Narsinghji Temple is an ancient Hindu temple located at Prahlad Kund in the Hindaun City in the Indian state Rajasthan. According to Hindu scriptures (not mythology), lord Narsingh Ji is an avatar of Lord Vishnu. Lord Narasimha had killed the devil named Hiranya Kashyap and gave help to his son Prahlada, so this temple is lord Narsinghji’s temple. The Narsingh Ji gufa temple is 15 km far from Hindaun City and is established beside Hindaun-Karauli road. The statue of Lord Narsingh Ji is established in a cave or gufa. The cave is fulfilled with darkness and the shriddhalus are came into that cave. People who suffer from malignant spirits and black magic or spells are believed to get their relief when they make an appeal for relief to Shri Narsingh Ji Maharaj, who holds his court and awards punishment to the malignant spirits, ghosts, goblins, ghouls, and evil-eyed witches.
