梵網經述記卷第一 1.39

1.39

經。佛子諦聽至第一清淨者　釋曰。第二顯教所被機。此戒寬廣不同聲聞。唯人男女能受具戒。非天龍等能受此戒。今大乘戒。廣攝有情。皆入此戒。問云。何八部受菩薩戒耶。答。若八部中先已發心。亦得受戒。言八部者。謂天龍等八。又四天王各領二部名八。金剛神者。謂金剛密迹力士。雖是菩薩。而願力故受金剛神身。具如金剛密迹經說。變化人者。謂諸龍等變為人受戒。

Sūtra: Disciples of the Buddha, listen attentively ... the foremost pure ... Commentary: The second [part] reveals the capacities for whom the teaching is intended. These precepts are broad, unlike those of the śrāvakas where only human men and women can receive full ordination (upasampadā), while gods, nāgas, and so forth cannot receive those precepts. Now, the Mahāyāna precepts broadly gather sentient beings; all enter these precepts. Question: How can the eight classes receive the bodhisattva precepts? Answer: If among the eight classes they have already generated the mind [for awakening] before, they can also receive the precepts. As for 'the eight classes', it means the eight including gods and nāgas; or, the Four Heavenly Kings each govern two classes, which are named the eight. 'Vajra deities' refers to the vajra-bearing Guhyapada wrestlers. Although they are bodhisattvas, by the power of vows they assume the bodies of vajra deities, fully as expounded in the Guhyakādhipatinirdeśa Sūtra. 'Transformed humans' means nāgas and others who transform into humans to receive the precepts.
