The Labyrinth appears in many different cultures, and has been used by varrying different beleif systemes, it appears throughout Europe, the Native Amercians had thier own labyrinth patern. The Buddists use the labyrinth for a form of meditation, and even the Christains use it to be symbolic of a pilgrimige if one cannot physcialy take the journey, some Cathedrals have thier own labyrinths, they also use it as a way for one to reflect upon God.
Though the labyrinth is often mistakenly thought to be a sort of maze, there are two key differences that set them apart and make the labyrinth its own thing. Unlike a maze in which a person is to enter into one end and come out another end, and is made of of varrious false turns and dead ends, the labyrinth has but one way path, which takes the traverse to its center, and then winds them back out the same way they came in.
Often the center of a labyrinth, particuarly within the Pagan Labyrinth, the center of it will be a place where one will leave offerings, it can be anything from a stone, to a coin, a personal item, etc...
The labyrinth does offer a place for one to reflect upon thier lifes, and upon the Goddess or creative force of thier choice, and to communitcate with the divine, as well as to clear the mind and find a sense of peace and clairty.
A person can enter into the labyrinth for many reasons, if they feel they need to reconnect with the Diety, if they are stressed and need to clense themselves it can be very medatative, or of it one is seaking answeres it can be a way to gain understanding of a situation, or just to relfect upon thier life and everything they have to thank the Diety for everything good within thier life.
One thing that should be noted, is the simillarity of the pattern of the labyrinth to the symbol of the spiral.
