[266] When this was said, the naked ascetic (acela) Kassapa said to the Blessed One: "Friend Gotama, there are also these courses of ascetic exertion (tapopakkama) which, for those ascetics and brahmins, are reckoned as true asceticism and reckoned as true brahminhood: one goes naked, rejecting conventions, licking one's hands; one does not come when told 'Come, good sir,' one does not stand when told 'Stand, good sir'; one does not consent to food brought, nor to food prepared specially, nor to an invitation. He does not receive from the mouth of a pot, nor from the mouth of a basket; nor across a threshold, nor across a stick, nor across a pestle; nor from two people eating together; nor from a pregnant woman, nor from a woman giving suck, nor from a woman who has been with a man; nor food collected by announcement; nor where a dog is standing by; nor where flies are swarming in clusters; he takes no fish, no meat; he drinks no liquor, no wine, no fermented gruel. He is a one-house man, a one-morsel man; or a two-house man, a two-morsel man; or a seven-house man, a seven-morsel man; he sustains himself on one small offering (datti), or on two small offerings, or on seven small offerings; he takes food once a day, or once every two days, or once every seven days. Thus he dwells devoted to the practice of taking food by rotation, even up to intervals of half a month.
Friend Gotama, there are also these courses of ascetic exertion which, for those ascetics and brahmins, are reckoned as true asceticism and reckoned as true brahminhood: one feeds on greens, or feeds on millet, or feeds on wild rice, or feeds on rice-scraps (daddula), or feeds on resin, or feeds on the haṭa water-plant, or feeds on rice-bran, or feeds on rice-scum, or feeds on sesame flour, or feeds on grass, or feeds on cow-dung; he sustains himself on forest roots and fruits, eating fallen fruit.
Friend Gotama, there are these courses of ascetic exertion which, for those ascetics and brahmins, are reckoned as true asceticism and reckoned as true brahminhood: he wears hemp cloth, wears mixed-hemp cloth, wears corpse-shrouds, wears rag-robes, wears tirīṭa-bark garments, wears antelope hides, wears strips of antelope hide, wears garments of kusa grass, wears garments of bark fiber, wears garments of wood shavings, wears a blanket of human hair, wears a blanket of animal-tail hair, wears owls' wings; he is a plucker-out of hair and beard, devoted to the practice of plucking out hair and beard; he is a stander-upright, rejecting seats; he is a squatter, devoted to exertion in squatting; he is one who lies on thorns, making his bed upon thorns; he makes his bed on a plank; he makes his bed on the bare ground; he lies on one side only; he is a wearer of dust and dirt; he lives in the open air; he takes whatever resting place is spread for him; he is an eater of foul food, devoted to the practice of eating foul food; he is one who does not drink, devoted to the practice of not drinking; he dwells devoted to the practice of going down into the water to bathe three times daily, evening included."
