Lighting an oil lamp (diya or deepam) is one of the most cherished parts of Hindu worship — in daily puja, at festivals like Diwali and Karthika Deepam, and on every auspicious occasion. Far from a mere ritual, it carries deep symbolism.
The Symbolism of Lighting a Lamp
- Light symbolises knowledge, wisdom and positivity.
- Darkness symbolises ignorance.
- The flame represents the soul (atma) and the divine presence.
- The oil or ghee represents our negative tendencies and ego.
- The wick represents the mind/body — as the wick is consumed, the ego is offered up so the light of awareness can shine.
When we light a lamp, we symbolically dispel the darkness of ignorance and invite the light of knowledge — "Tamaso mā jyotirgamaya" (lead me from darkness to light).
A Calm, Sacred Atmosphere
The soft, steady glow of a lamp naturally creates a peaceful, meditative mood that helps the mind settle for prayer. This is a matter of devotional atmosphere and focus, valued in our tradition — not a medical claim.
Types of Lamps Used in Hinduism
- Ghee lamp — for daily puja and special rituals.
- Sesame-oil lamp — for daily worship.
- Clay diya — for Diwali and festivals.
- Brass/silver lamp — for daily and temple use.
- Akhanda Deepam — a continuously burning lamp, often in temples.

- At weddings, housewarmings and other auspicious occasions.
