維摩經玄疏 1.90

第六、明起經論者，夫佛法至理，不可以言宣，豈存言方語本十二部乎？但十方諸佛為利眾生，皆用悉檀赴緣而起十二部經也。十二部經名義具出悉檀大本，就此即為五意：一，明悉檀起十二部經；二，明悉檀起八萬四千法藏；三，明悉檀起漸頓經教；四，明悉檀起大小乘論；五，明悉檀起聖說法、聖默然。

Sixth, clarifying giving rise to the sūtras and treatises: now, the ultimate principle of the Buddha-dharma cannot be expressed in words; how could there reside in spoken sounds and language the original twelve divisions? It is merely that the Buddhas of the ten directions, in order to benefit sentient beings, all use the siddhāntas to respond to conditions and thereby give rise to the twelve divisions of sūtras. The names and meanings of the twelve divisions of sūtras are fully set forth in the great text on the siddhāntas. In this regard there are five points: first, clarifying that the siddhāntas give rise to the twelve divisions of sūtras; second, clarifying that the siddhāntas give rise to the eighty-four thousand dharma-stores; third, clarifying that the siddhāntas give rise to the gradual and sudden scriptural teachings; fourth, clarifying that the siddhāntas give rise to the treatises of the Great and Small Vehicles; fifth, clarifying that the siddhāntas give rise to noble exposition of Dharma and noble silence.
