Circuits refer to the number of times the path passes between the center and the outside edge.
The labyrinth is an ancient path of pilgrimage, rich with meaning. Early in the 13th century, when the Crusades made journeying to sacred destinations too dangerous, if not impossible, would-be pilgrims got creative and used this beautiful path of prayer within the safety of the church. Within the labyrinth they could take a metaphorical pilgrimage. Since that time, the uses have expanded to include a path of self-discovery, healing, contemplation and revelation.
Labyrinths have been found in multiple variations on the same theme — a single, winding path to a center point, which then returns to the outside — in many different cultures, some dating back four to five thousand years.
