俱舍論記 18.80

18.80

「三無數劫至一一同彼」者，此即第二明逢佛名字。如文可知。若依《大智度論》，正法五百年。此文千年，豈不相違？解云：依《善見律》，度尼故減五百年，以行八敬故還得五百年。彼論約初減時，故言五百；此論據後，故說一千。又真諦云：「佛涅槃後，經今一千二百六十五年。」

Regarding "Over the three incalculable eons ... each was identical to that": this is the second part, clarifying the names of the buddhas encountered. It can be understood from the text. If one relies on the *Mahāprajñāpāramitopadeśa*, the True Dharma lasts five hundred years. Does this text's 'one thousand years' not contradict that? The explanation is: According to the *Samantapāsādikā*, ordaining nuns decreased it by five hundred years, but practicing the Eight Weighty Rules restored five hundred years. That treatise refers to the initial decrease, hence it says five hundred; this treatise relies on the subsequent state, hence it says one thousand. Furthermore, Paramārtha says: 'After the Buddha's nirvāṇa, it has now been one thousand two hundred and sixty-five years.'
