注維摩詰經 9.220

9.220

什曰：無常則無法不滅。滅而不斷故，故修善不厭。亦觀無常是泥洹道，泥洹道則背善本。今不住無為，故不厭有也。

[Kumāra]jīva says: In impermanence, there is no dharma that is not extinguished. Because it is extinguished without being severed, one cultivates goodness without tire. It is also contemplated that impermanence is the path to nirvāṇa; the path to nirvāṇa turns away from the roots of goodness. Now, not abiding in the unconditioned, one therefore does not weary of existence.
