[577] "Great king, there are these five factors of striving (padhāniyaṅga). What five?
Here, great king, a bhikkhu has faith (saddhā); he places faith in the awakening of the Tathāgata thus: 'Thus indeed is that Blessed One: an arahant, a fully awakened one, 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, possessed of an even digestion, neither too cool nor too hot, but middling, fit for striving.
He is not deceitful and not fraudulent; he reveals himself as he really is (yathābhūta) to the Teacher or to wise companions in the holy life.
He dwells with energy (vīriya) aroused for the abandoning of unwholesome dhammas and for the taking on of wholesome dhammas; he is strong, of firm exertion, not laying down the burden with regard to wholesome dhammas.
He is wise, possessed of the wisdom that discerns arising and passing away, which is noble and penetrative, leading rightly to the destruction of suffering (dukkha).
These, great king, are the five factors of striving. Great king, there are these four castes: khattiyas, brahmins, vessas, and suddas. If those four were possessed of these five factors of striving, that would be for their welfare and happiness for a long time."
