法華義疏 3.59

3.59

三者、大明佛事凡有三輪：一、知他心，二、現神力，三、說教門。此之三輪無佛事而不收、無群生而不化，但初分經會五乘之教歸于一乘，謂說法輪。後分之經明延促自在脩短適化，則神通輪。故前文云「說佛智慧故諸佛出於世」，後章經云「如來祕密神通之力」，則其證也。

Third, broadly clarifying the Buddha's deeds, there are three wheels: first, knowing others' minds; second, manifesting supernatural powers; third, expounding the teaching gate. These three wheels leave no Buddha deed ungathered and no living being unconverted. Yet the first section of the sūtra unifies the teachings of the five vehicles to return to the ekayāna, termed the wheel of expounding the Dharma; the latter section of the sūtra clarifies extending or contracting at will, and adapting long or short lifespans to convert, which is the wheel of supernatural powers. Hence the earlier text says, "It is to expound the Buddha's wisdom that the Buddhas appear in the world," and a later chapter of the sūtra says, "the Tathāgata's secret supernatural power," which are its proof.
