金剛經纂要刊定記 2.58

2.58

"The two fruits, the true and the responsive": Various sūtras and treatises all speak of three bodies; here only two are explained because they have already subsumed them together. As for the three bodies, they are the dharma, reward, and transformation [bodies]. As taught in the provisional teachings: the dharmakāya is principle, untainted and asaṃskṛta; the saṃbhogakāya is wisdom, formed by the transformation of consciousness, saṃskṛta and untainted, and although it realizes principle, wisdom is yet not principle, like the sun resting in the sky. Thus principle and wisdom are divided into two. The nirmāṇakāya is a shadow and naturally must be different; hence it is said that the Buddha has three bodies. Here speaking of two is because the dharma and reward are combined: since wisdom is precisely principle, like the radiance being the jewel itself, they are collectively spoken of as the true body. As the Vimalakīrtinirdeśa says: "The Buddha's body is asaṃskṛta and does not fall into categories"; how could one say the reward essence is saṃskṛta! Furthermore, the Mahāparinirvāṇa Sūtra says: "If someone says the Tathāgata is identical with the saṃskṛta, upon death they will enter hell." Therefore here we do not speak of three, but only of two. Thus the Mahāprajñāpāramitopadeśa says: "The Buddha has two bodies: first, the true body; second, the responsive body." It also says the birth body and the responsive body are both transformation bodies.
