The Ambal is swayambu and appear with twin arms and donned with serpent crown.  There is a small vimanam constructed above her, in which are the female doorkeepers.  During the abishekam  performed from morning 6.00 to 11.30 we can worship the swayambu form of the Amman.  A fee of Rs.150/- is collected from the devotees to participate in the abishekam function.

Those who pray to her offer turmeric, sandal, saffron powder, kaappu and also annabishekam.  Generally, only in the Siva temples, the Lord is worshipped performing annabishekam.  Since the Ambal here is an aspect of Parvati Devi, she is worshipped by performing annaabishekam.  To prepare the Pongal offering to her, the temple uses only the dried cowdung.  The residue ashes are distributed as prasaadam.

The traditional belief is that Mundaka Kanniamman holds the power of the Trinity – Siva, Vishnu and Brahma.  The Banyan tree is behind Ambal’s sanctum.  Within the tree is the snake-cove and beside the tree is the sanctum of Naaga Devathai. Those with serpent-curse, worship the Naaga Devathai by offering milk, rose-water, turmeric abishekam and by lighting ghee-lamp.  On the left of the Prime sanctum, the procession Ambal graces us seated on the throne, flanked in both sides with Simha Vahanam – lion carriers.  In the prakaaram are the sapta kannikas appearing in the linga form. Jamadagni Maharishi and his son Parasuramar are seen as security gods on both their sides.  In front of the temple is Lord Vinayaka under the pipal tree.  Those with serpent-curse install Nagar (serpent) images under this tree.  This is the holy place where Vaayilaar, one of the Nayanmar and Peyaalvaar, one of the aalvaars were born.  Around this temple are the famous  Kapaleeswarar temple,  Parthasarathy and Madhavap Perumal temples.  By having the darshan of Mundaka Kanniamman, we can also go to these temples.

In the olden days there was a lotus pond in this place. Under the Banyan tree in the banks of this pond, Ambal manifested herself in swayambu form.  In the beginning, the devotees erected a small hut as sanctum for Ambal and worshipped her.  Later, an elaborate temple was structured.  Since there has been no sanction from Ambal, the Prime sanctum continues to be the hut.  It is said that Ambal in order to indicate simplicity lives in the hut and graces us.

Ambal’s swayambu form of this holy place looks like a lotus bud. Hence, she is called ‘Mundaka Kanniamman”.  ‘Mundakam’ means ‘lotus’. The significant feature is of the trident, the primary weapon of Devi, seen at the center of the swayambu form.
