Sikhs actually celebrate a separate holiday, Bandi Chhorh Divas, which happens to coincide with Diwali and, since it commemorates the anniversary of the Sikh Guru Hargobind Sahib being freed from prison in the 1600s, shares some of its themes.
During this time, Lord Ram and his brother Lord Laxman fought a fierce battle with the demon King, Ravana of Lanka, who had kidnapped Sita.
The battle ended with Ravana being killed by Lord Ram and is seen as a victory of good over evil.Meanwhile, Buddhists recall Diwali as the day that the Indian Emperor Ashoka converted to Buddhism.Not only does this international holiday come with regional customs ingrained in its wider traditions, it varies in length (from five days to 12) and even name (it's known as Galungan in Indonesia and Tihar in Nepal, for example).Here is a brief write-up on Diwali that can be used as a reference point by school, or college students. Deepavali in Sanskrit, or Diwali, the more popular name today, is perhaps the most celebrated Hindu festival in India and stands out as a festival of sparkling lights, fun and joy, a time for creative Rangoli decorating each home, and a time for some of the finest delicacies and puja offerings.It is a day when everyone puts on new and colourful clothes, that only adds to the charm and spirit of the festival.This festival "is marked with new beginnings, joy, celebration and remembrance of the connection between humanity and divinity," Trivedi says.Writing an essay on Diwali can be tricky, but it is by no means impossible.This is a day when people buy some form of jewellery, be it gold or silver, as it marks the auspicious beginning for the coming new year, as per the Hindu Vikram Samvat.Buying of steel utensils is also seen as auspicious.Over time, there have been different interpretations of various legends and beliefs and today, we see that in different parts of India, the same festival is celebrated with pomp and gusto but with varied interpretation of its origins.Mostly, Diwali is celebrated as a five-day festival, with each region celebrating the festival in their own unique way.
