Shiva is worshiped as Annamalaiyar or Arunachaleswarar, and is represented by the lingam, with his idol referred to as Agni lingam. His consort Parvati is depicted as Unnamalai Amman. The Karthigai Deepam festival is celebrated during the day of the full moon between November and December, and a huge beacon is lit atop the hill. It can be seen from miles around and symbolizes the Shiva lingam of fire joining the sky. The event is witnessed by three million pilgrims. On the day preceding each full moon, pilgrims circumnavigate the temple base and the Annamalai hills in worship called Girivalam, a practice carried out by one million pilgrims yearly.
