Karthigai Deepam: The Festival of Lights Rooted in Divine Radiance

Karthigai Deepam is an ancient Tamil festival of lights, celebrated with spiritual fervor and glowing lamps. Observed during the Tamil month of Karthigai (November–December), it is often considered the South Indian counterpart to Diwali, but with its own distinct traditions and mythological significance.

The festival is deeply connected to Lord Shiva, particularly in his form as an infinite pillar of light (Jyotirlinga). In the temple town of Thiruvannamalai, a grand beacon is lit atop the Annamalai Hills, symbolizing Shiva's boundless energy and divine presence. This sacred flame, known as Mahadeepam, draws thousands of devotees each year.

In homes, people light rows of agals (clay oil lamps) at dusk, decorate thresholds with kolams, and offer traditional sweets like appam and pori. It’s a festival that blends devotion, community bonding, and the symbolic triumph of light over darkness.
