Another legend associated with this temple is about King Sivathithan, who ruled Thiruvural and was troubled by the demon Thakkan. The king prayed to Lord Shiva of this temple, who instructed Goddess Kali to destroy the demon. Goddess Kali followed Lord Shiva's orders and killed Thakkan. For this reason, there is a separate shrine dedicated to Goddess Kali at the border of the temple, which attracts a large number of devotees. It is believed that Thakkan cried loudly before his demise, and this place came to be known as Thakkan Olam or Thakkolam, with “Olam” meaning "crying loudly."
Another reason for the name "Thakkolam" is the sacred tree of the temple, also called "Thakkolam" (Pottu).
An alternate version of the legend states that Thakkan, after conducting a grand yagna, invited all the celestial gods except Lord Shiva. To teach him a lesson, Lord Shiva instructed Veerabathrar to disrupt the yagna. Veerabathrar stopped the yagna and punished Thakkan by removing his head and replacing it with a goat’s head. Realizing his mistake, Thakkan prayed to Lord Shiva for pardon. Shiva advised him to go to the riverbank and invite Lords Vinayakar, Mahavishnu, and Brahma to witness his prayers. Upon Thakkan’s request, the three deities arrived. Since Thakkan's head had been replaced with a goat's head, his prayers sounded like the bleating of a goat. These prayers are known as "Chamakam," with each line ending with the syllable "may." Pleased with Thakkan’s prayers, Lord Shiva granted him salvation (moksha).
- Worshipped by Kamadenu :
Kamadenu, the divine cow, is also believed to have worshipped the lord at this temple by pouring milk on the lingam. Through this act, she was relieved from Theerkadar’s curse and regained her original form and divine powers. Upon learning of her restoration, Lord Indiran is believed to have come to Thiruvooral and took Kamadenu back to the celestial world.
- Worshipped by others :
It is believed that Sage Samvartha, along with Lords Mahavishnu, Indiran, Suryan, Chandran, Yama (the lord of death), the Saptha Kannikas (the seven divine virgins), the Pandavas, and Savitha Sivachariyar, have all worshipped the Lord of this temple to seek absolution for their sins.
