One who eats or drinks the flesh, ordure, or urine of a dog, a boar, a man, a cock or a camel must have the ceremony of putting on the sacred thread performed again. If a Somadrinking Brahmana smells alcohol from the mouth of one who has drunk it, he should drink warm water for three days or warm milk for the same period. Or, drinking warm water for three days he should live for that period upon air alone. These are the eternal injunctions prescribed for the expiation of sin, especially for a Brahmana who has perpetrated these sins through ignorance and want of judgement.
