History – When Dakshan conducted a yagnya without inviting his son-in-law [Lord Siva], Lord Siva forbade his wife Dakshayini to attend the event.
She argued that it was conducted by her father and that she would go and make him realise his mistake. However, she was ill treated at the function and she self immolated. When Lord Siva heard about this incident, he was furious and started dancing.
Every time he hit the ground with his matted locks, one new Rudra emerged. Thereby 11 Rudras came to be. All Devas and Rishis were scared and went to Perumal to help pacify Lord Siva.
Perumal appeared before each of the 11 Rudras and thereby we have 11 Divya Desams in this place. All these 11 Perumals are said to have come from the North to give darshan to Rudra.
