Christians believe that they belong to a communion of saints — a community of believers that transcends time and space. Other religious traditions emphasize the influential role of ancestors or spirit guides in people's lives. Think about the invisible presences to whom you feel connected. Dedicate one of your activities during the day to those who have gone before you and those who will come after you. For example, while grocery shopping, choose items that remind you of your ancestors and that you want to be available to future generations.
