or Kumbha Mela
is a major pilgrimage and festival in Hinduism. It is celebrated in a cycle of approximately 12 years, to celebrate every revolution Brihaspati (Jupiter) completes, at four river-bank pilgrimage sites: the Allahabad (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 feedings of monks or the poor, and entertainment spectacle. The seekers believe that bathing in these rivers is a means to prāyaścitta for past mistakes, and that it cleanses them of their sins.
