7.208

不住相者。凡夫迷真空既住相，當知悟真空即不住相也。住即執取染著之義。又凡夫顛倒不了無常，故戀世間不務修進，當知達彼一切悉無常性，念念遷謝下住不久，由是怖畏生死樂趣涅槃，如救頭然寸陰是競。所以佛於涅槃會中，偏讚此觀以為第一。然二句中各有解行，配釋可知。

"Not abiding in characteristics": ordinary people, being deluded about true emptiness, abide in characteristics; one should know that awakening to true emptiness means not abiding in characteristics. "Abiding" means the sense of grasping and defiled attachment. Moreover, ordinary people are confused and do not comprehend impermanence, hence they cling to the worldly realm and do not strive to cultivate and advance; one should know that penetrating how all things possess an impermanent nature, transmuting and decaying thought after thought without lasting long, leads them to fear birth and death and delight in nirvāṇa, like saving one's head from burning or competing for every inch of time. Therefore the Buddha, in the assembly of the Mahāparinirvāṇa Sūtra, singled out this contemplation for praise as foremost. In these two phrases, each contains understanding and practice; the paired explanation can be understood.
