Besides the presiding deity Lord Swarnapureeswar in the sanctum sanctorum and  Mother Periyanayaki, there are shrines for Lord Vinayaka, Lord Muruga with Valli and Deivanai and the guardian deity Chelliamman.

Women pray to Mother Chelliamman seeking wedding boon while others pray for relief from Rahu-Ketu (serpent planets) adverse aspects of the planets.

As the temple is in a forest area, it is believed that a snake guards the temple.  Devotees believe that a snake is lying in front of the temple and it disappears when it hears the bell sound when the priest opens the doors.  Hence, those afflicted with Rahu-Ketu aspects, worship Mother and believe that they will be married with a suitable match soon.

Lord Muruga with six faces: The idols of Lord Muruga and His consorts Valli and Deivanai are the ones found from the ground.  These idols are installed in the sanctum sanctorum on the left hand side.  Pujas are regularly performed for Lord Muruga.  Lord Muruga has six faces.  As a Swayambu, He graces the devotees with boons of their wish.

Secular approach: With a view to ensure communal harmony among people of all religions, Chelliamman is taken in procession in Vailankanni and Nagai Bazaar.  People of all religions pray to Mother Chelliamman for profitable progress in trade, fishing, prevention of diseases and prosperity. The temple is praised in the hymns of Saivite Saint Tirunavukkarasar.

The traders in Nagapattinam desired to build a temple for Chelliamman in a place that was a forest area.  They made the idols ready.  While digging the foundation for the temple in Therku Poigainallur, they found the idols of Lord, Muruga, Valli, Deivanai and other sub-deity idols.  When they axed a tree near the present Ambica shrine, they found Goddess idol from the tree hole along with other idols also.  They installed their own-made idols within the temple and other ones outside the temple.  They named the Lord Swarnapureeswarar and Mother Periyanaki.  Goddess Chelliamman graces as the guardian deity.
