Why Is a Lamp Placed in the South Direction on Dhanteras?

On Dhanteras, most families pray to Goddess Lakshmi and Lord Kubera for wealth and prosperity. But there is another traditional ritual that turns attention towards something money cannot buy: life itself. Known as Yam Deepam, this practice involves lighting a lamp for Yama, the deity associated with death, on Dhanteras evening. Why is the lamp traditionally placed outside the home, facing the south? And what do its four wicks represent? The answers lie in an old belief about protecting the family and praying for a long, healthy life.





While Lakshmi Puja is associated with wealth, Yam Deepam is a prayer for the well-being and long life of family members. In Hindu tradition, Yama is regarded as the deity who governs death and justice. Devotees light a lamp in his honour, seeking blessings against untimely death, known as Akal Mrityu. The ritual carries a simple message: wealth matters, but good health and the safety of loved ones matter even more.





The special lamp used in this ritual is often called a Chaumukhi Diya, meaning a lamp with four faces. All four wicks are lit together as part of the offering to Yama. The four flames make this diya different from an ordinary oil lamp used for daily worship. Families may use sesame or mustard oil, depending on their customs. The main purpose is to offer the light with devotion and pray for the protection, health and longevity of everyone at home.

In Hindu tradition, the south direction is associated with Lord Yama. That is why the Yam Deepam is traditionally placed outside the main entrance with the lamp facing south. The offering is usually made in the evening, around sunset or during the Pradosh period. This direction is not chosen randomly; it reflects the traditional association between Yama and the south. Customs can differ between regions and families, so devotees often follow the method passed down in their household.

To observe the ritual, take a clean four-faced earthen diya and place four cotton wicks in it. Add sesame or mustard oil according to your family tradition, then light all four wicks in the evening. Place the lamp safely outside the main entrance, facing south. Fold your hands and pray to Lord Yama for the good health and long life of your family. Keep the diya away from curtains, dry leaves and other flammable materials, and never leave a burning lamp unattended.

Lighting the lamp is the central act, but devotees may also offer prayers or recite traditional verses dedicated to Yama. Some religious traditions include the recitation of Yama-related prayers, including the Yamashtak. The belief is that remembering Yama with devotion helps reduce fear and brings peace to the mind. However, the exact prayer and method can vary. There is no need to treat any particular recitation as a guarantee that misfortune or death can never occur.

A popular Dhanteras story tells of King Hima's son, whose horoscope predicted that he would die from a snakebite soon after his marriage. His wife refused to give in to fear. On the predicted night, she placed lamps around the entrance, arranged gold and jewellery in a heap, and kept her husband awake with songs and stories. When Yama arrived in the form of a serpent, the bright lights and the sound of her singing kept him from reaching the prince. This story is traditionally linked with the practice of lighting lamps for protection from untimely death.

Dhanteras reminds us that prosperity is not limited to money, gold or expensive purchases. Good health, time with family and the safety of loved ones are also blessings worth being grateful for.
