“Bhikkhus, suppose there is a guest house. People come from the east, west, north, and south and lodge there; khattiyas, brahmins, vessas, and suddas come and lodge there. So too, when a bhikkhu develops and cultivates the Noble Eightfold Path, he fully understands by direct knowledge those things that are to be fully understood by direct knowledge; he abandons by direct knowledge those things that are to be abandoned by direct knowledge; he realizes by direct knowledge those things that are to be realized by direct knowledge; he develops by direct knowledge those things that are to be developed by direct knowledge.

“And what, bhikkhus, are the things to be fully understood by direct knowledge? It should be said: the five aggregates subject to clinging. What five? The form aggregate subject to clinging, the feeling aggregate subject to clinging, the perception aggregate subject to clinging, the volitional formations aggregate subject to clinging, the consciousness aggregate subject to clinging. These are the things to be fully understood by direct knowledge.

“And what, bhikkhus, are the things to be abandoned by direct knowledge? Ignorance and craving for existence. These are the things to be abandoned by direct knowledge.

“And what, bhikkhus, are the things to be realized by direct knowledge? True knowledge and liberation. These are the things to be realized by direct knowledge.

“And what, bhikkhus, are the things to be developed by direct knowledge? Serenity and insight. These are the things to be developed by direct knowledge.

“And how is it, bhikkhus, that when a bhikkhu develops and cultivates the Noble Eightfold Path, he fully understands by direct knowledge those things that are to be fully understood by direct knowledge; he abandons by direct knowledge those things that are to be abandoned by direct knowledge; he realizes by direct knowledge those things that are to be realized by direct knowledge; he develops by direct knowledge those things that are to be developed by direct knowledge?

Here, bhikkhus, a bhikkhu develops right view, which is based upon seclusion, dispassion, and cessation, maturing in release.

He develops right intention, which is based upon seclusion, dispassion, and cessation, maturing in release.

He develops right speech, which is based upon seclusion, dispassion, and cessation, maturing in release.

He develops right action, which is based upon seclusion, dispassion, and cessation, maturing in release.

He develops right livelihood, which is based upon seclusion, dispassion, and cessation, maturing in release.

He develops right effort, which is based upon seclusion, dispassion, and cessation, maturing in release.

He develops right mindfulness, which is based upon seclusion, dispassion, and cessation, maturing in release.

He develops right concentration, which is based upon seclusion, dispassion, and cessation, maturing in release.

It is in this way, bhikkhus, that a bhikkhu develops and cultivates the Noble Eightfold Path so that he fully understands by direct knowledge those things that are to be fully understood by direct knowledge; he abandons by direct knowledge those things that are to be abandoned by direct knowledge; he realizes by direct knowledge those things that are to be realized by direct knowledge; he develops by direct knowledge those things that are to be developed by direct knowledge.”
