Karthigai Deepam is one of the oldest and most visually magnificent festivals of South India, celebrated on the full moon day (Purnima) of the Tamil month of Karthigai (November–December). While Diwali is the pan-Indian festival of lights, Karthigai Deepam holds that distinction uniquely for Tamil Nadu, with a tradition of lighting rows of oil lamps (deepa bharani) in homes, streets, and temples creating an ocean of golden light across the state.
The centrepiece of Karthigai Deepam is the Maha Deepam — a massive beacon lit atop the sacred Arunachala hill in Tiruvannamalai. According to Shaiva theology, Lord Shiva manifested as a column of infinite light (Jyotirlinga) to resolve a dispute between Brahma and Vishnu about who was supreme. Neither could find the top or bottom of this blazing column of light. Arunachala hill is revered as the earthly form of this column of fire, and the Maha Deepam — a cauldron of ghee ignited at the summit — symbolises that primordial divine flame. The beacon is visible for miles around and draws over a million pilgrims to Tiruvannamalai annually.
The festival also honours the birth of Lord Murugan, who according to tradition was born from six sparks of fire that flew from Shiva's third eye during the cosmic battle, each spark becoming one of his six faces. The Karthigai nakshatra (Pleiades star cluster) under which the festival falls is considered Murugan's birth star. In 2026, Karthigai Deepam falls on 30 November, and the great flame atop Arunachala will once again signal Shiva's presence to millions of devotees across Tamil Nadu.
Significance of Karthigai Deepam
Why Karthigai Deepam is Spiritually Profound:
Karthigai Deepam carries multiple layers of spiritual meaning that make it one of the richest Hindu festivals:
- Shiva as Jyotirlinga: The festival re-enacts the most fundamental myth of Shaiva theology — Shiva's self-manifestation as infinite light to demonstrate that he transcends both the creative principle (Brahma) and the sustaining principle (Vishnu). The Maha Deepam at Arunachala is this cosmic truth made visible.
- Arunachala as Sacred Geography: The Arunachala hill is not merely a location for a temple but is itself considered Lord Shiva. Walking around the hill (Girivalam) on Karthigai Purnima is one of the most meritorious spiritual acts in Tamil Shaivism, believed to equal the merit of bathing in all sacred rivers.
- Light as the Self: In Advaita Vedanta, Arunachala is particularly sacred because Sri Ramana Maharshi taught that the hill represents the Self (Atman) — the inner light of pure awareness. Karthigai Deepam is therefore also a celebration of self-inquiry and the light of consciousness.
- Birth of Murugan: The Karthigai nakshatra is Murugan's birth star, making this festival doubly auspicious for Murugan devotees. The six lamps traditionally lit in Tamil homes on this day represent the six faces of Murugan.
- Ancestral Veneration: Lamps lit on Karthigai Deepam are believed to guide and comfort the souls of departed ancestors, making the festival a link between the living and the dead.
- Tamil Cultural Identity: Karthigai Deepam is among the oldest documented festivals in Tamil literature, mentioned in Sangam-era texts over 2,000 years old, making it a living connection to ancient Tamil civilization.

Lord Shiva is the primary deity of Karthigai Deepam. He is worshipped in his form as Annamalai (the immovable hill) or Arunachaleswarar at Tiruvannamalai. The Maha Deepam represents his Jyotirlinga — the column of fire and light that is his primordial cosmic form. The deepa (lamp) lit before Shiva on this day is considered a direct offering to his essential nature as divine light.
Lord Murugan (Kartikeya/Skanda) is the second major deity of Karthigai Deepam. The Karthigai star (Pleiades/Krittika) is his birth nakshatra. He was nurtured by the six Krittika maidens, which is why he is called Kartikeya. Six lamps are lit in his honour in Tamil homes, representing his six faces. Major Murugan temples like Tiruchendur and Palani hold special celebrations on this day.
Goddess Parvati is also honoured as she is inseparable from Shiva at Arunachaleswarar Temple, where she is present as Unnamalai Amman. She is believed to have done penance at Arunachala to merge with Shiva's form as light.
Brahma and Vishnu appear in the mythology of the day as the two deities who searched for the limits of Shiva's infinite light column and acknowledged his supremacy.
How to celebrate Karthigai Deepam 2026
How to Observe Karthigai Deepam at Home — Step-by-Step:
1. Cleanse the Home: In the morning, clean the entire house thoroughly. Draw kolam (rangoli) at the entrance using rice flour. Traditional Karthigai kolam patterns feature lamps and dots.
2. Prepare the Lamps: Gather clay oil lamps (kuthu vilakku and smaller agal vilakku). Clean and fill them with sesame oil or ghee. Cotton wicks are preferred. Traditionally, an odd number of lamps is lit indoors and rows of lamps are placed along walls, steps, and terraces.
3. Puja Setup: Set up Shiva and Murugan idols or images. Place six lamps in a row before Murugan's image specifically to honour his Karthigai birth. Light incense and offer fresh flowers — preferably white flowers for Shiva and red/yellow for Murugan.
4. Lighting the Deepam: At dusk (sandhya kalam), light all the lamps simultaneously. Begin with the main lamp before the deity, then light all household lamps. The act of lighting should be done with a prayer: "May this light remove all darkness from our lives."
5. Recite Hymns: Recite Thiruvembavai (for Shiva), Thirupugal (for Murugan), or the Arunachala Aksharamanamalai composed by Ramana Maharshi. The Shiva Panchakshara mantra "Om Namah Shivaya" should be chanted 108 times before the main lamp.
6. Deepa Bharani at Temple: If possible, visit the local Shiva temple in the evening for deepa bharani — the ceremonial lighting of hundreds of lamps in rows around the temple. Many temples also have special abishekam on this day.
7. Arunachala Girivalam (for those in Tiruvannamalai): Walk the 14 km circumambulation path around Arunachala hill barefoot on Karthigai Purnima. This is considered the most meritorious act on this day. Begin the walk when the Maha Deepam is lit atop the hill.
8. Fasting and Prasad: Many devotees observe partial fasting on this day, eating only after the evening puja. Prepare sweet pongal, payasam, or nei appam (ghee-fried rice cakes) as naivedyam (food offering) for the deities.

- Murugan Temples (Palani, Tiruchendur): Six lamps are lit at Murugan temples representing the six Krittika stars. Special abhishekam with milk and panchamrit is performed for Murugan on his birth nakshatra day.

- Sri Lanka Tamil Tradition: Tamil communities in northern and eastern Sri Lanka observe Karthigai Deepam with the same lamp-lighting traditions as in Tamil Nadu, with Nainativu Nagapooshani Amman Temple being a key site.
