The Ratna Sabha Cosmic Dance & Oordhva Tandava Competition
According to sacred Purana legends, after slaying the demons Sumbha and Nisumbha, Goddess Kali took up residence in the dense Banyan forest (Vadaranyam). Her fierce, unbridled energy filled the forest with wild power, disturbing cosmic order. Sages prayed to Lord Shiva to calm Her wrath. Lord Shiva descended to Vadaranyam and challenged Goddess Kali to a cosmic dance competition (Tandava). As the divine dance reached its crescendo, Lord Shiva's earring (Kundalam) fell to the ground. Without pausing the rhythm of His dance, Lord Shiva lifted His left leg high above His head to His ear (Oordhva Tandava) and restored the earring with His toe. Out of feminine modesty, Goddess Kali conceded victory to Lord Shiva. Moved by Her devotion, Lord Shiva granted Kali a sanctum near the entrance, declaring that devotees must first seek Her blessings before entering the main sanctum. Lord Shiva manifested as Sri Oordhva Tandava Nataraja in the Ratna Sabha (Ruby Hall).
Saint Karaikal Ammaiyar's Head-Walking & Mukthi
The profound female Shaivite saint Karaikal Ammaiyar (Peyar) surrendered her physical beauty and assumed a skeletal form out of pure devotion to Shiva. On her pilgrimage to Thiruvalangadu, she considered the ground so holy that she walked upside down on her head so as not to pollute the sacred earth with her feet. Overjoyed by her unyielding devotion, Lord Shiva addressed her affectionately as "Amma!" (Mother!) and granted her eternal residence beneath His dancing right foot in the Ratna Sabha. Karaikal Ammaiyar composed her famous Thiruvalangattu Mootha Thirupathigam hymns here. A dedicated shrine for Karaikal Ammaiyar stands inside the temple prakaram.
Discovery of the Thiruvalangadu Copper Plates (1018 CE)
In 1903, the Archaeological Survey of India discovered 31 massive bronze ring-bound copper plates in a subterranean vault at Thiruvalangadu. Issued by Chola Emperor Rajendra I in 1018 CE, these famous Thiruvalangadu Copper Plates contain 816 lines of Sanskrit and Tamil epigraphy, documenting the genealogy of the Imperial Cholas, Rajendra I's naval conquest of Sri Lanka and Gangetic North India, and immense land grants (Devadana) to Thiruvalangadu Vadaranyeswarar Temple.
