seven cardinal sins ［七逆］ ( shichi-gyaku): The seven gravest offenses in Buddhism. According to the Brahmā Net Sutra, they are (1) injuring a Buddha, (2) killing one’s father, (3) killing one’s mother, (4) killing a monk of high virtue, (5) killing an āchārya (a Buddhist teacher), (6) causing disunity in the Buddhist Order, and (7) killing a sage. Lists of the seven cardinal sins differ slightly among the Buddhist sutras and commentaries. Miao-lo’s work The Annotations on “Great Concentration and Insight” lists the five cardinal sins as killing one’s father, killing one’s mother, killing an arhat, injuring a Buddha, and causing disunity in the Buddhist Order, and adds to those killing a monk of high virtue and killing an āchārya to make the seven cardinal sins.
