The pilgrims come and go as strangers. They march like a sea of people, walking toward the spot where they take holy baths, drawn by the hope that the bathing would bring them salvation. But when they leave — believing their sins have been cleansed by the redemptive bath — they leave with one thing in common: their foreheads display a sacred stroke of color.
