Sri Annamalaiar Hill is considered as Lord Shiva's great presence in Thiruvannamalai. People believe that the huge light lit during 5 pm will make people close with Lord Shiva on Kathigai Deepam. Lord Shiva will shed all his blessings during this special time of the year. He is rigidly worshipped during this time. Great care is taken to light the huge fire in this place. People gather around the place and call in the name of Shiva to put an end to all the troubles and bring in peace in every life.
