Diwali Diyas are small oil lamps traditionally used during the festival of Diwali, also known as the Festival of Lights. Made from clay, these diyas are filled with oil and have a cotton wick that is lit to symbolize the victory of light over darkness and good over evil. Families place them around their homes, creating a warm and inviting atmosphere. During Diwali, people often decorate their homes with colorful rangoli and hang beautiful lights, but the diyas hold a special significance. Lighting these diyas is a way to invite prosperity and happiness into one's life, making them an essential part of the celebrations.
