Diwali : How Did a Simple Harvest Festival Evolve into India’s Biggest Celebration?

KAKALI DAS

Diwali, the festival of lights, today stands as the brightest symbol of India’s unity, joy, and cultural richness. Homes are lit with lamps, markets glow with colours, sweets are exchanged, and photographs are taken to capture the spirit of festivity. Yet, what we see today as a grand celebration did not emerge overnight. The Diwali we know has been shaped by over three thousand years of faith, transformation, and shared history. It began as a humble harvest festival and grew through centuries into a celebration that reflects the very soul of India.

In its earliest form, Diwali, or Deepavali which means a row of lamps, was a festival of farmers. Long before it became linked to gods or mythology, it was celebrated as a thanksgiving to nature. Farmers lit small lamps at the end of the harvest season to thank the Sun for its life-giving energy and to seek blessings for the next cycle of crops. These lamps symbolised renewal, purification, and gratitude.

Ancient texts like the Skanda Purana mention the practice of lighting lamps during this period. Another Purana that refers to Deepavali is the Padma Purana. Many scholars such as Pankaj Jain and Venny The Nagar describe this early Diwali as a practical and spiritual event rather than a religious one. It was a time when people used light to keep away insects after the rains and to invite prosperity into their homes. The act of lighting lamps carried both meaning and purpose, connecting people to the rhythms of the earth and sky.

As centuries passed, Diwali began to take new forms. Around the sixth century BCE, it gained a deep spiritual meaning for the Jain community. For Jains, Diwali marks the Nirvana or liberation of Lord Mahavira, the twenty-fourth Tirthankara, who attained enlightenment at Pavapuri in 527 BCE. Early Jain texts like Kalpasutra and LoykaPannatti mention this sacred event. The lighting of lamps symbolised Mahavira’s spiritual light that continues to guide humanity. It represented knowledge, purity, and liberation from ignorance. Thus, Diwali for the Jains became not just a festival of light but also a celebration of the soul’s victory over darkness.

With time, Diwali found another layer of meaning through the great Indian epic, the Ramayana. The return of Lord Rama, his wife Sita, and his brother Lakshmana to Ayodhya after fourteen years of exile became a central story of the festival. To welcome them, the people of Ayodhya lit lamps throughout the kingdom, turning the dark night of Amavasya into one of light and joy. This tale became the most enduring image of Diwali, symbolising the triumph of good over evil, truth over falsehood, and righteousness over injustice.

Literary works like Adhyatma Ramayana and Ramcharitmanas by Tulsidas expanded this association, particularly during the Bhakti period, when devotion became the heart of worship. While Valmiki’s original Ramayana does not mention Diwali directly, the later devotional retellings added emotion and devotion to the festival. Temples in cities like Ayodhya, Varanasi, and Madurai began performing Deep Daan rituals, where thousands of lamps were lit to honour Lord Rama and Goddess Lakshmi.

During the medieval period, Diwali started moving beyond temples and royal palaces. It became a festival of the people. Kings and merchants celebrated it as a mark of prosperity. The Bhakti movement added warmth and inclusivity, turning Diwali into both a religious and social occasion. In Bengal, it merged with the worship of Goddess Kali, while in Gujarat it became linked with Goddess Lakshmi and new beginnings in business. The festival gradually took on regional colours, reflecting India’s cultural diversity while keeping its central theme of light and renewal.

In the seventeenth century, Diwali took on another dimension with the Sikh community. For Sikhs, the day coincides with BandiChhor Divas, meaning the Day of Liberation. Guru Hargobind Singh, the sixth Sikh Guru, was released from Gwalior Fort in 1619 along with fifty-two kings whom he helped free.

The Harmandir Sahib, or Golden Temple, in Amritsar was lit up with lamps to celebrate his return. This tradition continues today, with thousands of lamps and fireworks illuminating the sacred shrine. The Mughal emperor from whose custody Guru Hargobind was released was Jahangir. The celebration became a symbol of freedom, moral courage, and unity across faiths. Diwali now stood not only for the victory of good but also for the triumph of justice and liberation.

