Indian English Literature has struggled hard to prove its existence & worth and it has now achieved worldwide recognition. As India had been under the British rule for about nine hundred years, the Indian writers even after achieving the Indian Independence could not altogether shake off the memories and the influences of the colonial past. However, the Indian writers tried to ignore the foreign impact and had written in more in tune with the age and its general temper, and to naturalize in the Indian soil the modernistic elements derived. In a word, Indian English Literature / Indian Writing in English has achieved a lot during the last sixty years, but we should not forget “the undone vast”. The Literature of the Indian Diaspora is no longer an expression. The diasporic movement and the insider-outsider approach of the migrant beyond national borders are now given and became something usual. The multiple locations as it happened with the writer like Salman Rushdie characterize the collective mobilization around the tension between home and abroad and they are now defined around challenges to a notion of settlement and fixity. And this questioning of singular location becomes a foil for various conceptualizations such as diasporic consciousness, and de-territorialization. The significance of diaspora and its productions as an area-study emerged alongside the intellectual movements in the academy such as post-colonial studies and the ubiquitous process for globalization. Diasporas, and the diasporic imagination are at work in going back a step towards the past memories and retreat. As a parallel pre-occupation, sometimes nagging, several contemporary writers and writers of Indian origin experience a marked and a different memory of the homeland and a different kind of accommodation in the new place. Keywords: de-territorialization, collective mobilization, nagging, area-study, diasporic consciousness.
