“Bhikkhus, whatever states there are that are wholesome, partaking of the wholesome, pertaining to the wholesome, 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 seven factors of enlightenment.
“And how, bhikkhus, does a bhikkhu who is diligent develop and cultivate the seven factors of enlightenment? Here, bhikkhus, a bhikkhu develops the enlightenment factor of mindfulness … the enlightenment factor of equanimity, which is based upon seclusion, dispassion, and cessation, maturing in release. It is in this way, bhikkhus, that a bhikkhu who is diligent develops and cultivates the seven factors of enlightenment.”
