Swayambu Narasimhar Temple is located at Edarkundram, a peaceful village located near Thiruporur in the Chengalpattu district in Tamil Nadu. The temple is situated on a small hill surrounded by natural greenery, creating a calm and spiritual atmosphere away from city noise. Devotees have to climb around 50 to 70 steps to reach the temple, and the climb itself gives a feeling of devotion and peace.
This temple is believed to be more than 1000 to 1500 years old based on strong local traditions. Even though there are no clear inscriptions to confirm the exact period, it is considered an ancient Siddhar worship place. Devotees believe that the temple has existed for many centuries and has always been a place of deep spiritual energy.
The main deity is Lord Narasimha in a Swayambhu form, which means the Lord appeared on his own and was not sculpted by humans. The most special feature here is that the form of the Lord is naturally seen on the rock surface inside the sanctum. The Lord is seen under a five-headed Adisesha, which gives a rare and powerful appearance. In front of this natural form, there is also a Lakshmi Narasimha idol where the Lord appears in a calm posture with Goddess Lakshmi. Devotees come here to pray for protection, removal of fear, mental strength, and relief from life problems.
The temple has a very simple structure and is built directly on a natural hill. Unlike large temples with grand towers, this temple maintains a natural and ancient feel. The sanctum is part of the rock itself, preserving the Swayambhu form. Inside the temple, there are idols of Azhwars and Acharyas, and at the base of the hill, there is a small Hanuman shrine. The surroundings are quiet and filled with greenery, which adds to the peaceful spiritual experience.
There is no detailed written history available for this temple, but it is strongly connected with ancient Siddhar traditions. For many years, this temple remained a hidden spiritual place known mainly to local devotees. Over time, more people came to know about its significance. The temple has not undergone major changes and still retains its original natural form, which makes it more sacred and powerful.

The Sthalapurana of this temple is closely linked to the great Siddhar Idaikkadar, one of the 18 Siddhars of Tamil tradition. He chose this hill for deep meditation because of its strong natural energy and peaceful surroundings. It is believed that he performed intense penance here for many years, focusing his devotion on Lord Narasimha.
Pleased with his devotion, Lord Narasimha appeared before him and gave divine darshan. After blessing the Siddhar, the Lord did not disappear but chose to remain in that very place in a self-manifested form on the rock. This is why the temple is considered very powerful, as the deity is not man-made but a direct divine manifestation. The presence of the five-headed Adisesha above the Lord further symbolizes protection and divine power.
It is also believed that the fierce nature of Narasimha became calm here after blessing the Siddhar, and since then, the Lord is worshipped as a protector who removes fear and negative energies. The name Edarkundram is believed to have come from “Idaikkadar Kundram,” showing the connection between the Siddhar and this sacred hill.
Important festivals like Narasimha Jayanthi are celebrated with devotion as it marks the appearance of Lord Narasimha. Swathi Nakshatra days are considered very special for worship, and many devotees visit the temple on these days. Vaikunta Ekadasi is also observed with importance as a major Vaishnavite festival. Apart from these, Saturdays and special pooja days attract regular devotees who come seeking protection, peace, and strength.
