成唯識論了義燈 3.24

3.24

一、常無常差別。剋性無常，相從是常；攝相歸性常，相用別論無常。故《涅槃》二十二云：「善男子，有為之法，生亦是常，以住無常，生亦無常。住亦是常。以生生故，住亦無常，異亦是常。以住無常，異亦無常，壞亦是常。以本無今有故，壞亦無常。」

First, the distinction between permanence and impermanence: regarding intrinsic nature, they are impermanent, but in conforming to their underlying nature, they are permanent; when phenomena are subsumed into the nature, they are permanent, while when examining characteristics and functions separately, they are impermanent. Therefore, the Mahāparinirvāṇa Sūtra, fascicle twenty-two, states: "Good son, conditioned dharmas: arising is also permanent, yet because abiding is impermanent, arising is also impermanent. Abiding is also permanent, yet because arising arises, abiding is also impermanent. Change is also permanent, yet because abiding is impermanent, change is also impermanent. Destruction is also permanent, yet because there is existing now what was previously non-existent, destruction is also impermanent."
