Dancing in a hypnotic trance to the rhythm of drums, devotees of Muruga carry the 'Kavadi' a flower decked decoration, all the way up the Palani Hills to fulfil their vow. According to Hindu mythology, Idumban is said to have carried two sacred hillocks on two ends of a pole laced on his shoulders.
The ancient Tamils when they went on pilgrimage,

carried the offerings to the gods tied on the either end of the long stick, which was balanced on the shoulders. In order to lessen the boredom of the long travel they used to sing and dance about the gods. Kavadi Aattam has its origin in this practice. Special songs were created to be sung while carrying the Kavadi Sindhu. This dance is performed only by men. It is done by balancing a pole with pots fixed on either end, filled with milk or coconut water. The poles are made from Purasai or Teak wood. On top, bamboo strips are bent like a half-moon, covered with saffron cloth and further decorated on the sides with peacock feathers. This is mainly a religious dance, performed in worship of Lord Murugan, the second son of Siva. The dance is accompanied by Pambai and Naiyandi Melam.

The Most Important Custom
The most potent propitiatory rite that a devotee of Lord Muruga undertakes to perform is what is known as the "Kavadi". The benefits that the devotee gains from offering a Kavadi to the Lord are a million fold greater than the little pain that he inflicts upon himself.
Generally, people take a vow to offer the Lord a Kavadi for the sake of tiding over a great calamity. Though this might on the face of it appear mercenary, a moment's reflection will reveal that it contains in it the seed for the supreme love for God. The worldly object is achieved, no doubt, and the devotee takes the Kavadi; but after the ceremony he gets so God-intoxicated that his inner spiritual chamber is opened. This is also a method that ultimately leads to the supreme state of devotion.

Agni Kavadi
This is the most difficult Kavadi-offering. With the Kavadi hanging on his shoulders, the devotee walks through a pit of burning coals. The devotees all around the pit sing hymns in praise of the Lord. The beating of the drums and the burning of the incense make the entire atmosphere awe-inspiring. The real devotee gets into a state of ecstasy and easily walks over the fire.

Celebrations
The Kavadi festival is celebrated at all shrines of Lord Muruga. Dancing in a hypnotic trance to the rhythm of drums, devotees of Muruga carry the Kavadi all the way up the Palani hills to fulfill their vow. Ettukudi Kavadi Festival is a famous festival celebrated during the months of April-May. Devotees from places and villages around this temple come here with Kavadis, milk pots, coconuts, cocks and goats. This is a major crowd pulling festival where one can see the true Tamil culture in its habitat.

Celebration At Palani
At Palani Thaipusam is a ten-day festival held in the Periyanayaki temple. Since the festival falls in January - the post harvest season, the exuberance of the agriculturists and their lusty participation lends unique splendour to the temple. The most remarkable feature of this festival is the parading devout 'Bhaktas' (devotees) bearing Kavadis. The yellow robed 'Bhaktas' coming from several distant places dance their way through the streets to reach the Muruga Sannidhi to the accompaniment of music, both instrumental and vocal. Many strangely and ghastly traditions, like the lips pierced with mini silver lance, and locking of the mouth with metal ring to maintain perfect silence and drawing of small make shift chariot with its chain hooked into the back of devotees strike the eye of spectator during the festival.
