Connection between Mathurakaaliyamman temple of Siruvachur and Kannagi is also establised.
Kannagi after her vengence against Madurai, visited many places for 'Shanthi'. She once came to Srivachur, the temple then was 'Selliyamman temple'.
There was a 'poosari' in selliyamman temple, who had obtained a promise from the goddess that she should do as he wishes. Mother compasionate, gave her consent. The 'Poosari' started performing atrocities, and Selliyamman could not bear it, but she could not do anything because of the promise.
During this time, when the 'Poosari' was away on his duties, Kannagi visited the temple, and she found Goddess Selliyamman, very muich unhappy. She then was told by Goddess what happened. Kannagi, with the permission of Seliyamman, requested 'Madhuraiyaritha Kaali', to help her. Kaali, then requested Selliyamman, to go to a nearest hill and stay up there, and she will occupy her position here in the temple.
The 'Poosari' who retuned to temple after his job, was surprised and shocked to find Kaali, with all her fury sitting in place of Selliyamman. Knowing his end, he requested his samadhi to be in the temple, and people to stamp over his body and worship her, and Kaali to stay parmanently at this temple. Kaali granted his wishes.
Below the steps of moolasthaanam, si belived to be that 'Poosari's' samadhi.
So Siruvachur became famous for Madhurakaali and still Selliyamman occupies a temple in nearby hill.
