Why Diwali is Celebrated? The Core Meaning

Diwali symbolises the victory of light over darkness, good over evil, and knowledge over ignorance. The festival, known as “Deepavali,” means a row of lamps and falls on the new moon (Amavasya) of the Hindu month of Kartik (Ashwin in the Purnimanta calendar), usually in October-November.

The festival evolved from an autumn harvest and new-year festival into a pan-Indian celebration. Diwali is observed by Hindus, Jains, Sikhs and some Buddhist communities, each with its own significance.

Diwali celebrations can vary widely from one community to another, showcasing the festival's cultural richness. For example, in North India, the festivities are primarily linked to Lord Rama’s return, while in West India, the focus often shifts to worshipping Goddess Lakshmi. In South India, the celebrations highlight Krishna's victory, and in East India, they may coincide with the veneration of Goddess Kali.

These variations create a vibrant tapestry of customs, rituals and festivities. Each community adds its unique flavour to Diwali, from the types of sweets prepared to the specific prayers offered. The joy and togetherness experienced during Diwali resonate across cultures, making it a truly national festival.

How to Celebrate Eco Friendly Diwali

Celebrating Diwali can harmoniously blend joy and environmental mindfulness. Here are some straightforward yet impactful ways to ensure your festivities are more sustainable:

• Use Natural Decorations: Ditch the plastic and opt for decorations crafted from natural materials. Dried flowers, clay diyas, and biodegradable rangoli colours add charm without harming Mother Earth.
• Choose Eco-Friendly Diyas: Replace chemical-laden electric lights with traditional clay diyas. You can even make your own using local clay and decorate them with organic paints for a personal touch.
• Limit Fireworks: Fireworks lead to significant air and noise pollution. Consider reducing their use or selecting eco-friendly alternatives that produce less smoke and sound.
• Sustainable Gifting: When it’s time to exchange gifts, think about eco-friendly options. Handmade items, potted plants or experiential gifts can be thoughtful and sustainable alternatives to plastic toys and electronics.
• Reduce Waste: Plan your meals wisely to avoid excess food waste. Using reusable plates and cutlery instead of disposables can significantly minimise trash. Invite friends and family to bring their favourite dishes for a communal feast, allowing everyone to savour different flavours while easing the cooking burden.
• Community Clean-Up: After the celebrations, consider organising or joining a community clean-up. It not only benefits the environment but also strengthens community bonds. Organise a charity drive to collect food, clothes, or toys for those in need. This reflects the core values of sharing and generosity that Diwali embodies.
