Diwali is known as the festival of lights.
Diwali (also spelled Devali in certain regions) or Deepavali, popularly known as the "festival of lights", is an important five-day festival in Hinduism, Jainism, and Sikhism, occurring between mid-October and mid-November. For Hindus, Diwali is the most important festival of the year and is celebrated in families by performing traditional activities together in their homes. Deepavali is an official holiday in India, Nepal, Sri Lanka, Myanmar, Mauritius, Guyana, Trinidad & Tobago, Suriname, Malaysia, Singapore, and Fiji. http://en.wikipedia.org/wiki/Diwalihttp://en.wikipedia.org/wiki/DiwaliChildren in our village make Narkasurs (monsters or evil creatures). They burn it on Diwali. Burning Narkasurs symbolises the destruction of evil.
In the village where I stay (Saligao), every Hindu house is lit up so beautifully. They hang akash divos (lanterns) and they also keep pontis (small clay lamps) and put rangoli designs all over the floor. Rangoli is a particular type of colour, which is used to decorate floors and make designs.
