Accomplishment in Rational Application of Mind (1st)

“Bhikkhus, the dawn is the forerunner and precursor of the sunrise. In the same way accomplishment in rational application of mind is the forerunner and precursor of the noble eightfold path for a bhikkhu. A bhikkhu accomplished in rational application of mind can expect to develop and cultivate the noble eightfold path.

And how does a bhikkhu accomplished in rational application of mind develop and cultivate the noble eightfold path? It’s when a bhikkhu develops right view, right thought, right speech, right action, right livelihood, right effort, right mindfulness, and right samādhi, which rely on seclusion, fading away, and cessation, and ripen as letting go. That’s how a bhikkhu accomplished in rational application of mind develops and cultivates the noble eightfold path.”
