Amitav Ghosh’s fictional works tend to problematise the sense of belongingness for the generations of the South Asian diasporic population who face the trauma of displacement. The notion of home is altered for the diasporic population when the primary memorialisation of the lost home fades away and the ‘homing desire’ is gone. The diasporic characters in Ghosh’s novels majorly resist spatial trauma as they try to forge new identities in the host land, and subsequently, a change in their belongingness can be observed. Through the readings of The Shadow Lines (1988), The Glass Palace (2000), and The Hungry Tide (2004), this paper examines how the diasporic population in Ghosh’s novels construct a homely space in their host land after resisting the spatial trauma and how the memory of the lost home affects their sense of belonging. Borrowing Heideggerian notions of ‘place’ and ‘space’, this paper brings to the fore how such apparently interchangeable terms can influence the sense of belonging of the diasporic population. While theorising African consciousness, Paul Gilroy has paid equal importance to the notion of ‘roots’ and ‘routes’, and this paper argues that roots are diluted due to the traumatic memories and new routes are taken to construct an altered home. The characters in these three novels travel extensively, leave their homeland, negotiate the alterities in the host land, memorialise their lost space and create their new place which they might or might not call home.
