A colorful festival that is celebrated by all Hindus worldwide is Deepavali, which is also known as the festival of lights. This festival usually falls around late October and November. One important practice that the Hindus follow during the festival is to light oil lamps in their homes on Deepavali morning. By lighting the oil lamps, the Hindus are thanking the gods for the happiness, knowledge, peace and wealth that they have received. The Hindus consider Deepavali as one of the most important festivals to celebrate. As a hindu who celebrates this festival, i think it is equally important for others to know a little bit of this festival as this is a multiracial country.
