Thiru Kodimaada Chenkundrur(Tamil: திருக்கொடிமாடச்செங்குன்றூர்) (now referred Tiruchengode) is an ancient Hindu Temple known for its unique manifestation of Half Male Half Female Lord Arthanaareewarar (Shiva). The temple is situated on a Hill which is 2000 ft above mean sea level which could be reached either by road or climbing up 1206 steps. It is located in the town of Tiruchengode in the Indian state of Tamil Nadu which is 350 km southwest of Chennai and 120 km northeast of Coimbatore.
Once Lord Vishnu, Lord Brahma, Indra and sage Birungi went to Kailash to worship Lord Shiva. They were directed towards Lord Shiva by his Vahana, Nandhi. Everyone first had a darshan of Lord Parvathi and then proceeded to Lord Shiva. But, Sage Birungi directly marched to Lord Shiva. Parvathi Devi, annoyed by his act, sucked the flesh from the Sage's body to stop him proceeding, but the sage forwarded. Lord Shiva recognized this drama of Parvathi and blessed Birungi with a third leg. After the departure of the Sage, Lord Parvathi appeased Lord Shiva about her penance. After Lord Shiva's approval, Parvathi Devi along with her crew went to a hilltop and performed the same. As a result of this penance, she demanded a will for getting a portion for her in Lord Shiva's sacred body thus granting the devotees for a integrated worship, which was granted by Lord Shiva. This led to the manifestation of half men and half women depiction Arthanaareswarar. Thus Lord Parvathi took up the left side and rest right by Lord Shiva. This signifies the creation of this manifestation.
It is also believed that long ago there held a battle between Adiseshan and Vayu to prove their mighty powers. This resulted in devastating disasters and the then sages gave an idea to them. Accordingly, Adiseshan has to cling to Mount Meru with his hood and Vayu has to release him by his valour. But the former succeeded. Vayu, out of anger, stopped the air as a result all living beings fainted. Sages convinced Vayu to release his hold. By the sudden release of air by Vayu lead the top of the mountain with the head of Adisesha, thrown into earth on three places with flesh and blood and making it red and thus the name Chengodu. There is a 60 ft long snake carved on the hill, and hence the name as Nagamalai.
