It is said that his songs are the outcome of five centuries of Bengali literary churning and communal yearning. Dhan Gopal Mukerji has said that these songs transcend the mundane to the aesthetic and express all ranges and categories of human emotion. The poet gave voice to all—big or small, rich or poor.
