Origin/History :-
The temple dates back to the Medieval Chola period and is one of six temples considered equivalent to the temple in Varanasi. The other five temples in this group are Thiruvenkadu, Mayiladuthurai, Tiruvaiyaru, Tiruvidaimarudur, and Tiruvanchiam.
This temple is also a Maadakovil, constructed by Kochengat Chozhan. The name "Chayavanam" or "Chaikadu" comes from the Tamil word "Chai," which means "Korai" (a type of grass), reflecting the fact that the area was once covered with this grass.
Puranic Significance :-
- Lord Vishnu Worshipped Shiva Here: Lord Vishnu once worshipped Shiva at this temple to obtain the famed conch, Panchajanyam. In the same village, there is a notable temple called Thalai Sanga Nanmathiyam, a Divyadesam dedicated to Lord Vishnu.
- Lord Shiva’s Thiruvilayadal with Iyarpagayar: In a divine play, Lord Shiva appeared as a devotee and requested Iyarpagayar to send his wife with him. The devotee and his wife compiled without hesitation. Shiva warned that enemies might attack on the way and asked Iyarpagayar to escort him to the border for safety. Iyarpagayar agreed and defended the Lord from any opposition. Upon reaching the border, Shiva revealed his true form with Parvathi and instructed Iyarpagayar to return home with his wife and live happily. This miraculous event is said to have taken place in Chayavanam.
- Indra’s Attempt to Relocate the Temple: Indra's mother, Athithi, wished to worship Chayavaneswarar on earth. Upon finding her, Indra tried to transport the temple to Indraloka using his white elephant, Iravadham. However, Mother Parvathi, known as Kuyilinum Inia Mozhiyal for her sweet voice, intervened. She, along with Lord Shiva, advised Indra to continue the worship on earth and be blessed, rather than relocating the temple.
- Murugan with Bow & Arrow and Veeragandamani: At this temple, Lord Muruga is depicted with a bow and arrow, ready for battle against Soorapadman, instead of his usual weapon, the Vel. The idol of Muruga was reportedly discovered in the sea and brought to the temple. He is also adorned with the Veeragandamani (anklet) on his right leg, gifted by Lord Shiva. Devotees who fear enemies come to this temple to seek protection and courage, as worshipping Muruga here is believed to empower them to overcome fears and advance in life.
