Thus I carry on a daily war by fasting, constantly “bringing my body into subjection,” 334 after which my pains are banished by pleasure. For hunger and thirst are actual pain. They consume and destroy like fever does, unless the medicine of food is at hand to relieve us. And since this medicine at hand comes from the comfort we receive in thy gifts (by means of which land and water and air serve our infirmity), even our calamity is called pleasure.
