The food of those other persons who have been successively enumerated as such whose food must not be eaten, the wise declare (to be as impure as) skin, bones, and hair.
If he has unwittingly eaten the food of one of those, (he must) fast for three days; if he has eaten it intentionally, or (has swallowed) semen, ordure, or urine, he must perform a Krikkhra penance.
A Brahmana who knows (the law) must not eat cooked food (given) by a Sudra who performs no Sraddhas; but, on failure of (other) means of subsistence, he may accept raw (grain), sufficient for one night (and day).
The gods, having considered (the respective merits) of a niggardly Srotriya and of a liberal usurer, declared the food of both to be equal (in quality).
The Lord of created beings (Pragapati) came and spake to them, ’Do not make that equal, which is unequal. The food of that liberal (usurer) is purified by faith; (that of the) of the) other (man) is defiled by a want of faith.’
