Karthigai Deepam is a festival of lights that is celebrated in the southern state of Tamil Nadu, India. It falls on the full moon day of the Tamil month of Karthigai, which usually falls in November or December. One of the unique and significant features of this festival is the use of brass lamps or “Kuthu Vilakku” to illuminate homes and public spaces. Brass lamps have been an integral part of Indian culture and tradition for centuries. They are considered sacred and are used during religious ceremonies, festivals, and other auspicious occasions. Brass lamps used during Karthigai Deepam are usually made of high-quality brass and come in different sizes, shapes, and designs. The preparation for the festival starts several weeks in advance. People clean and decorate their homes with colorful rangolis and flowers. They also purchase or make their own brass lamps, which are then filled with oil and a cotton wick. On the day of the festival, the lamps are lit at dawn and are kept burning throughout the day. In the evening, the entire town or village is illuminated with a sea of twinkling lights from the brass lamps. It is a breathtaking sight to behold, and it creates a festive atmosphere. The lamps are placed in front of homes, on balconies, on rooftops, and in public spaces like parks and temples. People offer prayers and perform aarti (a Hindu ritual of worship) in front of the lamps. The lighting of the brass lamps during Karthigai Deepam has a significant spiritual meaning. It symbolizes the victory of good over evil and the triumph of light over darkness. It is believed that the light from the lamps dispels negativity and brings prosperity, peace, and happiness to homes and communities. In some parts of Tamil Nadu, a special lamp called “Mahadeepam” is lit on the top of a hill called Arunachala in the town of Tiruvannamalai. The lighting of this lamp is a grand spectacle and is witnessed by thousands of people who come from far and wide to witness it. In conclusion, brass lamps play a significant role in the celebration of Karthigai Deepam in Tamil Nadu. They add a unique charm and warmth to the festival and bring people together in a spirit of harmony and joy.
