Abstaining from all food and subsisting only upon water for three nights, and sleeping for the same for the same time upon the naked earth, one should make gifts of kine to Brahmanas after having pleased them with other presents. Such kine, freed from every vice, should, at the same time, be accompained by healthy calves. Having made the gift, the giver should live for the next three days successively on food consisting only of the products of the cow.
