What does it mean to stop herding cattle when the air is clear at night?

Prevent delusions from flying around like swans during meditation. Yuanyang is a swan.

On a clear night, you can't just herd cattle or even destroy other people's crops without anyone knowing. Abiding by laws and regulations, even without supervision, is a gentleman's "cautious independence." The Buddhist scriptures also say, "You monks have been able to keep precepts, so do five things, and don't let them escape into the five desires. For example, cattle herders watch with sticks and don't let prisoners grow crops. " Ordinary people don't know how to obey the law, don't know how to keep the precepts, run amok and create bad karma before practicing (practice refers to correcting their wrong thoughts and behaviors). Horri-bull, for example, is wild, driven by lust, and encroaches on other people's crops.
