In North India, particularly in states like Uttar Pradesh, Punjab, and Rajasthan, Diwali commemorates the return of Lord Rama to Ayodhya after defeating the demon king Ravana. Houses adorn themselves with oil lamps, candles, and vibrant rangolis to honour Lord Rama's homecoming. Celebrations often start with Dhanteras, a day for buying precious metals, followed by Choti Diwali, the main Diwali day, and culminate with Bhai Dooj, celebrating the bond between brothers and sisters. Fireworks are a notable feature, symbolizing the triumph of good over evil.

In cities like Varanasi, devotees also gather along the Ganges for Ganga Aarti, a mesmerizing ritual involving lamps, chants, and prayers. In addition, devotees deep-clean and decorate their homes, and make offerings to Goddess Lakshmi, who is believed to bring prosperity.

Modern-Day Diwali: A Blend of Tradition and Eco-Consciousness

While traditional customs remain central to Diwali celebrations, a growing focus on eco-friendly practices has emerged across India. Many families are now opting for clay diyas instead of plastic lights; plant-based colors for rangolis; and even eco-friendly fireworks. Additionally, some regions have adopted silent or reduced-noise Diwali practices to protect animals and reduce air pollution.

Diwali across India is more than just a festival; it’s a time for family reunions, community bonding, and reverence for tradition. People celebrate it with the warmth of togetherness, serving as a reminder of the resilience and enduring beauty of India's diverse cultural heritage.
