The Third Discourse about Koṭṭhika
135.
The same source.
Seated to one side, the Venerable Sāriputta said this to the Venerable Mahākoṭṭhika:
"'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 matter, does not understand the origin of matter, does not understand the cessation of matter, does not understand the practice leading to the cessation of matter. Does not understand feeling... etc. perception... activities... does not understand consciousness, does not understand the origin of consciousness, does not understand the cessation of consciousness, does not understand the practice leading to the cessation of 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 matter, understands the origin of matter, understands the cessation of matter, understands the practice leading to the cessation of matter. Feeling... perception... activities... understands consciousness, understands the origin of consciousness, understands the cessation of consciousness, understands the practice leading to the cessation of consciousness. This is called, friend, true knowledge; and to this extent one is gone to true knowledge." The tenth.
