Every religion possesses its prescribed rites and rituals, but pilgrimage, in particular, seems to appeal to an instinctive movement of the human heart. The Latin phrase ambulare pro Deo, "to walk for God," is as valid for a Christian pilgrim setting out for Santiago de Compostela as for a Muslim drawn to the Ka'ba shrine at Mecca or a Buddhist circumambulating a stupa.
