Post colonial writers attempted to portray the social and political milieu in their works. They depict the nonconventional themes which have broken the pre-occupied age- old tradition established by the writers since Vedic period. Writers started writing on East-West encounter, urban middle class mores, changing patterns of human relationships and slowly their concerns widened. The post- independent era hoists the flag of women’s writings with the flavor of real incidents of their life which were often hidden from others. They become the voice of society through the medium of literature. Their accents are loud enough to be heard in the field of Indian English writings as voices of women who could write of experiences of living confined lives. Jhumpa Lahiri herself being an Indian-American, born to Bengali immigrant parents, is able to fictionalize the live and real experiences of immigrant Indians in America. As an eye-witness ‘Bengali-American’ writer of Indian ancestry, Lahiri is crowned as an International writer among the Commonwealth Writers and has a universal appeal. She explores her character’s dilemma, struggles, anxieties and biases to express details of immigrant psychology and behavior. Her characters swing between their native culture and the culture of the host country resulting in their cultural hybridist. The first and second generations play the role of cultural mediators between the adopted culture and the culture of motherland. This paper explores Lahiri’s depiction of Bengali culture in The Namesake ranging from the food habits, dress, festivals, rituals, customs, religious ceremonies, music as well as the behavior of the first generation immigrants in America who eagerly strive to transmit them to the second generation individuals.
