The Story of Pulavar Poyyamozhi

A poet in South India by name Poyyamozhi Pulavar or Siva Kavi had intense devotion for Lord Siva, and refused to sing the glory of Lord Shanmukha, stating he would sing on cock (Siva), not on chicken (Murugan). 'சேவலை பாடும் வாயால் கோழிக்குஞ்சை நான் பாடுவேனோ '

The Lord wanted to protect him and so took the form of a hunter and chased the poet. When the latter pleaded for relief, the hunter asked him to sing on him. The poet asked for his name. The hunter said it was 'egg' (muttai). To save himself from the fierce hunter, Poyyamozhi sang in praise of muttai. Immediately the hunter asked him why he sang on egg when he did not even want to sing on the chicken. The poet realized that the hunter was Murugan himself and he repented for his pride and ignorance. http://rightmantra.com/?p=27746
