At one time the Buddha was staying at Sāvatthī in the Jeta Grove, Anāthapiṇḍika’s Monastery. At that time Venerable Udāyī was skilled in archery. And because he disliked crows, he shot them. He cut off their heads and then set them out in a row impaled on stakes. The monks asked him, “Who killed these crows?” “I did. I don’t like crows.” The monks of few desires complained and criticized him, “How can Venerable Udāyī intentionally kill living beings?” … “Is it true, Udāyī, that you do this?” “It’s true, sir.” The Buddha rebuked him … “Foolish man, how can you do this? This will affect people’s confidence …” … “And, monks, this training rule should be recited like this:

Final ruling ‘If a monk intentionally kills a living being, he commits an offense entailing confession.’”

Definitions A: whoever … Monk: … The monk who has been given the full ordination by a unanimous Sangha through a legal procedure consisting of one motion and three announcements that is irreversible and fit to stand—this sort of monk is meant in this case. Intentionally: knowing, perceiving, having intended, having decided, he transgresses. A living being: an animal is what is meant.
