This chapter offers an analysis of ethnographic texts on the Buen Vivir and indigenous well-being in Mexico, highlighting that the concept is not unique but a plurality of meanings linked to diverse sociocultural realities. The research emphasizes the intrinsic connection of indigenous well-being with the relations between society and nature, as well as with the social fabric of the community, differentiating it from purely economic or material development visions. Finally, it discusses how these visions of the Buen Vivir can shed light on the so-called “happiness paradox in Latin America”, where subjective well-being seems disconnected from difficult objective living conditions.
