佛祖統紀 36.72

36.72

述曰。罽賓害師子。而臂墮命終。沮渠刺無讖。而神人加刃。或謂聖師通達宿業方圖償債。豈當使之受報若是。意者護法之神怒其干犯尊境。而前人熾惡之心。自足以召之。非同常人互相責報之比也。

The commentary states: When Kaśmīra harmed Āryasiṃha, the king's arm dropped off and his life ended; when Juqu stabbed Dharmakṣema, a divine being struck him with a blade. Some may say that holy masters, having completely penetrated past karma, were merely seeking to repay their debts, so why should they cause the perpetrators to receive such retribution? It is likely that the Dharma-protecting deities were enraged by their transgression against a venerable presence, and the blazing malice in the perpetrators' minds was itself sufficient to summon it. This is not comparable to ordinary people exacting mutual retribution from one another.
