Brahmmotsavam is celebrated for Mother-Goddess on Aadi Pooram day in July-August.

Those suffering from Leprosy pray to the Lord in the temple.

While offering the Deepa Aaradhana to the deity, a mantra is chanted – beginning as "Om Rajadhi Rajaya Prasahya Sakine" (Sanskrit) in which the word ‘Kameswwara" occurs in the middle of the chanting. Those desirous of the darshan of this deity Kameeswara should go to Kokilambika-Kameeswarar temple in Villianur near Puducherry. This Nama (name) is pronounced in all the temples.

The significance of the temple relates to the history of a Chola King Dharmabala Chozhan ruling Kamalapuri then who suffered from leprosy due to his Karma in his previous birth. He worshipped Lord Shiva in this temple and got cured.

He created a town here which was earlier a forest of Vilwa trees and also constructed a temple and named the place Vilwanallur which in course of time changed as Villianur. The temple has a mention in Thevaram hymns.

Prasava Nandhi: The other significance of the temple is the Prasava Nandhi. Prasava means delivering a child. Though Nandhi (the bull vehicle of Lord Shiva) usually installed facing the deity, there is also a small Nandhi before this Big Nandhi.

Kala Bhairava in the temple graces here without His Dog vehicle and therefore, the place is venerated as a place of salvation.

Rays of Sun fall on the presiding deity on 9, 11 and 19 in the month of Panguni (March-April) offering his worship to the Lord.

Lord Brahmma, Lord Narasimmah, Indira, Sun, Adisesha (the divine snake), Cupid (manmatha), Moon, King Dharmabalan, Sakalanga Soundari, Govindan and others had worshipped in this temple. Lord Shiva graced his darshan to Lord Vishnu here on a Poornima day falling on a Sunday. Following this event, devotees throng the temple on Poornima days (Full Moon day) falling on Sundays hoping that the darshan would bring them the boon they seek.

Once, Lord Vishnu and Brahmma wanted to establish their supremacy over the other and asked Shiva to decide the issue. Lord Shiva said that the one who would find His feet and crown would be the winner. Brahmma played a trick and had to incur a curse. When Brahmma prayed to Lord Shiva for the relief, he was advised to grow Vilwa trees on the banks of River Mutharu in the Thondaimandalam region and worship Lord Shiva for the release. Brhamma followed the advice of Lord Shiva and got him released from the curse
