The Buddha explains the importance of accomplishment in wise attention in the development and cultivation of the noble eightfold path.
Yonisomanasikārasampadā sutta - Accomplishment in Wise Attention
"Bhikkhus, just as the dawn precedes and predicts the rising of the sun, so too does accomplishment in wise attention precede and predict the arising of the noble eightfold path for a bhikkhu. For a bhikkhu accomplished in wise attention and careful attending, it is expected that he will develop and extensively cultivate the noble eightfold path.
And how, bhikkhus, does a bhikkhu accomplished in careful attention develop and extensively cultivate the noble eightfold path? Here, bhikkhus, a bhikkhu develops right view dependent on seclusion, supported by dispassion, based on ending, culminating in complete relinquishment; similarly he develops right intention, right speech, right action, right livelihood, right effort, right mindfulness, and right collectedness, dependent on seclusion, supported by dispassion, based on ending, culminating in complete relinquishment. Thus indeed, bhikkhus, a bhikkhu accomplished in wise attention and careful attending develops and extensively cultivates the noble eightfold path."
