[248] And how, bhikkhus, does a bhikkhu who is heedful (appamatta) develop the noble eightfold path (ariya aṭṭhaṅgika magga), how does he cultivate the noble eightfold path? Here, bhikkhus, a bhikkhu develops right view (sammādiṭṭhi), which culminates in the removal of lust (rāga), culminates in the removal of hatred, culminates in the removal of delusion … he develops right concentration (sammāsamādhi), which culminates in the removal of lust, culminates in the removal of hatred, culminates in the removal of delusion. It is in this way, bhikkhus, that a bhikkhu who is heedful develops the noble eightfold path, cultivates the noble eightfold path.
