[500] Bhikkhus, these seven factors of awakening (bojjhaṅga) are non-obstructing (anāvaraṇā), non-hindering (anīvaraṇā), not overgrowths of the mind (citta); when developed and cultivated, they lead to the realization of the fruit of true knowledge and liberation (vijjā-vimutti). What seven? The mindfulness factor of awakening, bhikkhus, is non-obstructing, non-hindering, not an overgrowth of the mind; when developed and cultivated, it leads to the realization of the fruit of true knowledge and liberation. … equanimity … These indeed, bhikkhus, are the seven factors of awakening that are non-obstructing, non-hindering, not overgrowths of the mind; when developed and cultivated, they lead to the realization of the fruit of true knowledge and liberation.
