Saw this while walking the labyrinth.
"The labyrinth is an ancient symbol of wholeness and a metaphor for life’s journey. While labyrinths date back more than 4000 years, the medieval labyrinth dates to the Middle Ages when medieval pilgrims, unable to fulfill their desire to make pilgrimages to Jerusalem, went instead to many pilgrimage sites throughout Europe. They often convened at a labyrinth formed of stone in the floor of a Gothic cathedral. Within the safety of the cathedral, they would walk the labyrinth, symbolic of their life’s journey to God.
At the center of the labyrinth is a circular sculpture created by stonemason Dan Sieracki. The circle is a symbol of eternity and the fullness of life to which God calls each of us. This empty circle at the labyrinth’s center reminds us to empty ourselves so that we might be filled with Christ’s peace." Holy Family Passionist Retreat Center
