What is a Labyrinth?

What is a Labyrinth? A labyrinth is a single path or unicursal tool for personal, psychological and spiritual transformation. Labyrinths are thought to enhance right brain activity.
The Classical Seven Circuit Labyrinth in this example shows that you enter a labyrinth through the mouth and then walk on the paths or circuits. The walls keep you on the path. The goal is in the center of the labyrinth. When you reach it, you have gone half the distance – you now need to turn around and walk back out.(from the Labyrinth Society)

Labyrinths appeared as designs on pottery or basketry, as body art, and in etchings on walls of caves or churches. The Romans created many primarily decorative labyrinth designs on walls and floors in tile or mosaic. Many labyrinths set in floors or on the ground are large enough that the path can be walked. They have been used historically both in group ritual and for private meditation. (from Wikipedia)
