In another incident during the war, Rama and Lakshmana are captured by the rakshasa Mahiravana brother of Ravana, who held them captive in their palace in Patala, the netherworld. Mahiravana keeps them as offerings to his deity. Searching for them, Hanuman reaches Patala. Upon entering Patala, Hanuman discovers that to kill Mahiravana, he must simultaneously extinguish five lamps burning in different directions. Hanuman assumes the Panchamukhi or five-faced form of Sri Varaha facing north, Sri Narasimha facing south, Sri Garuda facing west, Sri Hayagriva facing the sky and his own facing the east, and blows out the lamps. Hanuman then rescues Rama and Lakshmana from Mahiravana.
