According to the legend, once Sri Karumaari Amman took form of a fortune teller and went to Sun God for predicting his future. Sri Surya Bhagawan neglected Her and Sri Ambaal vanished from his sight, because of which Sun God lost his powers and glory. Then Surya Bhagawan realized that it was none other than the Goddess Herself and came and worshipped her here at Thiruverkaadu, seeking apologies. Goddess pardoned him with mercy and Sri Surya Bhagawan requested her to bless that Sunday (Sun God’s day) be the auspicious day for the Devi here. Goddess obliged to it.

The Goddess asked Sage Agasthiyar to look for a holy place where she can perform the heavenly duties assigned by Lord Shiva. When Sage Agasthiyar was thinking of such place, he heard an Asareeri (அசரீரி – a holy voice) saying that the place where he was standing itself is a holy place. Goddess took abode here as Sri Karumaari Amman and also blessed the place that one will be removed of all the sins by worshipping Her at Thiruverkaadu.

According to legend, Goddess Kamakshi was performing thapas on Panchagni (fire) in Maangaadu praying Lord Shiva to marry Her. Her penance was so intense that the whole surroundings became too hot and all living beings suffered because of enormous heat. But Lord Shiva was meditating deeply with His eyes closed. Sages and Devas worshipped Lord Vishnu to save the world from the heat of the penance. Lord Vishnu directed Sri Mahalakshmi to save the world.
Goddess Sri Mahalakshmi came down here to this place in the form of a cow and worshipped Lord Shiva to make Him open the eyes, so that the world is saved. Pleased with Her prayers, Lord Shiva opened His eyes, after which the heat of the place subsided and became cooler.
As Sri Mahalakshmi worshipped here in the form of a cow, the place came to be known as Kopuri (In Thamizh, Ko means cow) and later corrupted to become Kovur. At later stages Kulothunga Chozha had built this temple beautifully.

The Kovur Pancharatnams are "Ee Vasudha" (Sahaana Raagam),
