Sehnsucht (Life Longings) is a profound phenomenon manifesting as an intense sensation often linked with idealised views of life’s missing aspects. This chapter explores its psychological, emotional, and cognitive dimensions, cultural implications, and role in personal development. It also examines the euro-scientific basis and related emotional processes. This chapter also includes a detailed case study of a 60-year-old German woman who utilised artistic expression to navigate her existential crisis following a divorce. Through the creation of a visual-text collage, Flora’s engagement with Sehnsucht led to significant personal transformation, rediscovery of resources, and enhancement of her well-being and resilience. This comprehensive methodology aims to provide a holistic understanding of Sehnsucht as a complex and profound emotion, integrating insights from positive psychology, neuroscience, and cultural studies.
