Thaipusam Day

Thai Poosam Kavady) is a Hindu festival celebrated mostly by the Tamil community on the full moon in the Tamil month of Thai (Jan/Feb). Pusam refers to a star that is at its highest point during the festival. The festival commemorates both the birthday of Lord Murugan (also Subramaniam), the youngest son of Shiva and Parvati, and the occasion when Parvati gave Murugan a vel (lance) so he could vanquish the evil demon Soorapadman.The origin of Lord Skanda, the purpose of His avatara and its significance are of much importance to all seekers after Truth. During the battle between the Asuras and the Devas, the latter were defeated several times by the former. The Devas were unable to resist the onslaught of the Asuric forces. In despair, they approached Lord Siva and entreated to give them an able leader under whose heroic leadership they might obtain victory over the Asuras.
They surrendered themselves completely and prayed to Lord Siva sincerely. The gracious Lord granted their request by creating mighty divine warrior, Lord Skanda, out of his own power or Achintya Sakti. This great son of Lord Siva at once assumed leadership of the celestial forces, originated them, inspired them and attacked the asuric forces. The asuras were routed and a glorious victory was gained by the Devas.

Generally people take a vow to offer a kavadi to the Lord for purpose of tiding over or averting a great calamity. For instance, if the devotee's son is laid up with a fatal disease, he would pray to Shanmuga to grant the boy a lease of life in return for which the devotee would take a vow to dedicate a kavadi to Him. Though this might on the face of it appear mercenary, a moment's reflection will reveal that it contains in it the seed of love for God. The worldly object is achieved: and the devotee offers the kavadi. After the ceremony is over, he gets so much intoxicated with love of God that his inner spiritual chamber is opened. This too ultimately leads to Para Bhakti -Supreme devotion.
