Go on a fast. If you are inexperienced in this practice, begin with a one-day fast. Eat only fruits or vegetables and drink at least eight glasses of water. Or skip a meal a day for one week. Use the time you would have spent preparing and eating food for quiet reflection on the experience of being hungry. Feel compassion for the millions of people around the world who do not have enough to eat.
Volunteer to serve meals at a soup kitchen, to carry meals to shut-ins, to read to people in the hospital, or to do any other activity that puts you close to suffering.
