[267] "Kassapa, even if one is a naked ascetic (acelaka), of loose conduct, a licker of hands … thus dwelling devoted to the practice of eating food at set intervals of even half a month — yet if this accomplishment in virtue (sīlasampadā), accomplishment in mind (cittasampadā), and accomplishment in wisdom (paññāsampadā) is undeveloped and unrealized by him, then indeed he is far from the state of an ascetic (sāmañña) and far from the state of a brahmin (brahmañña). But when, Kassapa, a bhikkhu develops a mind (citta) of loving-kindness that is without enmity and without affliction, and, through the destruction of the taints (āsava), realizes for himself with direct knowledge (abhiññā), in this very life, the taintless liberation of mind and liberation by wisdom, and having entered upon it dwells therein — this bhikkhu, Kassapa, is called an 'ascetic' and also a 'brahmin.'
"And even if, Kassapa, one is an eater of greens, an eater of millet … subsists on wild roots and fruits, feeding on fallen fruit — yet if this accomplishment in virtue, accomplishment in mind, and accomplishment in wisdom is undeveloped and unrealized by him, then indeed he is far from the state of an ascetic and far from the state of a brahmin. But when, Kassapa, a bhikkhu develops a mind of loving-kindness that is without enmity and without affliction, and, through the destruction of the taints, realizes for himself with direct knowledge, in this very life, the taintless liberation of mind and liberation by wisdom, and having entered upon it dwells therein — this bhikkhu, Kassapa, is called an 'ascetic' and also a 'brahmin.'
"And even if, Kassapa, one wears hemp cloth, wears cloth of mixed fibre … dwells devoted to the practice of descending into the water even a third time in the evening — yet if this accomplishment in virtue, accomplishment in mind, and accomplishment in wisdom is undeveloped and unrealized by him, then indeed he is far from the state of an ascetic and far from the state of a brahmin. But when, Kassapa, a bhikkhu develops a mind of loving-kindness that is without enmity and without affliction, and, through the destruction of the taints, realizes for himself with direct knowledge, in this very life, the taintless liberation of mind and liberation by wisdom, and having entered upon it dwells therein — this bhikkhu, Kassapa, is called an 'ascetic' and also a 'brahmin.'"
