Why Panchmukhi ? : Hanuman entered pathala loka in search of Rama and Lakshmana, He found that life of Ahiravana was hidden in the five lamps which were placed in different directions. He could be killed only by extinguishing all five lamps the same time. To accomplish this Hanuman had to take the form of Panchamukha Hanuman. This form of Hanuman has five faces. Hayagriva, Narasimha, Garuda and Varaha are the four other faces along with Hanuman's face. Hanuman using the five faces in different directions blows air to extinguish the lamps there by killing Ahiravana.
