Dutiyasamudaya sutta: Origin (2nd)

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?”

“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.”
