[738] At that time the Buddha, the Blessed One, was dwelling at Sāvatthī, in Jeta's Grove, in Anāthapiṇḍika's park. Now at that time a certain bhikkhu was bathing in the river Aciravatī. A certain brahmin, too, having set down a bag of five hundred on the bank, bathed in the river Aciravatī and, having forgotten it, went away. Then that bhikkhu took it, thinking, "Let this bag of that brahmin not be lost." Then that brahmin, remembering, ran back in haste and said to that bhikkhu: "Sir, might you have seen my bag?" "Here, brahmin," he said, and gave it to him.
Then it occurred to that brahmin: "By what stratagem might I avoid giving this bhikkhu a full-bowl reward (puṇṇapatta)?" Saying, "Sir, it was not five hundred that was mine — a thousand was mine!" he thus harassed him and then let him go. Then that bhikkhu, having gone to the monastery, informed the bhikkhus of this matter.
Those bhikkhus who were of few wishes … they took offense, criticized, and spread it about, saying: "How indeed can a bhikkhu pick up a treasure?" …
"Is it true, as they say, bhikkhu, that you picked up a treasure?"
"It is true, Blessed One."
The Buddha, the Blessed One, rebuked him: "How indeed can you, foolish man, pick up a treasure? This, foolish man, is neither for the confidence of those without confidence, nor for the increase of those who have confidence …"
"And thus, bhikkhus, you should recite this training rule (sikkhāpada):
"Should any bhikkhu pick up, or cause to be picked up, a treasure or what is considered a treasure, there is an offense of pācittiya."
And thus this training rule was laid down by the Blessed One for the bhikkhus.
