Okay you've got to admit it--most people don't have one of these in their front yard. It's about 45-50 feet across and is called a "Modifed Chartres" labyrinth. In other words, it's in the style of the one in Chartres Cathedral in France, which was built around 1200 or so.
Why a labyrinth? The idea is this: many of us struggle to sit down and pray or meditate--involving the body can help us center. As you walk toward the center you empty yourself of some concerns. In the center you pause to pnder before making your way out.
This is not a maze! You don't have to make any decisions except the one to enter and walk it.
