12.8

夫戒者防患之總名也。菩薩淨戒唯禁於心。聲聞律儀則防身語。故有託緣興過聚徒訶結。菩薩大人都無此事。佛直為說令使遵行。既無犯制之由故闕訶結之事。諸大乘經明學處者摭之。於此為菩薩調伏藏云。

Now, 'precepts' (śīla) is a general name for guarding against harm. The pure precepts of a bodhisattva restrict the mind alone, whereas the vinaya rules of a śrāvaka guard body and speech. Therefore, [in the Śrāvakapiṭaka] occasions give rise to transgressions, and gatherings of disciples lead to reproof and promulgation. For the great beings who are bodhisattvas, there is none of this. The Buddha directly expounded [the precepts] for them, causing them to uphold and practice them. Since there is no cause for transgression against prohibitions, instances of reproof and promulgation are absent. Those passages explaining the training rules in the various Mahāyāna sūtras have been culled and placed here, constituting what is called the Bodhisattva Vinayapiṭaka.
