An old Tamil song

I remember my mother singing this around 1947-48, she even had the lyrics written in Telugu script in her song book (a book which I inherited and lost). She learnt it from the daughters of Tamilian teacher in Gudavalli who lived near us. The tune and a few Tamil words is all I remembered. Apparently, it is well known as I found in this wonderful blog yesterday: the song from 5:36 onwards
