Most ghee diyas that go out early were never going to stay lit. The problem is almost never the ghee — it is a dry wick, dropped straight into the diya and lit.
A batti soaked in ghee before you light it burns steadily for hours. One that is not will sputter, smoke and die within minutes, usually right in the middle of the puja.
Diwali 2026 falls on Sunday, 8 November, with the Lakshmi Puja muhurat around 5:54 PM to 7:50 PM in Delhi, in the Pradosh Kaal after sunset. Timings shift by city, so check your local panchang.
Here is how to prepare a ghee diya properly, where to place them, and how to do it safely.
Why Ghee Diyas Are Used at Diwali
Lighting a lamp is the oldest part of Diwali — older than the sweets, the shopping and the crackers. The festival's name comes from deepavali, a row of lamps.
Ghee has been the traditional fuel in household puja for practical reasons as much as ritual ones. It burns with a steady flame, produces noticeably less smoke and soot than many oils, and carries a mild dairy aroma rather than a sharp one — which matters in a small mandir or a closed room.
Cow ghee is what most households use for the puja lamp specifically, with oil diyas used more freely around the rest of the house.
The Diya in Lakshmi Puja
On Diwali night the lamps are not only decorative. They are an invitation.
Doors and windows are opened and diyas placed at thresholds, windowsills and balcony ledges to welcome Lakshmi into the home. The puja itself is performed in the Pradosh Kaal, after sunset, with the main diya lit before the puja begins and kept burning through it.
In many households the main lamp is kept alight through the night rather than extinguished when the puja ends. Customs vary considerably by family and region.
Ghee Diya vs Oil Diya
| Point | Ghee diya | Oil diya |
|---|---|---|
| Traditional use | Common in puja and festive rituals | Also widely used |
| Flame | Usually steady when prepared properly | Depends on the oil and wick |
| Smoke | Generally less soot | Varies; mustard and sesame are common |
| Aroma | Mild dairy aroma | Depends on the oil |
| Best use | Lakshmi Puja, home mandir, festive rituals | Entrance, balcony, railings, decoration |
| Choice | Based on family tradition | Based on family tradition |
In practice most families use both, and the division is sensible rather than hierarchical: ghee for the puja thali and the mandir, where the flame is close and the room is enclosed, and oil for the dozens of diyas lining the entrance and balcony, where you need volume and the wind is the bigger problem.
How to Prepare a Ghee Diya, Step by Step
- Choose the wick. A long cotton batti for regular diyas, or a round one for a diya meant to burn longer. Hand-rolled cotton works as well as ready-made.
- Soak the wick in ghee first. This is the step that decides everything. Dip the batti in melted ghee and let it absorb fully before it goes near a flame. A dry wick burns itself out instead of drawing the ghee up.
- Fill the diya about three-quarters with ghee. If your ghee has set firm in winter, warm it slightly so it pours.
- Position the wick so it rests on the lip or spout with the tip sitting just above the ghee level. Too deep and it drowns; too far out and it burns down fast.
- Trim the tip if it looks frayed, then light it.
- Top up at the side as the level falls, without disturbing the flame. Never pour ghee directly onto a burning wick.
How Much Ghee, and How Long It Burns
A small diya holding roughly 15 to 20 ml of ghee burns for about three to four hours with a standard cotton batti. That covers a Lakshmi Puja evening comfortably.
For a lamp meant to last the night, use a deeper diya and expect to top it up once. A thicker wick gives a larger flame and burns through the ghee faster, so for duration, a moderate wick in a wider diya is steadier than a thick wick in a small one.
If you are lighting many diyas across the five days, that adds up — our pack size guide covers how much to buy.
Where to Place Diyas During Lakshmi Puja
- The home mandir or puja thali — the main ghee diya, lit before the puja begins
- Both sides of the main entrance — the threshold matters most on Diwali night
- Windowsills and balcony ledges — doors and windows are traditionally left open
- The tulsi plant, where the household keeps one
- The kitchen, and near the water source — tap, well or water storage
- Corners of rooms and along stairways, as space allows
Many families light diyas in odd numbers. On Dhanteras, a lamp is traditionally placed facing south outside the home as the Yama deepam. Practices differ by region and household.
