Dutiyaassādasutta

Bārāṇasiyaṁ viharanti isipatane migadāye …pe… “‘vijja, vijjā’ti, āvuso sāriputta, vuccati. Katamā nu kho, āvuso, vijjā; kittāvatā ca vijjāgato hotī”ti?

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

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

“Reverend, a learned noble disciple truly understands 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.”
