This in an extract from Navakoti Narayana, an old kannada movie on the life story of Shri Dasashreshta Purandara Dasa.
Shri Purandara Dasa is one of the greatest stalwarts of Karnatic music. He laid the foundations for teaching Karantic music with a simplified method. Today it is this method used to teach karnatic music to anyone and everyone in india. It is his compositions that are taught first to train students in music.
As the saying goes,"ದಾಸರೆಂದರೆ ಪುರಂದರ ದಾಸರಯ್ಯ", he was also one of the greatest proponent of bhakthi movement of his era.
