華嚴經義海百門 1.14

1.14

八、開涅槃者，謂不了塵顯，迷顯為生；復見塵隱，迷隱為滅。即依流動生滅之相，緣於塵上，迷心變起，謂是真實。今求生滅之相竟無起處，亦無可得，動念自亡，妄想皆滅，隨其滅處名大涅槃，故經云「流轉是生死，不動名涅槃。」

Eighth, opening nirvāṇa: Not understanding the manifestation of the dust mote, one is deluded by manifestation and takes it to be arising; seeing again the concealment of the dust mote, one is deluded by concealment and takes it to be cessation. Basing oneself upon these fluctuating marks of arising and cessation, conditioning them upon the dust mote, the deluded mind transforms and produces them, taking them to be real. Now, seeking the marks of arising and cessation, they ultimately have no place of arising, nor can they be found; moving thoughts vanish of themselves, and false conceptualisations are entirely extinguished. In accordance with that place of extinction, it is called great nirvāṇa. Hence a sūtra says: 'Transmigration is saṃsāra; non-movement is called nirvāṇa.'
