仁王護國般若波羅蜜多經疏 3.170

3.170

Explanation: The Buddha personally manifesting his body as either great or small refers to the seventh and eighth [types of transformation]: contracting and expanding. Manifesting the land where he abides as either pure or defiled refers to the eleventh and twelfth: concealing and revealing. All these above are meant to shatter conceptual clingings: dispelling phenomena as one or many, dispelling marks as great or small, dispelling bodies as ordinary or noble, dispelling buddhas as superior or inferior, and dispelling lands as pure or defiled; shattering the delusive discriminations generated by sentient beings since beginningless time—seeing the one as determinately one, seeing the many as determinately many, and so forth up to seeing the pure as determinately pure, and seeing the defiled as determinately defiled—which is grasping at phenomena (dharma-grāha). Beholding the Buddha's supernormal transformations, they awaken to the fact that phenomena arise from the mind and realize that characteristics are none other than the nature, thereby dispelling all attachments. Furthermore, the Benji says: “Transformations have three intents: first, filling space, where one flower enters immeasurable flowers, which exists to eliminate the obstacle of not delighting in the Great Vehicle; second, transmutation, where one buddha-land enters immeasurable buddha-lands, which exists to eliminate the obstacle of clinging to what belongs to the self; third, manifestation, where one buddha-body enters immeasurable bodies of sentient beings, which exists to eliminate the obstacle of fearing saṃsāra.”
