“Bhikkhus, just as various winds blow in the sky—easterly winds, westerly winds, northerly winds, southerly winds, dusty winds and dustless winds, cold winds and hot winds, gentle winds and strong winds —so too, when a bhikkhu develops and cultivates the Noble Eightfold Path, then for him the four establishments of mindfulness go to fulfilment by development; the four right strivings go to fulfilment by development; the four bases for spiritual power go to fulfilment by development; the five spiritual faculties go to fulfilment by development; the five powers go to fulfilment by development; the seven factors of enlightenment go to fulfilment by development.
“And how is this so? Here, bhikkhus, a bhikkhu develops right view … right concentration, which is based upon seclusion, dispassion, and cessation, maturing in release. It is in this way, bhikkhus, that when a bhikkhu sn.v.50 develops and cultivates the Noble Eightfold Path, then for him the four establishments of mindfulness … the seven factors of enlightenment go to fulfilment by development.”
