"A labyrinth is a single winding path that takes one to a center place and back out again. It is not a path or maze, nor does it have multiple paths or dead ends. Labyrinths have been used by many cultures for thousands of years. Walking a labyrinth can foster meditation, contemplation, and relaxation. There is no right or wrong way to walk a labyrinth. Begin at the outermost edge and follow the path to the center. At the center you may wish to take a moment to reflect. To complete the journey, retrace the path from the center outward." - "Scott Street Labyrinth", engraved on the wall at Duboce Park in San Francisco, CA
