A labyrinth is an archetype with which we can have a direct experience. We can walk it. It is a metaphor for life's journey. It is a symbol that creates a sacred space and place and takes us out of our ego to "That Which Is Within."
Labyrinths and mazes have often been confused. When most people hear of a labyrinth they think of a maze. A labyrinth is not a maze. A maze is like a puzzle to be solved. It has twists, turns, and blind alleys. It is a left brain task that requires logical, sequential, analytical activity to find the correct path into the maze and out.
A labyrinth has only one path. It is unicursal. The way in is the way out. There are no blind alleys. The path leads you on a circuitous path to the center and out again.
A labyrinth is a right brain task. It involves intuition, creativity, and imagery. With a maze many choices must be made and an active mind is needed to solve the problem of finding the center. With a labyrinth there is only one choice to be made. The choice is to enter or not. A more passive, receptive mindset is needed. The choice is whether or not to walk a spiritual path.
At its most basic level the labyrinth is a metaphor for the journey to the center of your deepest self and back out into the world with a broadened understanding of who you are.
