What is Diwali, the festival of lights? What religions celebrate it?
According to National Geographic Kids, Diwali, or Deepavali, is known as the festival of lights. Over time, it has become a national holiday. Communities in Hinduism, Jainism and Sikhism have their own way of celebrating it.
The word Diwali is derived from the Sanskrit word Deepavali, meaning “row of lights.” This refers to the row (avali) of clay lamps (deepa) that observers light outside their homes during Diwali to represent the light that guards against spiritual darkness.
How is Diwali observed?
Depending on the region and tradition, observances of Diwali differ, according to Britannica.
The most common practice among Hindus is to light diyas (small clay lamps filled with oil) on the night of the new moon to summon the goddess of prosperity, Lakshmi.
When the diyas are lit, they are placed in rows in temples and houses or set afloat on rivers and streams. Homes are traditionally decorated with rangoli, deliberate designs made with colored rice, sand, or flower petals to summon the goddess Lakshmi to bless their home with wealth and success.
