大般涅槃經義記 2.135

2.135

經有十二，以何義故但言九部？釋言：諸經辯義不定，或時大小合為十二。小乘法中宣說十一，略無方廣，小乘未說方廣理故；大乘經法合為方廣，大乘為顯方廣理故。故《地持》云「十二部中，唯方廣部是菩薩藏，餘十一部是聲聞藏。」此經亦爾，故下文言十一部經，二乘所持；方廣一部，菩薩所持。或大乘、小乘各說九部，如《法華》說「小乘法中略無受記、無問自說及與方廣，故但有九。」小乘之中未說行因作佛之義，故無授記；法淺易諮，故無自說；未辯廣理，故無方廣。大乘法中略無因緣、譬喻、論義，故但有九。大乘眾生利根易悟，不假因緣、譬喻、論義方始悟解，是以略無。或隨義具論，大乘、小乘皆有十二。今據一門且說九部。「以如是」下，總以結之。

The scriptures have twelve [divisions]; for what reason does it only speak of nine divisions? The explanation states: the distinguishing of meaning in the various scriptures is not fixed; sometimes the Mahāyāna and Hīnayāna together make twelve. In the Hīnayāna Dharma, eleven are proclaimed, with the vaipulya omitted, because the Hīnayāna has not yet taught the vaipulya principle; the Mahāyāna scriptures and dharmas together make the vaipulya, because the Mahāyāna reveals the vaipulya principle. Therefore the Bodhisattvabhūmi says: "Among the twelve divisions, only the vaipulya division is the bodhisattva piṭaka; the remaining eleven divisions are the śrāvaka piṭaka." This scripture is also like that; therefore the text below says that the eleven divisions of scriptures are upheld by the two vehicles, while the one division of vaipulya is upheld by bodhisattvas. Or else, the Mahāyāna and Hīnayāna each speak of nine divisions, as the Lotus Sūtra says: "In the Hīnayāna Dharma, predictions, unprompted discourses, and vaipulya are omitted, so there are only nine." In the Hīnayāna, the meaning of practicing causes to become a buddha has not yet been spoken, so there are no predictions; the Dharma is shallow and easy to consult, so there are no unprompted discourses; it has not yet distinguished the broad principle, so there is no vaipulya. In the Mahāyāna Dharma, causes and conditions, parables, and treatises are omitted, so there are only nine. Sentient beings of the Mahāyāna have sharp faculties and awaken easily, not relying on causes and conditions, parables, or treatises to first achieve awakening and understanding; therefore they are omitted. Or, discussing fully according to the meaning, both the Mahāyāna and Hīnayāna have twelve. Here, relying on one approach, it provisionally speaks of nine divisions. From "With such" onward, it summarizes and concludes it.
