For Hindu mystics and for Sufis, . . . sacred place is within themselves: their pilgrimage is a journey with no physical movement, but a personal seeking within mind and body. For others, the sacred place may have a physical existence but the journey there be symbolic, as when medieval Christian pilgrims trod the foot mazes on the floors of cathedrals known as the "Path to Jerusalem."
