In vedic and puranic literature Panchagni has been mentioned as a methodology used for performing severe austerities. There are many instances of penance or tapas for thousands of years, performed by different celestial beings including Kubera, Parvati and asuras such as Mahisha and Tarakasura, by standing or sitting in the midst of five sets of fires called Panchaagni.
