Diwali or Dīpāvali[1] (Sanskrit: दीपावलि: a row of lamps[2]) is a significant festival in Hinduism, Buddhism, Sikhism, and Jainism, and an official holiday in India.[3] Adherents of these religions celebrate Diwali as the Festival of Lights. They light diyas—cotton string wicks inserted in small clay pots filled with oil—to signify victory of good over the evil within an individual.
