四分比丘戒本疏 1.49

Question: Once the duṣkṛta of concealment has been repented, the fault of concealment should be eliminated; why is it necessary to request that it be dealt with? Answer: Although the offence of concealment in terms of bringing about retribution is eliminated through repentance, inappropriately mingling with the pure Saṃgha renders the saṃghāvaśeṣa offence grave; if this fault is not penalized, the saṃghāvaśeṣa offence cannot be removed, and therefore concealment must be dealt with. If one did not conceal it, the saṃghāvaśeṣa fault is made lighter, and therefore concealment is not dealt with.
