Factors (for Exertion)
Aṅga Sutta (AN 5:53)
“These are the five factors for exertion. Which five?
“There is the case where a monk has conviction, is convinced of the Tathāgata’s awakening: ‘Indeed, the Blessed One is worthy & rightly self-awakened, consummate in clear-knowing & conduct, well-gone, an expert with regard to the cosmos, unexcelled trainer of people fit to be tamed, teacher of devas & human beings, awakened, blessed.’
“He is free from illness & discomfort, endowed with good digestion—not too cold, not too hot, of moderate strength—fit for exertion.
“He is neither fraudulent nor deceitful. He declares himself to the Teacher or to his observant companions in the holy life in line with what he actually is.
“He keeps his persistence aroused for abandoning unskillful qualities and taking on skillful qualities. He is steadfast, solid in his effort, not shirking his duties with regard to skillful qualities.
“He is discerning, endowed with discernment leading to the arising of the goal—noble, penetrating, leading to the right ending of stress.
“These are the five factors for exertion.”
