The central theme of the Kumbh Mela festival in India revolves around spiritual purification and the gathering of millions of pilgrims. Celebrated at four sacred sites, this festival occurs every 12 years and is marked by the ritual bathing in holy rivers. It symbolizes the cycle of life and the quest for salvation as devotees believe that bathing in the sacred waters absolves them of sins. The festival fosters a strong sense of community and devotion, uniting people in their spiritual journeys.
