About Kootruva Nayanar
This saint was a chieftain of Kalandai. He was extremely devoted to Lord Siva. Daily he would repeat the Panchakshara Mantra, and serve the Bhaktas. The Lord made him more powerful, and bestowed on him all wealth and strength. Nayanar captured many places in the Chola and Pandyan kingdoms. He wanted that the three thousand Brahmins of Tillai should crown him king: they refused, because they owed allegiance to the Chola king. All of them even left Tillai fearing his wrath. Only one was left to do the Puja. Even he refused to accede to Nayanar’s request. One day Nayanar prayed to the Lord: and, in answer, the Lord Himself appeared before him and crowned him by placing His Feet on his head. Nayanar continued to worship the Lord and finally attained Him.
The Lord, the Indweller of our hearts knew that, when the Nayanar asked the three thousand Brahmins to crown him, it was only to spiritualise the coronation and to enable him to feel that the crown was but a symbol of the Feet of the Lord. When the Brahmins feared political repercussions, the Lord Himself fulfilled the devotee’s wish.
