Diwali, or Deepavali, is the Hindu festival of lights. It is celebrated in a big way in India and Nepal, where it is called Tihar. The term Deepavali is of Sanskrit origin, which means an array of lamps. The word ‘deep' means clay lamp and ‘avali' means an array. The celebration of the festival signifies the victory of good over evil within oneself. The word Diwali is actually a corruption of the Sanskrit term Deepavali. Today it is celebrated by Sikhs, Jains, Hindus, and even some Buddhists all around the globe.

The festival has a deep significance since ancient times. According to the Vedic culture, the message of Diwali is to eradicate the world from darkness and lead it towards the self-illuminated light within. Here, each individual is likened to a brightly lit clay lamp. The message is to collectively participate in the endeavour, as it is not just the effort of one individual. The differences between the high and low are forgotten, as the aim is to usher in equanimity and equality in society.

Traditionally, the celebration of Deepavali is associated with a number of mythological events. In Northern India, Deepavali is celebrated to celebrate the return of King Rama to his Kingdom Ayodhaya after from a 14 year exile and victory over the demon king Ravana. The people of Ayodhaya lit an array of clay lamps to celebrate his return.

In Southern India, another legend describes the victory of Lord Krishna over the demon Narakasura. In western India, it is celebrated in the honour of the King Bali who went to rule the nether world by the order of Lord Vishnu.

The festival has varied significance all over India. In West Bengal, it is celebrated in honour of Goddess Durga. Particularly, in the north of India, Hindu merchants open their new books and pray to Goddess Laxmi for a joyful and prosperous new year.
