Thirumeeyachur temple is located in Thiruvarur – Mayiladudhurai road near Nannilam.
Dreaded demon Pandasura was harassing sages and Devas. They surrendered at the feet of Mother Parasakthi for protection. Responding to their appeal, Devi rose from a Yaga Gunda, mounted on the Sri Chakra Rath with the name Lalithambika, waged the war against the demon and destroyed him. She was very furious then. Lord Shiva asked Mother to go to Earth, assume the name Manonmani and perform penance and shed her fury. Mother came to this place and became soft and merciful. She created Vak Devathas-deities ruling words- and asked them to sing Her praise with 1000 names. This became the holy Lalitha Sahasraname beginning with the words, Sri Mathre meaning “Mother of prosperity”.
