This two-volume handbook reimagines the role of emotions, offering transformative insights into their significance for individuals, communities, and societies. Volume 1 combines rigorous theoretical exploration, personal narratives, and cutting-edge research to explore the intricate connections between emotions, human development, and positive psychology. Far beyond the confines of emotional well-being, this volume examines the transformative power of emotions in shaping identities and driving personal and collective growth. Through its comprehensive approach, it paints a vivid picture of the human emotional experience while navigating diverse cultural contexts and intergenerational dynamics. This work challenges conventional approaches by integrating perspectives from various cultural backgrounds and cross-cultural experiences, offering readers a deeper understanding of how emotions influence relationships, decision-making, and societal change. It is an indispensable resource for psychologists, researchers, educators, and practitioners aiming to expand their knowledge of emotions in a global context and apply innovative frameworks in their work. Through its synthesis of theory and practice, the handbook invites readers to rethink the emotional dimensions of human experience. It encourages the exploration of new paradigms that highlight the transformative potential of emotions and their ability to shape inclusive and emotionally intelligent communities. This volume is more than a collection of knowledge—it is a call to action for those who seek to understand and harness the transformative potential of emotions. Whether exploring the role of emotions in culturally diverse and transcultural understanding or their impact on personal growth, this handbook opens new pathways for academic inquiry and practical application, redefining how we perceive and engage with the emotional fabric of our world.     Emotion science has progressed enormously in the last decade.
