A Diwali kandil, also known as a Diwali lantern, is a decorative symbol synonymous with the festival of lights, Diwali. These lanterns play a significant role in illuminating homes and streets during the festive season, signifying the triumph of light over darkness and good over evil. The tradition of hanging kandils stems from the desire to welcome prosperity and happiness into one's home, as they are believed to ward off negative energies.
