The Second Discourse about Koṭṭhika
134.
They were dwelling at Bārāṇasī in the Deer Park at Isipatana, etc.
"'Ignorance, ignorance', friend Koṭṭhika, is said.
What indeed, friend, is ignorance, and in what way is one gone to ignorance?"
"Here, friend, an ignorant worldling does not understand as it really is the origin, passing away, gratification, danger, and escape regarding matter. In feeling, etc. in perception, of activities... does not understand as it really is the origin, passing away, gratification, danger, and escape regarding consciousness. This is called, friend, ignorance; and to this extent one is gone to ignorance."
When this was said, the Venerable Sāriputta said this to the Venerable Mahākoṭṭhika: "'True knowledge, true knowledge', friend Koṭṭhika, is said. What indeed, friend, is true knowledge, and in what way is one gone to true knowledge?"
"Here, friend, a learned noble disciple understands as it really is the origin, passing away, gratification, danger, and escape regarding matter. In feeling, etc. in perception, of activities... understands as it really is the origin, passing away, gratification, danger, and escape regarding consciousness. This is called, friend, true knowledge; and to this extent one is gone to true knowledge." The ninth.
