Emotion repertoires, as part of cultural repertoires, enable individuals and collectives to relate to one another on the discursive, practical, and embodied levels at which emotions and affects evolve. They are formed during processes of socialization but remain flexible due to subjective experiences, societal transformations, and life-long formations of feeling. The chapter highlights the analytic interplay of three dimensions – durability, practicability, relationality – as constitutive of emotion repertoires. With empirical data from anthropological-psychiatric research in Vietnamese lifeworlds in Berlin, we pay particular attention to the affective efforts involved in therapeutic processes, in which more flexible understandings of competing or conflicting emotion repertoires are negotiated.
