Book excerpt: EDITORS' INTRODUCTION BACKGROUND There have been major changes in world today and that the term Global Leadership and Sustainable Development is no longer taken for granted as a point of reference for understanding the contemporary chaotic situation. These disruptive changes mean that it is now arguable as to whether we still live in a world of justice, egality, peace and prosperity. The nature of these changes and the concepts of the Buddhist approach are central to the whole project of this book. In this light, we place great emphasis on understanding Buddhist teaching in dealing with this matter. We argue that any investigation of the changing character and context of the present time, needs to take account of the Buddhist philosophy. We focus on providing a thorough and critical understanding of change taking place as a starting point of discussion. In doing so, we attempt to clarify the nature of the Buddhist approach. It may be more productively understood as the result of a complex contested and fragile set of arrangements, which in this book we term as “approach”. We do not imply that the frameworks based on the Buddhist teachings are fully fixed and agreed by everybody. Rather it would refer to a set of arrangements that need to be further discussed. Given the above, this volume collects together papers presented at the international workshop on Buddhist Approach to Harmonious Families, Healthcare and Sustainable Societies which took place on 13 May 2019 at International Conference Center Tam Chuc, Ha Nam, Vietnam on the occasion of THE 16TH UNITED NATIONS DAY OF VESAK CELEBRATIONS 2019. The participants in this workshop were not representative of the mainstream thinking or conventional wisdom of this field, although this volume reflects this richness and diversity. Treating the Buddha teachings as a basic theoretical reconstruction, we examine the relationships between the societies and Buddhist responsibilities. We combine analyses of the conflicts, trends and dynamics affecting future development with more focused studies on a range of policy areas: migration, education, leadership, climate change, etc… Two of our most crucial presumptions are that making Buddhism great again at the time of disruption is our first and foremost duty and the Buddhist responsibility can contribute to creating a new foundation for Global Leadership and Sustainable Development.
