2.449

翻欲邪行中，盡壽行故久遠行故者，初是聲聞戒後是菩薩戒。諍處雪故名清等者，於欲邪行中濫招誹謗於理得雪名清，實無違犯名淨。

In reversing sexual misconduct, 'practicing for one's whole life, practicing for a long duration': the former is the śrāvaka precept and the latter is the bodhisattva precept. 'Because points of dispute are cleared, it is called pure' and so forth: in sexual misconduct, when one falsely incurs slander and is cleared in accord with reason, it is called spotless; having genuinely committed no violation is called pure.
