Line is the forte of Nabakishore's paintings. They swirl, surge, intertwine, even retreat and move diagrammatically convering the pictorial space. Nabakishore lets his pen or brush move on the paper freely. The figures born out of those lines and of the exuberant colour splashes have a naive charm about them. They show faces of a next-door girl or of a folk deity and recall the images that we see in folk art of rural Bengal. In his paintings, symboils including the phallic ones create a primordial ambience. His browns and yellows, red and greens trapped in the darkness make up a rich fabric of forms.
Nabakishore is a self taught painter who teaches Bengali language and literature in a college. his knowledge of medieval Bengali poetry is simply reflected in the images that he paints. As a painter, he recreates the world of mythology and folklore in a visual language that seems unique.
