佛祖統紀 30.34

30.34

增至四十九歲時。入末法一萬年。月光菩薩出真丹國（即東土震旦也）說法滿五十二年。廣度眾生入涅槃後。首楞嚴經般舟三昧經先滅不現。餘經次第而滅。無量壽經後住百年。大度眾生然後滅去（本起經○案無量壽經云。當來之世經通滅盡。我以慈悲哀閔。時留此經止住百歲。其有眾生值斯經者。隨意所願皆可得度。南岳願文云。我今誓願。持令此經不滅。至彌勒佛出世）。

When it increases to forty-nine years, entering 10,000 years into the Final Dharma, Candraprabha Bodhisattva will appear in Cīnasthāna (that is, the eastern land, Zhèndàn), expounding the Dharma for a full fifty-two years. After delivering sentient beings extensively and entering nirvāṇa, the Śūraṅgama Sūtra and the Pratyutpanna Samādhi Sūtra will be the first to disappear and not be seen; the remaining sutras will disappear in sequence. The Sukhāvatīvyūha Sūtra will remain for a final hundred years, delivering sentient beings on a grand scale, and then disappear (Benqi jing; note: The Sukhāvatīvyūha Sūtra says: 'In future ages when the scriptures are entirely destroyed, out of compassion and pity I will specially cause this sutra to abide for a hundred years; if there are sentient beings who encounter this sutra, they may all attain deliverance according to their wishes.' The Vow of Nanyue says: 'I now vow to uphold this sutra so that it is not destroyed until the appearance of Maitreya Buddha in the world').
