Nandikeshwarar is the vahana (vehicle) of Lord Shiva and can be seen in all Shiva temples sitting in front of the Lord and seeing him. His significance is such that ‘abhishekam’ is performed on him on every ’Pradosham’ – an auspicious day that falls twice in a month. People gather in large number on this day between 4:30 and 6 in the evening to witness this event.
