This song is set in the Thiru ezhu kootrirukkai pattern which falls under the Chithrakavi way of writing poems. words strung in such a way that an image is formed. it is said singing this or listening to this one thiruppugazh is equivalent to singing all 16000 thiruppugazh!
i am so fortunate I decided to take this up, a song I learnt more than 15 years ago.
