Jasmine,one of the most oft-discussed migration works by Indian-American writer Bharati Mukherjee,expresses the theme of transnational identity across the United States and India.With the critical theories of identity studies,Jasmine is interpreted along the research path involving statements that"home"is not"home","leaving home"is not"home",and there is nowhere to be"home".This work there by reveals three deeper textual metaphors:Indian imagination,alienation and empowerment of people in liminal space,and nomadic desire and solution,so as to demonstrate how the protagonist's multi-dimensional identity is formed.With"home outside the boundary"in response to the research question"What is'home'",Mukherjee shows her literary imagination of the disappearance of rigid boundaries in real society,reflecting the construction of her postmodern political identity.
