The Maha Kumbh Mela is the world’s largest spiritual gathering, celebrated once every 144 years in Prayagraj, at the confluence of the Ganga, Yamuna, and Saraswati rivers. This rare event follows 12 cycles of the 12-year Purna Kumbh Mela and attracts millions of pilgrims for sacred rituals, holy baths, and devotional celebrations.
