Sri Kshetra Gangapur, One of the most famous Dattatreya
Temples , is associated with Sri Narasimha Sarasvati Swami, an
incarnation of Lord Dattatreya. It stands on the bank of the river Bhima in Afzalpur taluka in Gulbarga district of Karnataka. This Nirguna Math is adorned with the Nirguna Padukas. The water of the rivers Bhima and Amaraja, especially at the spot of their confluence, are considered extremely holy. " Bhima-Amarja Sangam at Gangapur is very sacred. There are Koti Theerthas there. The Aswatha Tree at Gangapur is as powerful as tha KalpaVriksha. Near the Aswatha Tree is Narasimha Teertha, and northwards to it are the PapaVinasini Teertha, Varanasi Teertha, Rudrapada Teertha, Chakra Teertha, Koti Teertha, manmadha Teertha etc. There is the Kalleshwara temple there. It is holy as Gokarna.", Sri Narasimha Saraswati lived in Gangapur continuously for a period of 24 years.
According to the book Shri GuruCharitra, Sri Narasimha Saraswati Swamihe promised that he would abide forever at Ganagapura. In the morning, he would bathe at the confluence of the Bhima and Amarja rivers. At midday, he would go through the village asking for bhiksha (alms of food), and accept pooja offerings in the form of Nirguna Paduka at the temple. Devotees believe that by bathing at the confluence, by begging (Maadhukari) from at least five houses in Ganagapura, and by offering Paduka Pooja at the temple, they can experience the living presence (darśana) of Sri Narasimha Saraswati Swami, and be freed from sins and granted wishes.
