大般涅槃經集解 22.11

22.11

案僧亮曰：第四事，為制戒故，示有出身血等也。法瑤曰：明果報必受也。僧宗曰：第三事也。寶亮曰：此示制戒，凡有三意：第一明法身無損，猶如滿月，雖有其事，而無所傷。第二所以無傷，引二人共鬪，本無殺心，雖死無罪。第三舉醫譬，明有此示現，必有利益也。

Sengliang states: The fourth point is that for the sake of establishing the precepts, he manifested having blood drawn from his body and so forth. Fayao states: It clarifies that karmic retribution must certainly be experienced. Sengzong states: It is the third point. Baoliang states: In this manifestation for establishing precepts, there are altogether three points: first, it clarifies that the dharmakāya is without impairment, just like the full moon, so that although there was such an occurrence, nothing was harmed. Second, regarding why there was no harm: it adduces two men fighting together who originally had no intent to kill, so that although death resulted, there was no guilt. Third, it brings up the simile of the physician to clarify that since this manifestation exists, there is inevitably benefit.
