A king ruling this region then, prayed to Lord Shiva for child boon and performed a yajna. Through His voice, Lord assured the king that Ambica would be his daughter. When the king set out on hunting, he found four female children, brought up them as his own daughters. They were Shiva devotees by their very nature. When they attained age, king begged Lord to marry them. Lord was happy to grant king’s wish. They are the Ambicas in four places – Sarivar Kuzhali in this temple, Vaaitha Tirukuzshal Nayaki in Tiruchengattangudi, Karundhar Kuzhali in Tirupugalur and Vandar Kuzhali in Tirumarugal.
They also bear the common name Shoolikambal as they helped a poor pregnant woman deliver her child during absence of her mother who was stuck at the other bank of the river due to heavy floods. Shool or Karu in Tamil means pregnancy.
Karu Katha Ambica is other name of the Mother in the temple.
As Ambicas returned late, they could not enter the temple. Mother shrines are outside temples in these four places. During the Arthajama pujas (final night pujas) samba rice with pepper, seeragam, salt and ghee is offered as nivedhana, a diet prescribed for mothers after delivery.
