Mahakumbh, also known as Kumbh Mela, is one of the world's largest and most significant religious gatherings. It is a festival celebrated by millions of Hindus, where devotees come together to take a holy dip in sacred rivers. The event is believed to cleanse the soul and wash away sins. The Kumbh Mela occurs every three years at four locations: Haridwar, Allahabad (Prayagraj), Nashik, and Ujjain. However, the Mahakumbh occurs every twelve years at one of these locations, making it a grander and more significant event.
