“Never lose your bold brushstrokes, this gesture is unique to you,” one of his Parisian art professors would always tell him. Having ingrained all the Western art movements, Sen worked towards finding his own direction in art. He invented a new ideology he called Gesturism Art, a style that uses his bold brushstrokes. In Gesturism Art he incorporates his philosophical angle of human life which has a multitude of gestures from birth to death.
When India was partitioned 1947 to create Pakistan, a new country for Muslims, about 20 million people of Bengal and Punjab were displaced and brutally victimized. Sen’s wealthy, literate family had huge landed property in erstwhile East Bengal, the present Bangladesh, which was carved out to be East Pakistan for Muslims. So for being Hindus Sen’s family was overnight evicted from their home. Without taking any possessions, they fled for their lives amidst people warring over religion, and so became squatted refugees in West Bengal.
