[411] What five things are of great benefit? The five factors of striving (padhāniyaṅga).
Here, friends, a bhikkhu has faith (saddhā); he places faith in the awakening of the Tathāgata thus: 'Thus indeed is that Blessed One: an arahant, perfectly self-awakened, accomplished in true knowledge (vijjā) and conduct, fortunate, knower of the world, unsurpassed trainer of persons to be tamed, teacher of gods and humans, awakened, blessed.'
He is of few afflictions and few ailments, endowed with an even digestion, neither too cool nor too hot but middling, capable of enduring striving.
He is not fraudulent, not deceitful, one who reveals himself as he really is (yathābhūta) to the Teacher or to his wise companions in the holy life.
He dwells with energy (vīriya) aroused for the abandoning of unwholesome states and for the acquisition of wholesome states; he is strong, firm in exertion, not shirking the burden with regard to wholesome states.
He is wise: endowed with wisdom directed to arising and passing away, which is noble, penetrative, and leads rightly to the complete destruction of suffering (dukkha).
These five things are of great benefit.
