Grâce
Perur is sacred not only because it is one of the 'sivasthalams' of Kongunadu, but also because the Divine grace of Lord Siva is so immanent and perceptible that when Sundaramoorthy Nayanar, one of the four preceptors of Saivism, went to chidambaram to worship Lord Nataraja, he found there but the deity of Perur. He stays in this Thillaikkoil hymn. Hence it is no wonder that our St.Santhalinga Swamigal was also attracted by this holy city.
