Made from clay, metal, or glass, it is filled with oil and has a cotton wick that is lit to produce light. Diyas symbolize the victory of light over darkness and are often placed in homes and temples to create a warm, inviting atmosphere. These lamps are not only functional but also hold cultural significance. They are often decorated with colorful designs and can be found in various sizes. Lighting a Diya is a cherished ritual that brings families together and enhances the festive spirit.
