Indriya vibhanga Sutta
Indriya-vibhanga Sutta: Analysis of the Mental Faculties translated from the Pali by Thanissaro Bhikkhu
"Monks, there are these five faculties. Which five? The faculty of conviction, the faculty of persistence, the faculty of mindfulness, the faculty of concentration, the faculty of discernment.
"Now what is the faculty of conviction? There is the case where a monk, a disciple of the noble ones, has conviction, is convinced of the Tathagata's Awakening: 'Indeed, the Blessed One is worthy and rightly self-awakened, consummate in knowledge & conduct, well-gone, an expert with regard to the world, unexcelled as a trainer for those people fit to be tamed, the Teacher of divine & human beings, awakened, blessed.' This is called the faculty of conviction.
"And what is the faculty of persistence? There is the case where a monk, a disciple of the noble ones, keeps his persistence aroused for abandoning unskillful mental qualities and taking on skillful mental qualities. He is steadfast, solid in his effort, not shirking his duties with regard to skillful mental qualities. He generates desire, endeavors, arouses persistence, upholds & exerts his intent for the sake of the non-arising of evil, unskillful qualities that have not yet arisen... for the sake of the abandoning of evil, unskillful qualities that have arisen... for the sake of the arising of skillful qualities that have not yet arisen... [and] for the maintenance, non-confusion, increase, plenitude, development, & culmination of skillful qualities that have arisen. This is called the faculty of persistence.
"And what is the faculty of mindfulness? There is the case where a monk, a disciple of the noble ones, is mindful, highly meticulous, remembering & able to call to mind even things that were done & said long ago. He remains focused on the body in & of itself ardent, alert, & mindful putting aside greed & distress with reference to the world. He remains focused on feelings in & of themselves... the mind in & of itself... mental qualities in & of themselves ardent, alert, & mindful putting aside greed & distress with reference to the world. This is called the faculty of mindfulness.
"And what is the faculty of concentration? There is the case where a monk, a disciple of the noble ones, making it his object to let go, attains concentration, attains singleness of mind. Quite withdrawn from sensuality, withdrawn from unskillful mental qualities, he enters & remains in the first jhana: rapture & pleasure born from withdrawal, accompanied by directed thought & evaluation. With the stilling of directed thoughts & evaluations, he enters & remains in the second jhana: rapture & pleasure born of composure, unification of awareness free from directed thought & evaluation internal assurance. With the fading of rapture, he remains equanimous, mindful, & alert, and senses pleasure with the body. He enters & remains in the third jhana, of which the Noble Ones declare, 'Equanimous & mindful, he has a pleasant abiding.' With the abandoning of pleasure & pain as with the earlier disappearance of elation & distress he enters & remains in the fourth jhana: purity of equanimity & mindfulness, neither pleasure nor pain. This is called the faculty of concentration.
"And what is the faculty of discernment? There is the case where a monk, a disciple of the noble ones, is discerning, endowed with discernment of arising & passing away noble, penetrating, leading to the right ending of stress. He discerns, as it has come to be: 'This is stress... This is the origination of stress... This is the cessation of stress... This is the path of practice leading to the cessation of stress.' This is called the faculty of discernment.
"These are the five faculties."
