大方便佛報恩經 6.71

6.71

「此二篇戒，最是重者。一戒若犯，永不起二。雖起難起，若波利婆沙、摩那埵，二十眾中而後出罪。若難持而能持者，餘篇易持戒，不須說也，是故但說二篇，不說餘篇。」

“These two classes of precepts are the gravest. If one violates one precept [of the former], it will never arise a second time. Even if it could arise, it is difficult to restore: through parivāsa and mānatva, one is purified of the offense only within an assembly of twenty monks. If one is able to uphold what is difficult to uphold, the remaining classes of precepts are easy to uphold and need not be mentioned; therefore only the two classes are spoken of, and the remaining classes are not spoken of.”
