A clay diya is a traditional Indian oil lamp made from clay, commonly used during festivals and religious ceremonies. The diya typically consists of a small, shallow, bowl-like structure with a spout for holding oil and a cotton wick. It is filled with oil, often ghee or vegetable oil, and the wick is lit to produce a warm and flickering flame. Clay diyas are not only functional but also hold cultural and spiritual significance, symbolizing the triumph of light over darkness. They are often decorated with intricate patterns, colors, and sometimes adorned with additional embellishments. The use of clay in making diyas highlights their eco-friendly nature, as they are biodegradable and contribute to a sustainable celebration.
