四分律行事鈔資持記 3.542

3.542

《四分》。即疑惱戒不犯文，彼云犯波羅夷乃至惡說，故云吉已上也；恐妄受利，開語令知，如法懺悔。用斯自檢，寧復有人堪受施者。若但養身，此何足議；苟能反己，豈不懷慚。上引諸文，並約戒淨，復須臨境起治，方堪應供。必非此二，俱為苦因；佛語無虛，固當信奉。

The Dharmaguptaka-vinaya: this is the non-offense passage of the precept on suspecting and harassing, where it says committing from pārājika down to duṣkṛta, hence it says "from duṣkṛta on up"; fearing that they might falsely receive benefits, an exception is made to inform them so they may repent according to the Dharma. If one uses this to examine oneself, who would still be worthy to receive offerings? If one merely nourishes the body, how is this worth discussing? If one can reflect upon oneself, how could one not feel shame? The various texts cited above all rely on purity of precepts; furthermore, one must arouse counteraction when facing the object to then be worthy to receive offerings. If one lacks both of these, both become causes of suffering; the Buddha's words are not empty, and one must firmly believe and uphold them.
