Kanampulla Nayanar was a wealthy man in Irukkuvelur. He was a great Siva Bhakta. He wanted to utilise all his wealth in His service only. So, with unswerving devotion he would light the lamps in Siva shrines and sing His praise. Lord Siva wanted to reveal his devotion. He withdrew his wealth. He went over to Chidambaran. There also he continued his service, with the money got by selling his possessions. There was nothing left in the house. He had to cut grass, sell it and purchase ghee with the money and burn the lamps. Because he cut grass known as Kanampul, he was known as Kanampulla Nayanar. One day he could not sell the grass. He did not want to swerve from his duty, however. He went to the temple and made a wick out of the grass and burnt it. The quantity of grass was not enough. So, he brought his own head near the lamp, spread his hair on the lamp, and began burning it. At once Lord Siva appeared before him, and blessed him.