When to Light Them
Diyas are lit at dusk, after sunset, in the Pradosh Kaal — which in 2026 puts the Lakshmi Puja window around 5:54 PM to 7:50 PM in Delhi.
Light the main puja diya first, then the rest of the house from it. Check your city's muhurat rather than using a Delhi timing, since sunset varies by well over half an hour across India.
Safety Tips Worth Taking Seriously
Diwali is the one night of the year with open flames in every room of the house, often alongside synthetic clothing and paper decorations.
- Keep diyas well clear of curtains, torans, paper decorations and rangoli made with loose powder
- Watch dupattas and lehengas. Synthetic fabric catches very quickly, and bending over a lit diya is how most Diwali burns happen
- Place diyas on a stable, flat, non-flammable surface — a steel plate or tile, not directly on cloth or a wooden ledge
- Never pour ghee onto a lit diya. Extinguish it, top it up, then relight
- Keep them out of reach of children and pets, and away from where people walk
- Metal diyas get hot. Use a plate or coaster underneath
- Keep flames far from crackers, phuljhadi and aerosols
- Never leave a burning diya unattended in a room with anything flammable, and keep water within reach
Why Some Families Prefer Pure Desi Ghee
For the puja lamp specifically, the reasons given are usually the steadier flame, the lower smoke in an enclosed mandir, and the aroma — plus the simple fact that it is what the family has always used.
Worth saying plainly: no form of ghee is ritually superior to another, and an oil diya is not a lesser offering. This is a question of household tradition, not of rules.
Where Kasutam Fits
Kasutam A2 Desi Cow Bilona Ghee is made from the milk of indigenous Rathi cows by the curd-churned bilona route: Rathi cow milk → curd → makkhan → ghee.
Being cow ghee, it suits the puja diya as well as the prasad — and the same jar carries into the Diwali mithai and the festive meals across the five days.
Conclusion
A good ghee diya is mostly preparation. Soak the wick, fill the diya three-quarters, rest the batti on the lip with the tip clear of the ghee, and top up at the side rather than over the flame.
Then place them where they are safe as well as where they look right, light them after sunset, and keep an eye on the dupattas.
Shubh Deepavali.
Frequently Asked Questions
Why is ghee used in diyas during Diwali?
Ghee has traditionally been the fuel for household puja lamps because it burns with a steady flame, produces less smoke and soot than many oils, and carries a mild aroma rather than a sharp one — which matters in an enclosed mandir. Cow ghee is what most households use for the puja lamp, with oil diyas used more widely around the rest of the house.
Can pure desi ghee be used for the Lakshmi Puja diya?
Yes. Pure desi cow ghee is what most families use for the main puja lamp. No form of ghee is ritually superior to another, and an oil diya is not a lesser offering — it is a matter of household tradition rather than rule.
How do you make a ghee diya for Diwali?
Soak a cotton batti in melted ghee until it absorbs fully — this is the step that decides whether the diya stays lit. Fill the diya about three-quarters with ghee, rest the wick on the lip or spout with its tip just above the ghee level, trim any frayed end, and light it. Top up at the side as the level falls, never over the flame.
Where should diyas be placed during Lakshmi Puja?
The main ghee diya goes in the home mandir or on the puja thali. Others are placed at both sides of the main entrance, on windowsills and balcony ledges, by the tulsi plant, in the kitchen, near the water source, and in corners and stairways. Many families light them in odd numbers, and practices vary by region.
Is a ghee diya better than an oil diya?
Neither is better — they suit different places. Ghee burns steadily with less smoke, which makes it the usual choice for the puja thali and the mandir where the room is enclosed. Oil diyas are practical in volume for the entrance, balcony and railings, where you need many lamps and wind is the bigger problem. Most households use both.
