Why We Celebrate Diwali: The Stories Behind the Five Days

On Diwali evening, in homes from Varanasi to Pune, a child crouches at the threshold beside a row of clay lamps and asks the question every family hears sooner or later: why do we light them? A grandmother says Lakshmi is coming. An uncle says Rama has come home. Someone else says Krishna has won. The child, quite reasonably, wants to know which one is true, and how a single night can belong to three stories at once.

So why is Diwali celebrated? Because each of its five days remembers a different story. Dhanteras recalls Dhanvantari rising from the churned ocean with the nectar of immortality (amṛta). Narak Chaturdashi recalls Krishna’s victory over the demon king Naraka. Diwali night belongs to Lakshmi, who rose from the same ocean and chose Vishnu, and, across North India, to Prabhu Ram’s return to Ayodhya. Govardhan Puja recalls Krishna lifting the hill to shelter Vraja, and Bhai Dooj recalls Yamuna welcoming her brother Yama. The Bhagavata Purana and the Valmiki Ramayana tell most of these stories; the days on which families keep them come from tradition. For the puja itself and the 2026 muhurta, see our Diwali puja vidhi guide.

Why Is Diwali Celebrated?

Diwali in 2026 runs from Friday 6 November to Wednesday 11 November in India, and each day carries its own story. The table gives the day, its date this year, the story it remembers, and where that story is told.

The dates follow the Indian calendar for 2026. Lakshmi Puja timings for Delhi, the Netherlands, Australia, and the United States are in the Diwali 2026 date and muhurta section of our guide. The days are named here by their place around the Diwali new moon, not by month, because the month changes with the calendar a region follows. The five days do not fall on five consecutive dates this year, because each follows its own lunar-day rule, and regional calendars can differ by a day; the guide explains why.

Dhanteras: Dhanvantari and the Churning of the Ocean

The first story is the longest, and it begins with the gods in trouble. The Bhagavata Purana (Book 8, chapters 6 to 8) tells how the gods, weakened and in need of the nectar, agreed to churn the ocean of milk together with the demons, the story known as the Samudra Manthan.

On Vishnu’s counsel, Mount Mandara became the churning rod and the serpent Vasuki the rope (8.6.22). When the mountain began to sink, Vishnu took the form of a vast tortoise and held it up on his back (8.7.8 to 9). The first thing to rise was the deadly poison halahala, and Shiva, out of compassion, drank it from his palm to save the worlds; it turned his throat blue (8.7.18 and 8.7.42 to 43).

Then the treasures came, one by one: the wish-fulfilling cow Surabhi, the horse Uchchaihshravas, the elephant Airavata, the Kaustubha gem, the Parijata tree, and the celestial dancers (8.8.1 to 7). Lakshmi rose next, and her story follows below. Last of all came Dhanvantari, a portion of Vishnu himself, carrying the pot of nectar in his hands. The text names him and calls him the knower of the science of life (āyurveda) (8.8.31 to 35).

Tradition keeps Dhanvantari’s appearance on the thirteenth lunar day (trayodaśī) of the waning fortnight, two days before the Diwali new moon, which is why Diwali opens with Dhanteras. The name, also given as Dhanatrayodashi, is commonly explained as dhana, wealth, with teras, the thirteenth, and many households buy a new metal vessel or a little silver on this day. Yet the story behind the day puts health first. Before the week turns to fortune, it begins with the physician of the gods, holding the one treasure without which no other can be enjoyed.

Many families also set a lamp at the door on Dhanteras evening, facing south, for Yama, the lord of death, as a prayer for the household’s long life. It is household custom rather than a story from the texts, and it quietly links the first night of Diwali to the last.

How Lakshmi First Appeared

Lakshmi rose from the same churning, after the celestial dancers and before Dhanvantari, and the Bhagavata Purana tells her coming with great tenderness (8.8.8 to 25). She lit up every direction with her radiance, and every being, god, demon, and human alike, longed for her.

Indra brought her a seat. The rivers, in embodied form, brought pure water in golden pots for her consecration, the sages performed it, and the elephants of the directions bathed her. The ocean gave her garments of yellow silk, and Varuna the Vaijayanti garland. Then, with a garland of lotuses in her hand, she set out to choose.

She found something missing in everyone she saw. One had austerity but had not conquered anger; another had knowledge but was not free of attachment; another was great but had not conquered desire. One had long life but not an auspicious character; another had virtue but no certainty of life. Only Vishnu held every virtue and needed nothing from her, so she chose him. She placed the garland on him, and he gave her his chest as her permanent home (8.8.20 to 25). The demons, passed over, lost their strength and their spirit.

