The idol of Sri Kalinga Narthana Perumal within the inner sanctuary of the temple is about 2.5 ft high. Lord Krishna, portrayed as a five-year-old boy, is seen dancing with His left foot on the serpent's head and his right leg in the air. Krishna is depicted holding the tail of the serpent with His left hand and showing Abhaya Mudra with His right hand. It is so intricately sculpted that one can insert a thin piece of paper between the Lord's left leg and the head of the serpent. According to the temple Bhattacharya, the beauty is that the weight of the Lord's body rests on the left hand that holds the serpent's tail. One can also see the scars on the right leg of Lord Krishna formed due to the violent beating from Kalinga's tail.
