Located about 90 km west of Chennai and about 25 km from Arakkonam, atop a hill on a single stone is the Yoga Narasimha temple in Sholingur, also called Thiru Kadigai. There are three separate shrines of Vishnu in the form of Narasimha, Bhaktavatsala Perumal, and Hanuman. They are situated on the larger hill, at the base of the larger hill and on the smaller hill respectively. Vishnu Purana and Padma Purana refer to this place as Kadigai and since Vishwamitra got his Brahmarishi title here, it became Simhapuram
At the end of the Rama Avatar, Hanuman wanted to join Rama in his abode at Vaikuntam. However, Rama had other thoughts and asked Hanuman to go to Sholingur to protect the Sages from demons Kalan and Keyan. Hanuman could not initially kill the demons and he prayed to Lord Narasimha. Lord Narasimha appeared before Hanuman and gave him Shanka and Chakra with which Hanuman Killed the Demons also Lord Narasimha asked Hanuman to remain here, as Yoga Anjaneya, with the assurance that he would take Hanuman into Vaikunta Dham during Kali Yuga.
This is the only Divya Desam with such special prominence for Lord Hanuman.
