Vinayaka of the temple is worshipped as Siddhi Vinayaka.  The Amrutha Theertham-sacred spring is outside opposite the temple.  On the bank of theertha is Sri Vinayaka in the name of Aadhi Gajanathar.  The structure is such that the Vimana of Aadhi Gajanathar is visible from the Lord’s shrine within the temple.  On the Masi Magam day, five deities-Panchamurthys, Lord Koneswarar, Mother Perianayaki, Lord Vinayaka, Lord Muruga and Lord Chandikeswara visit the Amrutha Theertha for Theerthavari festival.

Lord Shiva, as a swayambumurthy is facing west from a square stage-Chatura peeta.  The scar caused by the sharp nose of Garuda the eagle is visible on the Linga.  Mother Perianayaki with all the attributes of Mother Durga graces the devotees from a separate shrine facing south.  She is worshipped as Bruhath (big) Durgambika.  There is no Durga in the Shiva goshta wall.  The temple was renovated by Kochengat Chola.  Saint Tirugnana Sambandar had mentioned this temple in his hymn as Ezhilkola Mada koil – beautiful mada temple.  As Lord Shiva granted his darshan from a high level place, it is praised as mini Kailash. 

Koneswarar, Soodha Maharshi, Sage Brughu and Thalappiar had worshipped Shiva here.  The Lord is named Koneswarar as He loves (Ko) beings – Easwara-Lord.  As the mouth piece of Nectar pot (kudam) fell here, the place is called Kudavasal.  Lord is known also as Amudha Lingeswarar and Vanmeekanathar as He was in an Ant-hill-Vanmeekam.  Lord Kasi Viswanatha graces opposite the entrance.  The rays of Sun fall on the Lord for three days during March-April.
