Dutiyasamudayasutta

Bārāṇasiyaṁ viharanti isipatane migadāye …pe… ekamantaṁ nisinno kho āyasmā mahākoṭṭhiko āyasmantaṁ sāriputtaṁ etadavoca: “‘vijjā, vijjā’ti, āvuso sāriputta, vuccati. Katamā nu kho, āvuso, vijjā; kittāvatā ca vijjāgato hotī”ti?

At Varanasi. Mahākoṭṭhita said to Sāriputta: “Reverend Sāriputta, they speak of this thing called ‘knowledge’. What is knowledge? And how is a knowing one defined?”

“Idhāvuso, sutavā ariyasāvako rūpassa samudayañca atthaṅgamañca assādañca ādīnavañca nissaraṇañca yathābhūtaṁ pajānāti. Vedanāya …pe… saññāya … saṅkhārānaṁ … viññāṇassa samudayañca atthaṅgamañca assādañca ādīnavañca nissaraṇañca yathābhūtaṁ pajānāti. Ayaṁ vuccatāvuso, vijjā; ettāvatā ca vijjāgato hotī”ti. Sattamaṁ.

“Reverend, a learned noble disciple truly understands the origin, the disappearance, the gratification, the drawback, and the escape when it comes to form, feeling, perception, choices, and consciousness. This is called knowledge. And this is how a knowing one is defined.”
