pujas and observances
What is a Deepa puja (lamp worship) and what are the rules for different types of lamps used in Hindu ritual?
The lamp as an offering
In Hindu worship, the lit lamp is one of the core offerings made to a deity. It appears as part of the Shodashopachara, the sixteen-step offering sequence used in formal puja. The flame stands for light, knowledge, and the divine presence. Lighting the lamp is not just a practical act. It is itself an act of devotion. The Puranic tradition, including texts like the Agni Purana and Skanda Purana, treats the lamp with great care and gives guidance on how it should be prepared and used.
Which oil for which purpose
The tradition distinguishes clearly between oils. Ghee, clarified butter, is widely seen as the most auspicious choice and is linked to prosperity and general worship. Sesame oil is traditionally used for Shiva worship and for lamps lit for ancestors, making it common during shraddha rituals and on days connected to the departed. In South India, coconut oil is the everyday choice for home lamps and temple lamps, and it is deeply embedded in regional practice. Castor oil also appears in some traditions, particularly for certain deity forms. The choice of oil is not just regional habit. The tradition holds that different oils carry different qualities and reach different purposes.
Single wicks, multiple wicks, and the Pancha Deepa
The number of wicks matters too. A single-wick lamp is the most common form for daily home worship. The Pancha Deepa, a lamp with five wicks, is used in more formal or festive settings. Five is a number with ritual weight in many Hindu ceremonies, and the five flames together are seen as more powerful as an offering. Some lamp forms have specific uses in temple ritual and are not typically part of simple home worship. The material of the lamp also varies. Clay diyas are common and considered pure. Brass and copper lamps are used in more permanent household shrines and temples.
One rule almost everyone knows
Across regions and traditions, one rule is held very widely: never blow out a lamp with your breath. The breath is seen as impure in this context, and extinguishing a sacred flame that way is considered disrespectful. Instead, the flame is fanned out gently with the hand or with a small fan, or simply left to burn out. This is one of the most consistent customs around lamp use in Hindu ritual.
How it looks today
In homes around the world, the daily lamp at the household shrine is often the simplest form of puja, even when a full ritual is not possible. Many families light a ghee lamp or a coconut oil lamp at dawn and dusk as a steady rhythm of the day. Which oil is used often follows what the family grew up with, shaped by regional background. The rules around lamps are passed down through practice more than through text, so they vary between households and communities.
