At the confluence of these rivers, there is a very old temple of Sri Narasimha Swamy. According to the Puranas, Vyasa Bhagavan knowing the piousness of the place, meditated for a long time for the manifestation of Sri Narasimha Swamy. Commiserating at the continued penance of Vyasa Bhagavan Lord Maha Vishnu again transfigured as Narasimha Swamy and appeared to the former, with ferocious looks of a lion. Vyasa Bhagavan experienced Lord Narasimha, who was taking breath with uncontrolled anger, coming to him just after killing Hiranyakasipu. He, therefore, entreated Sri Narasimha Swamy to manifest at Wadapally in that form only. Accordingly, Sri Narasimha Swamy manifested there to bless the devotees and to alleviate their difficulties. It is believed that even now the idol breathes in and out. The temple authorities have arranged two lamps. One of the lights of the lamp used for showing the face of the Lord will be quivering to testify the fact that the Lord is taking breath and letting it out. The light of the other lamp, which is kept below remain resolutely.
