Talk about Karthigai Deepam and the picture that comes to mind is that of rows and rows of lamps or ‘vilakku’. On this day, every Hindu home lights the traditional Vilaku (diyas) in the evening. Locally, these lamps are known as ‘agal vilakkus.’
The day is also highly auspicious for Lord Muruga devotees as he was taken care by the six Krttika stars and the celebrations on Karthigai commemorate his divine birth. In popular Tamil belief, Karthikai Nakshatra is the birthday of Murukan.
Karthigai Deeepam is celebrated as Tirukarttikai in Tamil Nadu, Kerala, Sri Lanka, Malaysia, Singapore, South Africa and in other parts of the world which has Tamil population. People light lamps outside their home.
Especially in Tiruvannamalai, rows of lamps are lighted on the hill and this is most popular Karthigai Deepam.
The lighted lamp is an auspicious symbol and it is believed to usher in prosperity and joy.
