Karthigai Deepam is a Tamil festival associated with the Tiruvannamalai Mahadeepam, where lamps are lit in homes and temples to commemorate the appearance of Lord Shiva in the form of a torch to Brahma and Tirumal. In Ambattur, people also celebrate this divine festival of light by lighting lamps, decorating homes, and worshipping in temples. In Ambattur areas, on Deepam day, special pujas, lighting of lamps, and celebrations with family are held in local temples and homes.
