Story behind the festival

A long, long time ago- the world was torn apart by an infernal war between the Devas (celestial beings) and the Asuras (evil forces). Tired of constant attacks from the Asuras, the Devas paid homage to Lord Shiva and asked for his protection. Moved by their plight, Lord Shiva agreed to help the hapless Devas.
Lord Shiva opened the central eye on his forehead, radiating six sparks of fire. At the convergence of these sparks and through a series of celestial transformation, Lord Murugan appeared. He brought forward this powerful divine personality with elements of Himself and yet distinct from Him, powerful and brave enough to defeat the tyrannous Soorapadme - the meanest and most powerful of the Asuras. Armed with a Nyanya Vel (golden spear) presented to him by Lord Shiva, Lord Murugan went into battle with the evil force. A fierce battle ensued. Finally with one fatal stroke, Lord Murugan slayed Soorapadme. The divine converted one portion of the slain enemy into a peacock as his vehicle and the other portion into a cock adorning his banner.
Lord Murugan, the son of Lord Shiva is considered the very manifestation of valour, beauty, youthfulness, vitality, masculinity, valour and the abode of happiness. Thaipusam celebrates the very essence of Lord Murugan and the power of good over evil.
