McMillen, Joan (1989.) Remembering the Way. Ceremony in Honor of the Labyrinth at Chartres. Menlo Park, CA, Joan Marie McMillen.
"To enter a labyrinth is to step into a rite almost as old as the human race. In the 12th century, a beautiful mandala-like version of tits ancient pattern was laid in the stone floor of the great Cathedral at Chartres. Pilgrims came from all over the Western world to walk it, asking for both physical healing and birth into the spirit-filled life that is our deepest dream. Remembering the Way is a new expression of this ancient ritual. Here are songs that lead us into the labyrinth, along the winding way to the mysterious Center and out again. Come. Join the dance." Joan McMillen.
