Dutiyakoṭṭhika sutta: With Koṭṭhita (2nd)

At Varanasi.

“Reverend Koṭṭhita, they speak of this thing called ‘ignorance’. What is ignorance? And how is an ignoramus defined?”

“Reverend, an unlearned ordinary person doesn’t truly understand the origin, the disappearance, the gratification, the drawback, and the escape when it comes to form, feeling, perception, choices, and consciousness.

This is called ignorance. And this is how an ignoramus is defined.”

When he said this, Venerable Sāriputta said to him:

“Reverend Koṭṭhita, 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.”
