若彌勒得滅度者。一切眾生亦當滅度。所以者何。諸佛知一切眾生畢竟寂滅。即涅槃相不復更滅　三約平等寂滅解脫德破。涅槃此云滅度。若法本不生。今即無滅為寂滅者。即一切眾生本來滅度。豈彌勒獨證之耶。肇曰。本性常滅。今復何滅。生曰。然終既至滅始滅驗矣。始若果滅終。豈滅哉。然知眾生即涅槃相不復更滅。是盡為滅而不滅也。

"If Maitreya attains extinction, all sentient beings should also attain extinction. Why is this? The Buddhas know that all sentient beings are ultimately quiescent and extinguished; this is the mark of nirvāṇa, and they do not undergo extinction again." Third, this refutes it in terms of the equal quiescence and extinction, which is the virtue of liberation. Nirvāṇa is translated here as extinction. If dharmas are originally unarisen, then currently having no extinction constitutes quiescence and extinction; thus all sentient beings are originally extinguished. How could Maitreya alone realize it? Sengzhao says: The original nature is constantly extinguished; what is there now to be extinguished again? Daosheng says: When the end reaches extinction, the extinction at the beginning is verified. If the beginning were indeed extinguished, how could the end be extinguished? Knowing that sentient beings are themselves the mark of nirvāṇa and do not undergo extinction again means that complete extinction is in fact non-extinction.
