In the historic pilgrimage of Mithila state, which includes two main Dolis (Processions) or travel camps, such as the Mela, established with the name of Lord Bihari from Mithila Bihari, the city of Janakpur, which is recognized as the holy place of the Hindu religion, meaning the father-in-law's place of Lord Ram, has given additional identity to the Mithila Bihari.
