Mahatma's contribution to promotion of communal harmony is most significant in modern India. This contribution is neither merely academic nor only as political activist but much more than that he laid down his life for his cause. Also, the Mahatma wrote and spoke profusely on this problem. We can hardly think of any individual in modern India who wrote and spoke on this problem as much as the Mahatma did. His writings and speeches on this problem run into hundreds of pages. Mahatma wrote and spoke on this problem from all possible angles.
