1"Bhikkhus, there are these three kinds of existence. What three?
Sense-sphere existence,
form-sphere existence,
formless-sphere existence.
These are the three kinds of existence.

The Noble Eightfold Path is to be developed
- for direct knowledge of these three kinds of existence,
- for the full understanding of them,
- for their utter destruction,
- for their abandoning.

What Noble Eightfold Path?
Here, bhikkhus, a bhikkhu develops right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness, right concentration,
- which is based upon seclusion, dispassion, and cessation, maturing in release;
- which has as its final goal the removal of lust, the removal of hatred, the removal of delusion;
- which has the Deathless as its ground, the Deathless as its destination, the Deathless as its final goal;
- which slants, slopes, and inclines towards Nibbāna.

This Noble Eightfold Path is to be developed
- for direct knowledge of these three kinds of existence,
- for the full understanding of them,
- for their utter destruction,
- for their abandoning."

This sutta may be fully expanded in accordance with the fourfold method employed in SN45.161.
