- Mumon’s comment: If anyone can open one eye at this point and say a word of Zen, he is qualified to repay the four gratifications, and, not only that, he can save all sentient beings under him. But if he cannot say such a word of true Zen, he should turn back to his tail.

- If he returns, he will be butchered.
- That little tail
- Is a very strange thing.
