法華玄論 9.90

答：《華嚴》、《梵網》、《像法決疑》、《大涅槃》及《法華．信解品》，此等諸文皆明法身常、應化身無常，與《攝大乘論》同。《法華．壽量品》可具二義，壽命無量劫，久修業所得，此是報佛，即名常樂法身也。純化菩薩名為舍那者，如化千世界微塵菩薩，無有凡夫二乘，此可名舍那，無常身也。若化二乘及三乘雜眾名釋迦，化佛也。撿眾經與諸論，皆不相違也。

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.
