[56] At Sāvatthī. … Then a certain bhikkhu approached the Blessed One; having approached, he paid homage to the Blessed One and sat down to one side. Seated to one side, that bhikkhu said this to the Blessed One: "Venerable sir, how does one know, how does one see, so that ignorance (avijjā) is abandoned and true knowledge (vijjā) arises?"
"Bhikkhu, for one who knows and sees the eye as impermanent, ignorance is abandoned and true knowledge arises. For one who knows and sees forms as impermanent, ignorance is abandoned and true knowledge arises. For one who knows and sees as impermanent eye-consciousness, eye-contact, and whatever is felt that arises with eye-contact as condition—whether pleasant, painful, or neither-painful-nor-pleasant—ignorance is abandoned and true knowledge arises. For one who knows and sees as impermanent the ear, the nose, the tongue, the body, the mind, ignorance is abandoned and true knowledge arises. For one who knows and sees as impermanent mental phenomena (dhammā), mind-consciousness, mind-contact, and whatever is felt that arises with mind-contact as condition—whether pleasant, painful, or neither-painful-nor-pleasant—ignorance is abandoned and true knowledge arises. Bhikkhu, for one who knows thus, for one who sees thus, ignorance is abandoned and true knowledge arises."
