Yonisomanasikārasampadā sutta: Accomplishment in Rational Application of Mind (1st)

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

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