[504] At that time the Buddha, the Blessed One, was dwelling at Sāvatthī, in Jeta's Grove, Anāthapiṇḍika's monastery. Now at that time two bhikkhus were traveling along the highway through the Kosalan country to Sāvatthī. One bhikkhu engaged in improper conduct (anācāra). The second bhikkhu said to that bhikkhu: "Friend, do not do such a thing; this is not proper." The other harbored a grudge against him.
Then those bhikkhus arrived at Sāvatthī. Now at that time in Sāvatthī there was a meal for the Saṅgha given by a certain guild. The second bhikkhu had eaten and had refused further food (pavārita). The bhikkhu who harbored the grudge, having gone to a family of his relatives and obtained almsfood, approached that bhikkhu; and having approached, he said to that bhikkhu: "Eat, friend."
"Enough, friend; I am full."
"Friend, the almsfood is fine; eat."
Then that bhikkhu, being pressed by that bhikkhu, ate that almsfood. The bhikkhu who harbored the grudge said to that bhikkhu: "So, friend, you think that I am one to be admonished by you — you who, having eaten and refused further food, eat food that is not left over (anatiritta)?"
"Friend, should it not have been told?"
"Friend, should it not have been asked?"
Then that bhikkhu informed the bhikkhus of this matter. Those bhikkhus who were of few wishes … They criticized, deplored, and complained: "How indeed can a bhikkhu invite a bhikkhu who has eaten and refused further food, presenting him with food that is not left over?" …
"Is it true, as they say, bhikkhu, that you invited a bhikkhu who had eaten and refused further food, presenting him with food that was not left over?"
"It is true, Blessed One."
The Buddha, the Blessed One, rebuked him: "How indeed can you, foolish man, invite a bhikkhu who has eaten and refused further food, presenting him with food that is not left over? This, foolish man, is not for the confidence of those without confidence, nor for the increase of those already confident. …
"And thus, bhikkhus, you should recite this training rule:
"Whatever bhikkhu, knowing, and seeking an occasion to find fault, should invite a bhikkhu who has eaten and refused further food, presenting him with hard food or soft food that is not left over, saying, 'Come, bhikkhu, chew or eat' — when he has eaten, it is an offense of pācittiya."
