Karthigai Deepam is one of the oldest festivals in Tamil culture—so ancient that its roots go back to the Sangam period, nearly 2,000 years ago. Long before electricity, loud celebrations, or modern temples, people honoured the power of light and the mystery of nature through this sacred festival. That is why Karthigai Deepam is often called the oldest festival of lights in India.
This year we celebrate Karthigai Deepam on 3rd and 4th of December.
According to history and legends, the festival began with the story of Lord Shiva appearing as an endless pillar of fire. When Lord Brahma and Lord Vishnu argued about who was superior, Shiva revealed himself as an infinite flame, rising beyond the sky and sinking deep into the earth. Both gods tried to find the beginning and end of this fire—but failed. This story reminds us that divine energy is limitless and beyond human ego. To honour this event, people began lighting rows of lamps, symbolising the eternal flame.
The celebration became even more special in Thiruvannamalai, where the Arunachala Hill itself is considered as Lord Shiva in the form of fire. Every year, a massive Mahadeepam is lit on top of the hill, and its glow can be seen for miles away. Historically, kings, poets, and common people all gathered to witness this divine sight, turning the festival into a tradition that united entire communities.
At home, Karthigai Deepam carries a beautiful cultural meaning. Families place lamps in every corner to welcome prosperity and chase away negative energies. Old Tamil texts mention that lighting lamps during Karthigai brings courage, wisdom, and harmony to the household. Children eagerly help arrange the agal vilakku, while elders prepare timeless sweets like appam and pori urundai.
Karthigai Deepam is more than just lighting lamps—it is the glowing bridge between ancient legends, cultural heritage, and modern family joy. It reminds us that even today, a simple flame can carry centuries of history and brighten every heart with hope.
