Butter lamps (Tibetan: mar me) are the Tibetan Buddhist form of the offering of light — lamps traditionally burning clarified yak butter, lit in rows before shrines and images. Their meaning is luminous and simple: light dispels darkness, as wisdom dispels ignorance.

The offering of light is found across Buddhism; the butter lamp itself belongs to the Tibetan and Himalayan world.

Why do Tibetan Buddhists light butter lamps?

Walk into a Tibetan Buddhist temple and you will often meet a wall of soft golden flames — hundreds of small butter lamps, burning steadily before the images. A butter lamp is exactly what it sounds like: a lamp whose fuel is clarified butter, traditionally from the dri (the female yak), with a wick standing in it. Offering these lamps is a devotional act in Tibetan Buddhism, and its symbolism is simple: light overcoming darkness — and, read spiritually, the wisdom that overcomes the darkness of ignorance. As with the whole family of Buddhist symbols, the object is a pointer: the flame is a prayer made visible.

What a butter lamp is

A butter lamp is a small bowl or cup holding clarified butter as fuel, with a wick set upright in the centre. “Traditionally, Tibetans used clarified butter from dri (female yaks), but in exile they use ghee,” the Tibetan Nuns Project writes. Lamps may be lit singly as a daily offering or in great numbers on special occasions. You can light one on screen, with a Tibetan lamp prayer, in our light a lamp tool.

What the butter lamp means

The meaning rests on the oldest of symbols: light against darkness. In Buddhist terms, the darkness is ignorance (avidyā) — the fundamental not-seeing that, in the Buddhist analysis, lies at the root of suffering. The steady flame of the lamp stands for the light of wisdom that dispels it. To offer a lamp is to express the wish that the light of understanding overcome the darkness of confusion — for oneself, and for all beings. Prayers written to accompany the offering of a lamp say so in as many words. Shechen Gyaltsab’s four-line lamp aspiration asks, as the lamp is offered, “may the darkness of our ignorance be dispelled, / And may we obtain the luminous wisdom of omniscience!” The light-offering prayer attributed to Atiśa asks that the lamps’ light banish “the darkness of ignorance everywhere”. And Lama Zopa Rinpoche, in FPMT’s practice booklet, tells students that the brighter the light and the more darkness it dispels, the greater “the inner effect of dispelling ignorance and developing wisdom”.

Light also has a fixed place in the set of offerings laid out on a Tibetan shrine. FPMT’s practice booklet, with instructions by Lama Zopa Rinpoche, gives the row of offering bowls from left to right as water for drinking, water for bathing the feet, flowers, incense, light, perfume, food and music, and notes that the actual flowers, incense, food and “candles or butter lamps” are offered in the bowls themselves, while water stands in for the rest. Offerings are also recited in Sanskrit: in Khenpo Munsel’s short meditation on Akṣobhya the closing offering line runs arghaṃ pādyaṃ puṣpe dhūpe āloke gandhe naivedye śabda, and there too the light offering, āloke, comes fifth. The same word sits in the mantra of the light-offering prayer said to have been chanted by Atiśa and his disciples, oṃ vajrāloke āḥ hūṃ. The butter lamp is that light offering made real (for offerings more widely, see making offerings).

When butter lamps are offered

“It is common to offer butter lamps for those who have passed away or for those who are sick,” the Tibetan Nuns Project writes. “Butter lamps are also lit for happy occasions like birthdays, marriages, and for one’s wishes to come true.” Tibetans also light them, it adds, “on sacred days in the Tibetan Buddhist calendar, such as the 10th, 15th and 25th day of each lunar month, as well as during the holy month of Saga Dawa.”

After a death, many Tibetan centres offer lamps for the 49 days that follow; the Kamalashila Institute, in the Karma Kagyu school, says butter lamps “are traditionally offered for the deceased for 49 days after the person’s death.” The lamps are offered as a wish: Ati Ling, a centre of Chagdud Tulku Rinpoche’s lineage, offers them for the dead “with the wish that they make a positive future connection with a true spiritual path”. And Chagdud Tulku Rinpoche taught: “We do not offer butterlamps because enlightened beings need to see them. Rather, the offering of light is a means of dispelling the darkness of our own ignorance, giving rise to clarity and wisdom.”

Light everywhere, butter lamps in Tibet

One distinction is worth drawing clearly. The offering of light is found across Buddhism. In Sri Lanka, A. G. S. Kariyawasam writes, the Vesak festival “has become more or less a festival of lights”, and a Pali stanza offers a lamp to the Buddha as “a lamp unto the three worlds” (it is in our light a lamp tool, beside a Tibetan prayer). In Japan, a candle festival, Mandokuyoe, is held at Okuno-in on Kōyasan each 13 August “as a memorial service for the spirits of departed loved ones”, as the Wakayama tourism site puts it.

The butter lamp specifically — burning yak butter or ghee — is a Tibetan and Himalayan form, at home in Tibet, Nepal, Bhutan, and the wider Himalayan Buddhist world. So the accurate way to put it is this: offering light is something Buddhists everywhere do; the butter lamp is how the Tibetan world does it. Keeping that line clear is part of honouring each tradition on its own terms.
