Diwali, the spectacular Hindu festival of lights celebrated all over the world, is under way.

The five-day event began on Tuesday with traditional holiday staples like candles and oil lamps called "diyas" lit to celebrate the return of Hindu god Rama to his kingdom after years of exile. Diwali, a contraction of the word "Deepavali" -- meaning row of lights in Sanskrit -- is often celebrated with food, dancing, parties and, of course, colorful lights hanging everywhere.

Diwali is not only celebrated in India but in many non-Indian nations like Trinidad and Tobago, which have large Hindu populations, CNN reported. Each nation celebrates the holiday differently, though the elements remain the same.

In New Delhi, the capital of India, residents decorated their homes with "rangolis," flowers, lights and earthen "diyas" for the occasion, according to NDTV.com. In Amritsar, thousands flocked to the Golden Temple to pay obeisance. In Tamil Nadu, newlyweds celebrated their first Diwali tougher by saying "Thalai Deppavali" to their new spouse.

Roger Seepersad, who is from Trinidad and Tobago, told CNN "the Hindu community celebrates by cleaning their houses and preparing foods such as roti, channa and aloo, white rice, and various vegetable curries. They also prepare sweets like parsad, kurma and barfi. At around 6 p.m., they light deyas around their houses. Hindus invite friends and family over to help with the diya lighting and to just enjoy each other's company ... At night there is usually tons of fireworks as well."
