As an annual festival feature, when the moon shows its whole disc illuminated in the month of Karthigai the celebration becomes a week long temple function. A big brass vessel especially designed in the form of a lamp is lifted to the peak of the hill; it is filled with tins and tins of ghee and pots and pots of butter; and an enormously thick wick made of loosely twisted woven fibers (clothes) is immersed into the vessel and one end of the wick is drawn out to the apex and is ignited with burning camphor and the thick wick fully soaked in ghee acting by capillary attraction conveys the ghee the main illuminant to the flame around 6 pm when the sunlit full moon disc emerges from the east and comes on to the horizon. The luminous glow of the lamp atop the hill opens the eyes of millions of people to something divine and auspicious and ardent devotees and others see in the burning light lord of the world and remain visibly, moved with their mouths uttering "Om Arunachaleshwaraya Namaha", Here man lights the largest wick of the largest lamp once a year and the world goes into rapture sings his songs of grace.
