大般涅槃經集解 9.58

9.58

案道生曰：以百姓壽為壽，感必出矣。出必無窮，若陂池也。法瑤曰：此明天人壽命皆由佛化所得，故曰從如來命出一切命也。僧宗曰：前譬明入，今譬明出也。《大品經》言「一切天人、剎利大姓，乃至居士，一切皆由菩薩所化」也。明因地之時施一切命，化功則應還於化主，故至佛則常也。

Daosheng comments: Taking the lifespan of the common people as his lifespan, when the spiritual resonance occurs [the life] must issue forth. Its issuing forth is necessarily inexhaustible, like ponds and lakes. Fayao says: This explains that the lifespans of humans and gods are all obtained through the Buddha's conversion; hence it is said that all lives issue forth from the Tathāgata's lifespan. Sengzong says: The previous simile illustrated entering; this simile illustrates issuing forth. The Pañcaviṃśatisāhasrikā Prajñāpāramitā Sūtra states: 'All gods, humans, great kṣatriya families, and even householders, all are converted by bodhisattvas.' This explains that at the time of the causal stage, [the bodhisattva] bestows all lives, and the merit of conversion must return to the master of conversion; therefore, upon reaching Buddhahood, it is eternal.