The story carries much of the meaning of Lakshmi Puja. Fortune is drawn to the one who is steady and complete, and she does not stay where greed and restlessness live. Families act out the same idea when they clean the house, settle their accounts, and light it fully before inviting her in on Diwali night. Why Ganesha is worshipped beside her is explained in our guide’s section on why Lakshmi and Ganesh are worshipped together.

Narak Chaturdashi: Krishna and Narakasura

The Bhagavata Purana (Book 10, chapter 59) tells of Naraka, son of the Earth goddess, who grew so proud that he seized the umbrella of Varuna, the earrings of Aditi, mother of the gods, and Maniparvata, the gods’ own mountain. Indra came to Dvaraka to ask for help, and Krishna rode out on Garuda with his queen Satyabhama beside him.

Krishna broke the city’s defences and slew Naraka. The Earth goddess herself then returned the stolen treasures and placed Naraka’s frightened son at Krishna’s feet, and Krishna gave the boy his protection. In Naraka’s palace he found 16,100 young women held captive; he freed them and sent them to Dvaraka with honour. In some regional retellings Satyabhama strikes the final blow herself; in the Bhagavata, Krishna does.

The text does not name the day, but tradition keeps this victory on Chaturdashi, the fourteenth lunar day, the last before the Diwali new moon, and much of South India celebrates Deepavali itself on this morning. The oil bath before sunrise (abhyaṅga snāna) is the household’s own small victory: the body washed clean before the night of lamps. In 2026 the bath falls before sunrise on Sunday 8 November.

The Bhavishya Purana gives the bath a second reason. Krishna tells Yudhishthira to bathe at dawn on this fourteenth to remove the fear of naraka, hell, to offer water to Yama under his seven names, and then to light lamps.

Diwali Night: Prabhu Ram Returns to Ayodhya

In the Valmiki Ramayana (Yuddha Kanda, sargas 127 and 128 in the common numbering), Rama returns to Ayodhya after fourteen years of exile and the war in Lanka. Bharata, who had ruled only as his brother’s caretaker, orders the city made ready. The road from Nandigrama is levelled and sprinkled with water, flowers and parched grain are scattered, flags fly over every house, and the deities in the temples are worshipped with music and fragrant flowers. Rama is then crowned king.

In his account of the return, Valmiki mentions no lamps, and he gives no day. The picture of Ayodhya glowing with rows of lamps to welcome Rama home belongs to the living tradition, especially in North India, which keeps Diwali night as his homecoming. The text gives the welcome; the families who remembered it gave the lamps. The Bhavishya Purana describes those lamps directly: lamp trees lit at dusk on the Kartika new moon, and, after midnight, the women of the house driving misfortune (Alakshmi) out with winnowing baskets.

So two stories share one evening. Lakshmi is worshipped because fortune, in her own story, settles only with the steady and complete; Rama is welcomed because the rightful king has come home. Both are stories of order restored, and a lit house says the same thing in both: the household is ready.

Govardhan Puja and Bali Pratipada

The first lunar day of the bright fortnight after the Diwali new moon (pratipadā) remembers two stories of shelter. The Bhagavata Purana (Book 10, chapters 24 and 25) tells how the people of Vraja were preparing their yearly offering to Indra, the god of rain. The young Krishna reminded them that they were forest people, whose home was the woods and the hills, and asked that everything gathered for Indra be offered instead to the cows, the Brahmins, and Govardhan hill (10.24.24 to 30).

Indra, insulted, sent a storm to flood Vraja. Krishna lifted Govardhan with one hand, as easily as a child lifts a mushroom (10.25.19), and held it up for seven days without moving a step, sheltering every family and every animal beneath it (10.25.23).

The mountain of food offered on this day (annakūṭa) recalls the feast Vraja first offered to the hill, every dish from sweet rice and halwa to puris (10.24.26). In Gujarat, the same day opens the new year.

Notably in Maharashtra and Karnataka, the day honours King Bali, the generous demon king. The Bhagavata Purana tells how Vishnu, as the dwarf Vamana, asked him for just three steps of land, measured by his own small feet (8.19.16). Vamana covered all the worlds in two steps (8.21.29); for the third, Bali bowed and offered his own head (8.22.2), and Vishnu, pleased, sent him to rule the realm of Sutala (8.23.3). Tradition holds that Bali returns to visit his people on this day. Krishna shelters a village under a hill; Vishnu takes a king’s whole world and then gives him a kingdom of his own. Both stories end with the humbled made safe.

