This chapter examines the intergenerational transmission of trauma and shame in South Asian contexts, foregrounding the role of the conspiracy of silence, cultural norms, and trauma-informed theological frameworks in shaping psychological and relational patterns. The chapter also introduces four culturally specific attachment types: inherited-loss, shame-bonded, survivalist, and transcendent, situating them in dialogue with Bowlby’s attachment theory to highlight parallels, divergences, and the influence of historical, familial, and socio-cultural forces. The chapter then introduces the South Asian ecological systems theory, mapping how trauma and shame are transmitted across individual, family, community, and societal layers before exploring the clinical and social implications, illustrating how multigenerational dynamics, family structures, and cultural narratives mediate experiences of trauma, identity, and resilience, while offering insights into culturally attuned approaches for understanding and addressing psychological distress in South Asian diasporic populations.
