8 Keep the flesh under by fastings and by abstinence from meat and drink, so far as health allows. When any one is not able to fast, let her not, unless she be ill, take any nourishment except at the customary hour of repast. From the time of your coming to table until you rise from it, listen without noise and wrangling to whatever may be in course read to you; let not your mouths alone be exercised in receiving food, let your ears be also occupied in receiving the word of God.