Bhai Dooj: Yama and Yamuna

The last day is also called Yama Dvitiya, after the second lunar day (dvitīyā) of the bright fortnight, on which it falls. Tradition tells that Yamuna had long invited her brother Yama, the lord of death, to her home, and on this day he finally came. She welcomed him with a tilak, a lamp, and a meal, and Yama, moved, granted that any brother who visits his sister on this day and receives her welcome would be free from the fear of untimely death. Sisters still mark a brother’s forehead and feed him from their own kitchen, and brothers still bring a gift.

So Diwali ends where it began, with a prayer for long life: Dhanvantari’s nectar and the lamp for Yama at the door on the first evening, and a sister’s blessing on the last.

Kali on Diwali Night

In Bengal, Assam, Tripura, Odisha, Bangladesh, and the Anga region of Bihar, the same new-moon night belongs to Kali, worshipped at midnight. The two are not rival festivals. The Durga Saptashati names the Goddess herself as the Night of Time (kālarātri), and tradition reads that night as this new moon; Kali’s name and the night share the word kāla, time. North and West India worship the Goddess as Lakshmi on this night, and the East as Kali.

A Tantra from about 1600, the Shakti Sangama Tantra, is more exact. In its Kali Khanda, Shiva names the great nights of the Goddess and calls the night when the fourteenth of the lamp festival meets the new moon Kalaratri, “dear to Tara and Kali”. The same chapter names Janmashtami as Moharatri, but gives Maharatri to the eighth night of the Ashvina Navaratri, not to Shivaratri. In Bengal, the night is closely tied to Dakshineswar, the Kali temple opened on the Hooghly in 1855, where Sri Ramakrishna served as priest from its first years. For him, Kali was the living Mother of the universe, and the lamp, the flowers, and the midnight worship were offered to her as a child offers to his mother. Our guide explains the link in full in Kali Puja: Diwali Night as Kalaratri.

What the Five Stories Share

Back at the threshold, the child’s question has an answer, and it is not “pick one”. The five days move in a telling order. Dhanteras begins with health: Dhanvantari and the nectar. Narak Chaturdashi brings freedom from darkness, as Naraka’s prisoners walk out into the light. Diwali night brings prosperity and rightful order: Lakshmi chooses the one who needs nothing, and Rama comes home. Govardhan Puja brings shelter, a hill held over a village for seven days and a humbled king given a realm of his own. Bhai Dooj ends with family, a sister’s welcome and a prayer for her brother’s long life.

The texts supply each story on its own. The Bhagavata Purana tells the churning, Naraka, Govardhan, and Vamana; the Valmiki Ramayana tells Rama’s welcome. None of them binds the five into one week. Tradition did that, over centuries, by giving each story its lunar day around the Diwali new moon and lighting a lamp for each.

So the grandmother, the uncle, and whoever spoke of Krishna were all right. The lamps are lit for every one of them.

Frequently Asked Questions

What is the real story behind Diwali? There is no single story. Each of the five days keeps its own: Dhanvantari on Dhanteras, Krishna’s victory over Naraka on Narak Chaturdashi, Lakshmi and Rama’s homecoming on Diwali night, Govardhan on the day of Govardhan Puja, and Yama and Yamuna on Bhai Dooj.

Is Diwali celebrated for Rama or for Lakshmi? For both, on the same night. Lakshmi Puja is the night’s worship across most of India, while North Indian tradition also keeps Diwali as the night Rama returned to Ayodhya. The two stories sit side by side; neither replaces the other.

Does the Ramayana mention lamps for Rama’s return? No. In his account of the return, Valmiki describes the road levelled and sprinkled with water, flowers and parched grain scattered, and flags on every house, but no lamps and no date. The lamps of Ayodhya come from the living tradition that remembered the homecoming.

Why is Dhanteras celebrated? Dhanteras celebrates Dhanvantari, the physician of the gods, who rose from the churned ocean carrying the pot of nectar. Tradition keeps his appearance on the thirteenth lunar day before the Diwali new moon, so the festival begins with health before it turns to wealth.

What is the story of Govardhan Puja? Krishna persuaded the people of Vraja to offer their yearly worship to Govardhan hill instead of Indra. Indra answered with a flooding storm, and Krishna lifted the hill and held it over Vraja for seven days. The Annakut offering recalls the feast first offered to the hill.

Why is Bhai Dooj celebrated? Bhai Dooj remembers Yama visiting his sister Yamuna, who welcomed him with a tilak, a lamp, and a meal. Tradition says Yama blessed every brother who visits his sister on this day with freedom from the fear of untimely death.
