梵網經古迹記 2.232

2.232

述曰：說是非而破，唯在內家，非外道等之所能也。如《蓮華面經》云：「佛告阿難：譬如師子命終，若空、若地、若水、若陸，所有眾生不敢食師子身肉。唯師子自生諸虫，自食師子虫之肉。阿難！我之佛法非餘能壞，是我法中諸比丘破我三大阿僧祇劫積行勤苦所集佛法。」

The commentary states: Speaking of rights and wrongs so as to destroy [the teaching] occurs only within the household [of Buddhism]; it is not something that non-Buddhists and the like are capable of. As the Padmamukha-sūtra states: "The Buddha told Ānanda: 'For example, when a lion dies, whether in the air, on the ground, in the water, or on land, no sentient beings dare eat the flesh of the lion's body. Only the worms born from the lion itself eat the flesh of the lion's worms. Ānanda! My Buddha-Dharma cannot be destroyed by others; it is the monks within my Dharma who destroy the Buddha-Dharma accumulated through my diligent toil across three great asaṃkhyeya kalpas of accumulated practice.'"
