律戒本疏 1.63

1.63

十何用半月說此雜碎戒為　五篇和合名為雜也。闡陀比丘惡姓恨戾。有過不改。聞悔喻甚聞人傳時便發慢言。何用半月說此戒。為生說此戒故。令人悔惱。壞其善心。憂煎內熟。愁苦無歡。盛欲返戒。戒為道根。眾聖所重。五篇之文出自佛口。若輕戒者則輕三寶。凡輕呵經律及餘隨律經悉犯此戒。戒是沙門法。輕戒毀禁則非沙門。故輕戒經一一語犯墮。輕餘經一一語犯突。

Tenth: 'What is the use of speaking these trifling precepts every half-month?'—The joining together of the five classes is called 'trifling'. The monk Channa was ill-natured and obstinate, having faults and not reforming. Hearing of repentance, his resentment worsened; hearing people recite them, he thereupon spoke arrogant words: 'What is the use of speaking these precepts every half-month? It is just that by speaking these precepts, it makes people feel remorse and affliction, ruins their good intentions, burns and boils them within with anxiety, leaves them sad, suffering, and without joy, so that they strongly desire to return the precepts.' Precepts are the root of the Path, revered by all the noble ones. The texts of the five classes came from the Buddha's own mouth. If one disparages the precepts, one disparages the Three Jewels. Generally, disparaging or scolding the sūtras, the Vinaya, or other texts associated with the Vinaya all incur this precept. The precepts are the monastic norms; disparaging the precepts and ruining the prohibitions means one is not a śramaṇa. Therefore, disparaging the precept sūtra, for each word it is a pāyattika; disparaging other sūtras, for each word it is a duṣkṛta.
