Soorasamharam is the final day of Skanda Sashti dedicated to Lord Muruga. This is dedicated to the killing of the demon Soorapadman by Lord Muruga with his vel. In the year 2018, Soorasamharam is celebrated on November 13.
According to legend Soorapadman was a demon and had acquired tremendous powers and also had obtained the boon of immortality. However he started tormenting the Gods and this created havoc in the Universe. All the Gods approached Lord Shiva to help them. Then Lord Shiva created Lord Muruga with the flames emanating from his third eye. Muruga then received the Vel from Parvati. Then Muruga was ready to fight Soorapadman.
The demon fought for sometime and then sensing that his defeat was inevitable, he turned himself into a tree. Lord Muruga then split the tree into half with his Vel and the tree halves transformed into a cock and a peacock. Muruga made peacock as his vehicle and the image of the cock he embeded into his flag. This event is called Soorasamharam.
On the day of Soorasamharam, devotees gather in thousands in Muruga temples and offer puja to the Lord. This day is celebrated as the victory of the good over the evil.
Lord Muruga is very popular especially among the tamil community all over the world. Soorasamharam is observed in all the Muruga temples in South India, Malaysia and across the world.
