三彌勒經疏 1.191

1.191

經曰「彌勒如來」以下，第四答幾時住問。此中二：初立戒時、後住法時。是初也。無瑕穢者，清淨無犯。若《增一經》云「毘婆尸佛百年清淨無犯，釋迦佛十二年無瑕」也。

From the sūtra's words, "Maitreya Tathāgata..." onward is the fourth [section], answering the question of how long [the Dharma] abides. Within this there are two [parts]: first, the time of establishing the precepts; second, the time the Dharma abides. This is the first. "Free of flaw and defilement" means pure and without transgression. As the *Ekottarika Āgama* says: "For Vipaśyin Buddha, for one hundred years it was pure and without transgression; for Śākyamuni Buddha, for twelve years it was free of flaw."
