The labyrinth is a prayer tool, an ancient pattern found in many cultures and traditions around the world. Labyrinth designs were found on pottery, tablets and tiles dating as far back as 4000 years. Many patterns are based on spirals from nature. In Native American culture it is called the Medicine Wheel and Man in the Maze. The Celts described it as the Never Ending Circle. It is also called the Kabala in mystical Judaism. One feature they all share is that they have one path which winds in a circuitous way to the center.
Labyrinths are currently being used world-wide as a way to quiet the mind, find balance, and encourage meditation, insight and celebration. They are open to all people as a non-denominational, cross-cultural tool of well-being. They can be found in medical centers, parks, churches, schools, prisons, memorial parks and retreat centers as well as in people's backyards.
Luther College Ministries' labyrinth is based on the Chartres Labyrinth, laid in the floor of Chartres Cathedral around 1220. It is set up occasionally during the semester for meditation or chapel, as well as weekly during the month of January. See here for more information on labyrinths.
The labyrinth is not a maze. There are no tricks to it and no dead ends. It has a single circuitous path that winds into the center. The person walking it uses the same path to return and the entrance then becomes the exit. The path is in full view, which allows a person to be quiet and focus internally.
When walking a labyrinth, quiet your mind and become aware of your breath. Allow yourself to find the pace your body wants to go. The path is two ways. Those going in will meet those coming out. You may "pass" people or let others step around you. Do what feels natural.
