Diwali (also: Deepawali) is one of India's biggest festivals. The word 'Deepawali' means rows of lighted lamps. It is a festival of lights and Hindus celebrate it with joy. During this festival, people light up their houses and shops with Diyas (small cup-shaped oil lamp made of baked clay). They worship the Lord Ganesha for welfare and prosperity and Goddess Lakshmi for wealth and wisdom.