As time moved into the colonial and modern periods, Diwali grew beyond India’s borders. The festival was celebrated in royal courts, among traders, and later in towns and cities across the subcontinent. Business communities began observing Chopda Pujan, a ritual of closing old account books and opening new ones to mark the beginning of the financial year. Dhanteras, the day before Diwali, evolved as a festival dedicated to wealth and prosperity. Fireworks, fairs, and sweet-making became integral parts of the celebration. British colonial records mention grand Diwali festivities in cities like Calcutta, Bombay, and Delhi. In Bengal, Kali Puja became the night of fierce devotion, while in other regions, lamps and lights became the mark of joy and unity.

With independence and modernization, Diwali entered the age of cinema, media, and global migration. Bollywood made it a visual symbol of family, togetherness, and triumph. In the twenty-first century, Diwali is celebrated across more than fifty countries, from the streets of London and New York to the temples of Singapore and Durban. Governments and cities across the world now recognise Diwali as a cultural holiday. The lights that once flickered in small farming villages now shine across continents.

The festival has also evolved with time. Today, there is growing awareness about eco-friendly celebrations and sustainable practices. People are shifting toward earthen lamps instead of electric lights and choosing green crackers or symbolic lightings instead of heavy fireworks. This change reflects a new understanding of responsibility towards nature, a return to the purity with which the festival once began.

Diwali’s beauty lies in its diversity. It is celebrated differently across India, yet its essence remains the same, the victory of light over darkness and hope over despair. In North India, Diwali is closely tied to Lord Rama’s return to Ayodhya. Cities like Delhi, Uttar Pradesh, and Bihar are filled with the fragrance of marigolds and the glow of diyas. The banks of the Saryu River in Ayodhya are perhaps the most spectacular sight of all. Every year, the ghats are lit with millions of lamps, turning the river into a sea of gold. In Varanasi, the city of Shiva, Diwali becomes Dev Deepavali, the festival when gods themselves are believed to descend to Earth to bathe in the Ganga. The ghats sparkle with countless lamps, and the air vibrates with chants, fireworks, and music.

In the eastern parts of India, especially West Bengal and Assam, Diwali takes the form of Kali Puja. Devotees worship Goddess Kali, the fierce protector who destroys evil and restores balance. Temples and pandals are decorated with intricate designs, and offerings are made to seek her blessings. In Odisha, the festival takes a unique form called BadabaduaDaka. People light joss sticks and lamps to honour their ancestors and seek their guidance and protection. The festival here is as much about remembrance as it is about renewal.

In western India, Diwali holds deep cultural and economic importance. In Gujarat, it marks the New Year according to the VikramSamvat calendar. Known as NutanVarsh, this day is celebrated by merchants and business families as a time to close old accounts and start new ledgers. Goddess Lakshmi, the deity of wealth, is worshipped, and prayers are offered for prosperity. The lighting of diyas in homes and shops reflects both devotion and discipline.

In Maharashtra, Diwali begins with Vasu Baras, a day dedicated to the worship of cows. The cow, regarded as a symbol of motherhood and nurturing, is bathed, decorated, and offered food. Families exchange sweets and gifts, marking the beginning of the festive week. Moving to the coastal state of Goa, Diwali has yet another flavour. Here, it is known as Narkasur Chaturdashi. Huge effigies of the demon king Narakasura are built and burned at dawn, symbolising the destruction of evil by Lord Krishna. The event fills the air with music, laughter, and fireworks, creating an atmosphere of unity and celebration.

This wide diversity in customs and stories is what makes Diwali truly Indian. It carries the spirit of unity in diversity that defines the country. Each region, community, and generation has added its own meaning and emotion to the festival, shaping it into a mosaic of faiths and traditions. Whether it is Mahavira’s Nirvana, Lord Rama’s return, or Guru Hargobind’s freedom, each story adds light to the larger meaning of Diwali.

In modern India, Diwali continues to bind people together. It is a moment when streets, temples, and homes glow in unison, when hearts open, and when differences blur. It is a reminder that light, both physical and spiritual, has the power to overcome every form of darkness. From the humble oil lamp of the ancient farmer to the grand illuminations across global cities, Diwali’s flame has never gone out. It burns in every home, every tradition, and every hope that India carries forward.

Diwali, therefore, is not just a festival. It is the story of India itself, a story of change and continuity, faith and freedom, simplicity and splendour. It began in the fields and now shines across the world, carrying with it the timeless message that light will always find its way through the dark.
