Special features, deities and other shrines:

Since Lord Brahma was destroyed and created later and given dnyana updesh by Lord Shiva, the place is known as Brahmapuri, Thirumeidnyanam and Kadaiyur Mayanam. Lord Shiva is known as Brahmapureeswarar. In the koshta we have the koshta murtis - Lord Dakshinamurti, Ardhanareeswarar, Lord Vishnu, Vishnu Durga, Bhairav, Chandikeshwar, Nardana Vinayaka. Lord Dakshinamurti in the koshta is along with six of his disciples but he is not seating under kallal tree (Indian rock fig, Kallalashwattha, Audumbar in Marathi) though he usually sits under it.  There is a separate shrine of Lord Muruga. He is with his consorts Valli and Devasena and he is called as Singaravelar. The idol of Singaravelar is unique. He is depicted with a bow and a spear in his hands in a warrior posture ready for going to the war. He wears a rudraksha mala and wears slippers known as kurradu in Tamil. He is slightly slanting towards the left. The idol resembles that of Lord Sriram. Singaravelar is considered as a manifestation of Lord Vishnu who is his maternal uncle. Similar to Chandikeshwar in Lord Shiva’s temple there is a Chandikeshwar in Lord Muruga’s shrine also. He is known as Guhachandikeshwar. Lord Vinayaka is here known as Pranava Vinayaka and he is depicted with a flat stomach. It is believed that he also heard the updesh given to Lord Brahma by Lord Shiva with folded hands and full concentration. Hence he has a flat stomach. In the corridors we have the idols of Nataraja, Kalyana Sundarar, the four shaiva saints known as Nalavar, Lord Mahavishnu (known as Sri Pillai Perumal), Gajalakshmi, Chandeshwari, Sri Bhikshatanar and Bhairav. One of the 18 great sidhhars Sri Pambatti Siddhar lived here. 

Sthala Purana:

According to Purana, at the end of each yuga Lord Shiva is believed to create a great deluge (pralay) to destroy the universe. In the process, Lord Brahma also gets destroyed. When the new yuga starts, Lord Brahma is recreated by Lord Shiva. During one such yuga Lord Brahma was destroyed and brought back to life at this place. Lord Shiva gave Shiva dnyana updesh (Brahmadnyana updesh) so that Lord Brahma could start the creation. Hence Lord Shiva is known as Brahmapureeswarar at this place. This is the third such place where Lord Brahma was given Shiva-dnyanopadesh. 

According to kshetra purana Lord Shiva created a well (pond) with water from Ganges for Sage Markandeya to continue his worship of Lord Shiva at this place. This well is located very near the sacred tank of the temple. Even now water is taken from this well to Thirukadaiyur temple (Amirthakadeswarar Temple) daily for abhishek of Lord Shiva. The water from this well is used only for the Amirthakadeswarar. According to another kshetra purana, Chalukya king Emakeridan who was defeated in a battle and lost his kingdom came to this place to worship Lord Shiva after worshiping at nearby Shiva temples. He prayed to the lord for getting his kingdom back. When he came and prayed at the shrine of Singaravelar, Lord Muruga took the form of a king. He went with the king's army and defeated the enemy and got the kingdom back for King Emakeridan. That's why the idol of Lord Muruga (Singaravelar) is in warrior form. The king donated about 53 acres of land to the temple of Singaravelar which is still known as Singaraveli.
