(1) In Theravada, the subsidiary awareness (mental factor) to avoid doing any harm to others, by keeping one's vows, free from anger or ill-will even if others harm one. (2) In Mahayana, the mental urge to safeguard the actions of one's body, speech, and mind, which comes from having turned one's mind away from any wish to cause harm to others and from the disturbing and destructive mental factors that had motivated one to harm others. When conjoined with a bodhichitta aim, it becomes a far-reaching attitude.
