It is known as the festival of lights and takes place at the Pampa River a day before Makara Sankranthi. It is believed to be the most holy spot of the pilgrimage as according to the legend, Manikanda was found on the banks of the river by the king Rajesekhara of Panthalam. Another reason for the celebration is Ayyappaa and His army came to Pampa to celebrate their victory, by lighting lamps, after destroying Udayanan. All camps and huts are decorated with lights and candles. Lamps are lit in front of irumudi’s and small boats decorated with lights are launched into the river to commemorate the victory.
