淨名玄論 7.36

7.36

《大品》云「諸佛住三事，示現說十二部經。一他心輪、二神通輪、三說法輪。」他心輪，靜鑒根藥，即是實智。說法現通、應病授藥，明其動用，即權智也。初會合蓋現土、按地變淨，即是神通；明淨土因果，名為說法；他心通貫斯二。次會不疾現疾，即是神通；明法身因果，名為說法。第三空室待賓，借座請飯，名為神通；自爾之外，皆是說法。後會掌擎大眾，手移妙喜，名為神通；自爾之外，皆是說法。是故斯經，唯釋三輪。

The Pañcaviṃśatisāhasrikā says: “The buddhas abide in three matters to manifest and speak the twelve divisions of the sūtras: first, the wheel of reading others' minds; second, the wheel of supernatural powers; third, the wheel of preaching the Dharma.” The wheel of reading others' minds quietly observes the faculties and the medicines, which is real cognition. Preaching the Dharma and manifesting supernatural powers, giving medicine in response to illness, clarify active functioning, which is expedient cognition. In the first assembly, joining the canopies to manifest the lands and pressing the earth with the toe to transform it into purity are supernatural powers; explaining the causes and results of the pure land is called preaching the Dharma; knowing others' minds penetrates both of these. In the next assembly, manifesting illness while not being ill is a supernatural power; explaining the causes and results of the dharmakāya is called preaching the Dharma. In the third, emptying the room to await guests and borrowing seats and requesting food are called supernatural powers; aside from these, all is preaching the Dharma. In the latter assembly, holding the great assembly in his palm and moving Abhirati with his hand are supernatural powers; aside from these, all is preaching the Dharma. Therefore, this sūtra only explicates these three wheels.
