Pāli · Sutta Piṭaka (Pāli, Mahāsaṅgīti)“Idhāvuso sāriputta, bhikkhu dhammaṁ pariyāpuṇāti— suttaṁ geyyaṁ veyyākaraṇaṁ gāthaṁ udānaṁ itivuttakaṁ jātakaṁ abbhutadhammaṁ vedallaṁ.
So yathāsutaṁ yathāpariyattaṁ dhammaṁ vitthārena paresaṁ deseti, yathāsutaṁ yathāpariyattaṁ dhammaṁ vitthārena paresaṁ vāceti, yathāsutaṁ yathāpariyattaṁ dhammaṁ vitthārena sajjhāyaṁ karoti, yathāsutaṁ yathāpariyattaṁ dhammaṁ cetasā anuvitakketi anuvicāreti manasānupekkhati.
Yasmiṁ āvāse therā bhikkhū viharanti bahussutā āgatāgamā dhammadharā vinayadharā mātikādharā tasmiṁ āvāse vassaṁ upeti. Te kālena kālaṁ upasaṅkamitvā paripucchati paripañhati: ‘idaṁ, bhante, kathaṁ; imassa kvattho’ti? Te tassa āyasmato avivaṭañceva vivaranti, anuttānīkatañca uttānīkaronti, anekavihitesu ca kaṅkhāṭhāniyesu dhammesu kaṅkhaṁ paṭivinodenti.
Ettāvatā kho, āvuso sāriputta, bhikkhu assutañceva dhammaṁ suṇāti, sutā cassa dhammā na sammosaṁ gacchanti, ye cassa dhammā pubbe cetasā samphuṭṭhapubbā te ca samudācaranti, aviññātañca vijānātī”ti.
English · Bhikkhu Sujato“Reverend Sāriputta, take a mendicant who memorizes the teaching— statements, mixed prose & verse, discussions, verses, inspired exclamations, legends, stories of past lives, amazing stories, and elaborations.
Then, just as they learned and memorized it, they teach others in detail, make them recite in detail, they rehearse it themselves in detail, and they think about and consider the teaching in their heart, examining it with the mind.
They enter the rains retreat in a monastery with senior mendicants who are very learned, inheritors of the heritage, who have memorized the teachings, the monastic law, and the outlines. From time to time they go up to those mendicants and ask them questions: ‘Why, sir, does it say this? What does that mean?’ Those venerables reveal what is hidden, clarify what is unclear, and dispel doubt regarding the many doubtful matters.
This is how a mendicant gets to hear a teaching they haven’t heard before. It’s how they remember those teachings they have heard. It’s how they keep exercising the teachings with which they are already familiar. And it’s how they come to understand what they haven’t understood before.”
