Soorasamharam = Asura + Samharam

According to Kanda Puranam, once three asuras Soorapadman, Singamugasuran and Tharakasuran were causing great troubles to the celestial Devas. To destroy them, Lord Shanmuga took avatar from the third eye of Lord Shiva. Lord Muruga accepted the vel ayutham (spear weapon) from Goddess Parvati and proceeded along with Virapagu Devar and other devas to fight Soorapadman and his demon army.

During the war, Lord Muruga transformed Singhamugasuram as vahana of Goddess Shakti. Soorapadman after fighting tried to escape by hiding himself as a mango tree in the seabed. Lord Muruga split the mango tree and converted one half as peacock vahana and other half as 'ceval' or rooster banner.

After providing great blessing to the asuras, Lord Muruga relieved the Devas. The destruction of three Asuras symbolises the destruction of anavam (ego), kanmam and maya (illusion).

Devotees thronged the temple. The events leading to destruction of three asuras by Lord Muruga is enacted. After the destruction of Soorapadman, abhishekam is held for the mirror image of Lord Subramaniya Swamy and he is decked up and ready for the procession, with Valli and Deivanai.
