You only have to enter and follow the path. However, your walk can encompass a variety of attitudes. It may be joyous or somber. It might be thoughtful or prayerful. You may use it as a walking meditation.
Adults are often serious in the labyrinth.
Children most often run in and out as fast as they can in a playful manner. When you walk a labyrinth choose your attitude. From time to time choose a different attitude. Make it serious, prayerful, or playful. Play music or sing.
