Narasimha is the half man-half lion incarnation of Vishnu who vanquished Hiranyakashipu in order to protect his devotee, Prahalada.
On his appearance day (Vaishaka Shukla Chaturdashi), Hindus fast through daylight hours and perform a puja at sunset; the time at which Narasimha appeared. One of the most ferocious Vaishnava deities, he is invoked for protection and destruction of very difficult challenges. Narasimha is a popular deity in Telugu states and Odisha and Multan in W.Punjab (Pakistan) also sacred to this deity, though sadly the temple is derelict and encroached upon.
