I will endeavor in this research to explore the theme of Indian postcolonial diaspora, cultural dislocation and the resulting alienation. The article attempts to trace the multiple terrains of cultural and psychological struggle within the expatriate, the nostalgia that accompanies the expatriate experience and the ongoing conflict between the past and the present. I also intend to analyze the series of crises that migrants experience in order to seek acceptance in new cultural faiths. The nature of this postcolonial study aims to explore the conflicts between Indian traditions and Western habits. To support my arguments, I chose the famous novel The Namesake written by diaspora writer Jhumpa Lahiri. Define diaspora. The word diaspora is important and relevant to all those who have migrated to various countries around the world in search of better fortunes. The word diaspora literally means “to disperse.” He is of Greek origin. In the book “Key Concepts of Postcolonial Studies,” Bill Ashcroft, Gareth Griffiths, and Helen Tiffin define diaspora as the “voluntary or forced movement of people from their original lands to new regions…” (Ashcroft 68). In the words of Robert Cohen, diasporas constitute a community that lives together in foreign lands to “recognize that the old country – a nation often buried deep in language, religion, custom or folklore – still has rights in terms of loyalty and emotions. (Cohenix). In Jhumpa Lahiri's novel The Namesake, we find the first-generation migrant protagonist, Ashima Ganguly, who looks to the past and tries to find solace in recreating her homeland which was Calcutta in the new foreign territory of Cambridge and New York. In this context, I find this relevant to middle of paper......only for a single culture, ethnicity or nationality. In other words, second generation immigrants like Gogol, Sonia, Moushumi are the product of hybrid cultures. In the era of globalization, with changes in location, expatriates are integrating new ethnicities which are giving birth to a whole new cultural identity. The story philosophically explores the spatial dislocation, cultural alienation and emotional isolation of expatriates. The journey in search of identity is always difficult, even more so in the expatriation experience. The land of opportunity simultaneously becomes the land of crises and confusion. Psychologically, the expatriate slowly imbibes the hybrid cultural denominations and continues to evolve into new dimensions while consciously accepting the historical past as the point of origin of his spiritual and emotional soul identification..
