釋淨土群疑論 2.8

2.8

問曰：《涅槃經》說，捨無常色，獲得常色；受想行識亦復如是。又言，諸佛所師謂法也，以法常故諸佛亦常。此即三身凝然不遷不變。今乃言生滅不住，斯何義耶？

Question: The Nirvāṇa Sūtra says: 'Abandoning impermanent form, one attains permanent form; feelings, perceptions, volitions, and consciousness are also like this.' It also says: 'That which all Buddhas take as their teacher is called the Dharma; because the Dharma is permanent, all Buddhas are also permanent.' This means the three bodies are solidified, unmoving, and unchanging. Why do you now say that they arise, cease, and do not abide? What is the meaning of this?
