This paper explores the profound internal conflict between the mind (intellect) and the heart (emotion) caused by love, as mirrored in the celebrated Mizo poet Lallianmawia’s song “Fur Khawthiang Eng” (composed in 1985). Despite his subsequent marriage and passing years since his separation from his former wife, Rinpuii, the song reveals an irrepressible emotional turmoil and unyielding longing. To analyse this psychological conflict, the study employs psychological and literary frameworks, including Sigmund Freud’s concepts in “Mourning and Melancholia,” Thomas Lewis et al.’s A General Theory of Love, Denis de Rougemont’s Love in the Western World, and K. Hminga’s song “Rilru Indona.” Furthermore, T. S. Eliot’s concept of the “dissociation of sensibility” is utilized to elucidate how the human mind (which seeks to forget) and the heart (which continues to love) can become structurally divided and locked in perpetual warfare. Ultimately, the paper demonstrates how Lallianmawia’s work serves as a poignant testament to the persistence of emotional memory and attachment within human consciousness despite physical separation.
