I walked the labyrinth in Amiens Cathedral and I thought it mirrored the experience of the Christian life pretty well. At the beginning you quickly go from the outside towards the center (God), mirroring in the initial joy and closeness you feel after initially choosing to follow God. Then the labyrinth moves away from the center, but not too far out, as the initially high fades and you learn who God is, repent of sins, learn to serve. The next stage wanders around the edges, far from the center, mirroring the "dark night of the soul" and you wonder if you're ever going to make it back to the middle. Then, suddenly, move from the outside into the endpoint in the middle.
