Hiranyavadaipadalam

Legend says that when contemporaries objected to Hiranyavadaipadalam ("Story of Hiranyakasipu", which occurs as Vibhishana telling Ravana while warning against his false sense of invincibility), Kamban read it in front of the Narasimha Swami temple in Sri Ranganathaswamy Temple. The Swami applauded by laughing out aloud from his Sanctum Sanctora (Mettu Narasimhar Sannidhi), and this was taken as proof of approval.
