"Bhikkhus, just as in the autumn, when the sky is clear and cloudless, the sun, ascending in the sky, dispels all darkness from space as it shines and beams and radiates,[n.38] The similes of SN45.141–47 are also at SN22:102. sn.v.45

so too whatever wholesome states there are, they are all rooted in diligence, converge upon diligence, and diligence is declared to be the chief among them.

When a bhikkhu is diligent, it is to be expected that he will develop and cultivate the Noble Eightfold Path.

And how, bhikkhus, does a bhikkhu who is diligent develop and cultivate the 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.

It is in this way, bhikkhus, that a bhikkhu who is diligent develops and cultivates the Noble Eightfold Path."
