It is said that Lord Hanuman appeared in a Panchmukhi avatar to kill Ahiravana, the rakshasa ruler of Patala. The five faces of Panchmukhi Hanuman are of Lord Hanuman, Lord Garuda, Lord Narasimha, Lord Hayagriva and Lord Adivaraha. If one keeps the idol of Panchmukhi Hanuman idol at home, one can get rid of Vastu-related issues.
