Manu has declared that the flesh (of an animal) killed by dogs is pure, likewise (that) of a (beast) slain by carnivorous (animals) or by men of low caste (Dasyu), such as Kandalas.
All those cavities (of the body) which lie above the navel are pure, (but) those which are below the navel are impure, as well as excretions that fall from the body.
In order to cleanse (the organs) by which urine and faeces are ejected, earth and water must be used, as they may be required, likewise in removing the (remaining ones among) twelve impurities of the body.
Oily exudations, semen, blood, (the fatty substance of the) brain, urine, faeces, the mucus of the nose, ear-wax, phlegm, tears, the rheum of the eyes, and sweat are the twelve impurities of human (bodies).
