Answer: The Avataṃsaka, the Brahmajāla, the Sūtra on Resolving Doubts Concerning the Semblance Dharma, the Great Nirvāṇa, and the "Belief and Understanding" chapter of the Lotus [Sūtra]—all these passages explain that the dharmakāya is permanent and the response and transformation bodies are impermanent, identical with the Mahāyānasaṃgraha. The "Lifespan" chapter of the Lotus [Sūtra] can possess both meanings: the lifespan of immeasurable kalpas obtained through deeds cultivated long ago is the saṃbhogabuddha, which is named the permanent and blissful dharmakāya. Purely transforming bodhisattvas is called Rocana: like transforming bodhisattvas [as numerous as] the dust motes of a thousand worlds, without ordinary persons or the two vehicles; this can be named Rocana, an impermanent body. If transforming the two vehicles and the mixed assembly of the three vehicles, it is Śākyamuni, the nirmāṇabuddha. Examining the various sūtras and treatises, none contradict one another.
