大般涅槃經義記 3.314

3.314

下次結之，以是五陰是起作相可壞義故，壞五陰者名為殺生。上來正答，下嘆顯深。性雖常住而陰可殺，陰雖可殺而性恒常，故知佛法不可思議。

Next he concludes it: because these five aggregates have the characteristic of arising and producing, and the meaning of being destructible, destroying the five aggregates is called taking life. The above directly answers; below praises and reveals the profundity. Although the nature is permanent, the aggregates can be killed; although the aggregates can be killed, the nature is eternal; therefore we know the Buddha-Dharma is inconceivable.
