法華玄論 2.11

2.11

答：光宅雲公言：猶是無常。所以然者，教有五時，唯第五涅槃是常住教，四時皆無常。法華是第四時教，是故佛身猶是無常。又此經自說無常，如下文言「復倍上數」，雖復稱久終自有限，故知無常。又〈藥草品〉云「終歸於空」，終歸於空者既是無常，終入無餘也。

Answer: Master Yun of Guangzhai said: It is still impermanent. Why is this? The teaching has five periods, and only the fifth, the Mahāparinirvāṇa-sūtra, is the teaching of permanent abidance; all the four periods are impermanent. The Lotus Sūtra is the teaching of the fourth period, and therefore the Buddha-body is still impermanent. Furthermore, this sūtra itself speaks of impermanence, as the text below says, 'again twice the above number'; although it is called long, it is ultimately limited, so we know it is impermanent. Furthermore, the Chapter on Medicinal Herbs says, 'ultimately returning to emptiness'; since 'ultimately returning to emptiness' is impermanent, it ultimately enters the [nirvāṇa] without remainder.
