Diyas are small oil lamps traditionally made from clay. They are commonly used in Indian culture, especially during festivals like Diwali, to symbolize the victory of light over darkness. Diyas are filled with oil and have a cotton wick that is lit to produce a warm glow. These lamps are often decorated and placed around homes, temples, and public spaces to create a festive atmosphere. In addition to their decorative purpose, Diyas also hold spiritual significance, representing purity and the dispelling of ignorance. They are an integral part of various rituals and celebrations in many cultures.
