Diwali festival

Today is Deepawali or Deewali. It is a festival of lights. It can be considered as the most pious and important festival of Hindus [this is fine, but maybe better: "It is considered the most pious..."]. It is said that on this day Lord Rama, after defeating Raavn, came back to his hometown Ayodhya. Therefore, people lit up their houses to welcome Rama. Since then, each year, Deewali is celebrated. We light up candles and diyas [I don't know what a diya is...] in our houses, and worship Lord Rama and the goddess Laksmi. Further fireworks are used by children.

[Happy Diwali!!!]
