Karthika Deepam Pooja: A Festival of Lamps and Devotion to Shiva and Vishnu
By Divine Center ·
Thinking of doing Karthika Deepam Pooja? Know what this lamp festival ritual is, what happens during the Karthika month, and what families do during this sacred period.
What is Karthika Deepam Pooja?

Karthika Deepam Pooja is a series of rituals and observances done during the Karthika month - the eighth month in the Hindu lunar calendar, usually falling between October and December. It is one of the most sacred months in South Indian tradition, particularly in Andhra Pradesh, Telangana, Karnataka, and Tamil Nadu.
The central act of this period is lighting lamps - deepam - every evening at dusk. Lord Shiva and Lord Vishnu are both worshipped during Karthika month, which is rare - most months are associated with one deity. Karthika is considered especially powerful for both Shaivites and Vaishnavas.
The Karthika Deepam festival on the full moon day - Karthika Purnima - is the peak of this month, when a large lamp is lit atop the Tiruvannamalai hill in Tamil Nadu as the Arunachala Deepam. Families across South India light lamps at home and in temples on this day.
When and How is Karthika Deepam Observed?
Every evening through the Karthika month : Families light a lamp - traditionally with ghee or sesame oil - in front of the Tulsi plant at home every evening. This is the core daily practice of Karthika month and is considered enough on its own as a daily offering.
Karthika Somavar - Mondays in Karthika : Mondays during the Karthika month are particularly sacred for Shiva worship. Many devotees observe a fast, visit Shiva temples, do Shiva abhishekam with milk and bilva leaves, and light lamps in the evening.
Karthika Purnima : The full moon day is the most important day of the month. Families do a special puja at home, light multiple lamps around the house and Tulsi plant, visit the nearest river or tank for a holy dip at dawn, and offer prayers at the temple. In many families, this is the day the Karthika Deepam Pooja is done formally with a pandit.
Skanda Shashthi during Karthika : Lord Murugan's birthday falls during the Karthika month. Tamil families in particular observe Skanda Shashthi with fasting and special puja during this period.
What Happens During the Formal Puja?
When a family does a formal Karthika Deepam Pooja at home - usually on Karthika Purnima or a chosen Monday - the pandit begins with Ganesh puja followed by a Shiva puja with bilva archana and abhishekam.
A Tulsi puja is done - Tulsi, the sacred basil plant, holds special significance during Karthika month and is worshipped alongside Lord Vishnu. The pandit then performs a deepotsavam - a ceremonial lighting of multiple lamps - while chanting Karthika Deepam mantras and the Shiva Panchakshara and Vishnu Ashtakshara mantras.
Families light 108 lamps around the house, the Tulsi plant, and the puja room as part of the ritual. The overall puja takes 1.5 to 2.5 hours.
Questions Families Commonly Ask
Q) Is Karthika Deepam Pooja only for South Indians?
It is most widely observed in South India - particularly in Telugu, Kannada, and Tamil communities. But the significance of Karthika month and the practice of lighting lamps for Shiva and Vishnu is recognized across Hindu traditions. Anyone can observe it regardless of regional background.
Q) Can it be observed without a pandit?
Yes. The daily lamp lighting and Tulsi puja during Karthika month is done entirely by the family without a pandit. A pandit is called for the formal puja on Karthika Purnima or a specific Monday if the family wants a structured ritual with mantras and abhishekam.
Q) What is the significance of lighting lamps specifically?
In Hindu tradition, the lamp represents the removal of darkness - both physical and spiritual. Lighting a lamp during Karthika month is believed to remove sins accumulated over time, bring peace to the household, and please both Shiva and Vishnu simultaneously. The consistent daily act of lighting that lamp - every evening, through the entire month - is considered a powerful spiritual practice in itself.
Q) What is the Tulsi Vivah connection?
Tulsi Vivah - the ceremonial marriage of the Tulsi plant to Lord Vishnu - is also observed during the Karthika month, usually on Karthika Dwadashi or Purnima. Many families combine Tulsi Vivah and Karthika Deepam Pooja on the same day. The pandit can perform both rituals together if you want.
Q) Is a river dip mandatory on Karthika Purnima?
Traditionally, taking a dip in a sacred river or tank at dawn on Karthika Purnima is considered very auspicious - specifically in rivers like the Godavari, Krishna, or Kaveri. But if you are not near a sacred river, a head bath at home before sunrise with a prayer is the equivalent practice followed by most urban families.
What Karthika Month Feels Like in a Hindu Home
There is something distinct about a home during Karthika month. The lamp lit at dusk every evening, the smell of ghee or sesame oil, the Tulsi plant decorated with a small diya - it creates a rhythm in the house that is hard to describe but easy to feel.
For many families, Karthika month is the one time of year when the daily puja feels less like a task and more like something the whole family does naturally together. The simplicity of it - just a lamp, just a flower, just a few minutes at dusk - is what makes it sustainable through the entire month.
And on Karthika Purnima, when the 108 lamps are lit and the whole house is glowing, that evening stays with people for a long time.
