大般涅槃經集解 19.34

19.34

案僧亮曰：合第三譬也。僧宗曰：此語偏主第十一難。難云若斷身時，我亦隨斷。合答言：不離因地神明而有，故言有耳，豈可責令與陰為一？枝陰滅，我斷也。寶亮曰：明正因之性。體性不可改變，故無能殺害者。生死血肉是偏因所感，可得損傷；正因之性天然，非因所生，故不可壞。

Sengliang states: This matches the third simile. Sengzong states: These words are directed specifically to the eleventh objection. The objection argued that when the body is severed, the self is likewise severed. The matched answer states: it is said to exist only because it is not apart from the consciousness at the causal stage; how could one demand that it be identical with the aggregates? If the branch-aggregates perish, the self would be severed. Baoliang states: This clarifies the nature of the primary cause. Its substance and nature cannot be altered, so none can kill or harm it. The flesh and blood of saṃsāra are evoked by partial causes and can be injured; the nature of the primary cause is natural and spontaneous, not produced by causes, and is therefore indestructible.
