From google books: The establishment of new nation-states after the partition of British India in 1947 not only required new geographical boundaries but also a cognitive map with mental borders that inform who are included and excluded. This book concerns the 'tyrannical' workings of such borders on the mind of nation-builders in both Bangladesh and India. In the end, the author argues that if the continuation of the two nation-states circumscribed by geographical borders is desired, their cognitive maps have to be altered through new mental borders that de-partition these societies.
