Kumbh Mela or Kumbha Mela is a major pilgrimage and festival in Hinduism, On February 4, 2019, Kumbh Mela witnessed the largest public gathering. It is celebrated in a cycle of approximately 12 years, to celebrate every revolution Brihaspati (Jupiter) completes, at four river-bank pilgrimage sites: Prayagraj, Haridwar (Ganges), Nashik (Godavari), and Ujjain (Shipra). The festival is marked by a ritual dip in the waters, but it is also a celebration of community commerce with numerous fairs, education, religious discourses by saints, mass gatherings of monks, and entertainment. The seekers believe that bathing in these rivers is a means to prāyaścitta for past mistakes, and that it cleanses them of their sins.
