大般涅槃經集解 11.49

11.49

案智秀曰：人無害獸之心，獸亦不害於人，是以探鯁虎於山中、狎翔鷗於海上。若既食其肉矣，豈害心而永滅哉？所聞其殺氣，生畏死想也。

Zhixiu comments: If a person has no intention to harm beasts, beasts will not harm the person either; this is how one can probe a bone from a tiger in the mountains, or be familiar with gulls hovering over the sea. If one already eats their flesh, how could the intention to harm ever be extinguished? When they smell the killer's aura, they give rise to the thought of fearing death.
