Worayur near Trichy also has other names as Vasapuri, Kozhiyur and Mukkeeswaram.  The place was developed by Sooravaditya Chola.

People use to submit their problems in writing and tie it in the trident.  They believe that Amman will go through their petitions and redress their grievances.  They light lamps in Her shrine for removal of obstacles in marriage talks and also solve the adverse aspects on their children.

Of the many incarnations of Shakti, Kali avtar is very significant.   Mother Vekkali Amman graces majestically sitting on a Yoga Peeta facing north.  She is holding trident, Udukkai, the rope-pasam and Akshaya Patra (a vessel from which food would be constantly flowing to feed all beings) in Her four hands.  Bangles, Mangalsutra, pearl chain, necklace, crown on the head are shining on Her form.  Her left leg is on the demon and the right bent.  There is no roof tower as the Shakti is on a plain ground.  Generally in Shakti temples, the deity is seen with her right leg on the demon and left leg bent, while it is vice-versa in this temple, a rare form.

Paranthaka Chola was ruling the region then.  His Guru Sarama Munivar was a staunch Shiva devotee.  He created a garden for Thayumanaswamigal in TrichymFort growing flowers for puja to the Lord.  The garden has lot of flowers of various varieties. 

But the king was taking those flowers for his wife.  His men took the flowers.  Sarama Muniver told the king that he was doing wrong but the king not only humiliated the Acharya and proudly said that only flowers remaining there would be allowed for his puja.  The Guru appealed to Lord Shiva.  Infuriated Lord Thayumanava turned west and opened His forehead eye.  Worayur was reduced to ashes with the fire rain from the Lord’s forehead.  King’s fort was destroyed.  People began to run for safety.  The only place that was not affected by the Lord’s fire was the open ground where Vekkali Amman stayed.  People surrendered to her.

Responding to the prayers of the people to get back their homes, Mother Vekkali took the form of a full moon and appeared before the Lord to quench His fury.  Lord calmed.  The fire rain stopped.

Queen Bhuvanamadevi was also caught in the fire rain.  She was pregnant then and it was in an advanced stage.  Unable to bear the fury of the flames she jumped into the Cauvery and was drawn by its current.  A Brahmin saved her at Utamacherry and took care of her.  She delivered Karikal Peruvalathan in his house.  She was a staunch devotee of Vekkali Amman whose mercy protected her and the Chola dynasty survived.  Worayur people are very grateful to Vekkali Amman and continue to worship her as their protector Goddess for generations.
