" Building on over a century of interfaith engagement, Volume 1 traces the evolution of this movement from 1999 to 2015, illuminating how people from diverse backgrounds are bridging traditions and rediscovering the sacred through one another. With newly written articles, selected excerpts, abridgements, essays, and historical reflections, The Heritage captures the formative years of Interspirituality. The volume includes foundational benchmarks such as the Snowmass Dialogues, the Monastic Interreligious Dialogue, the Interspiritual Dialogue, Spiritual Paths, One Spirit and Satyana networks, the New Monasticism, and many more initiatives, organizations, and events. Framing the volume are H. H. the 14th Dalai Lama and Matthew Fox, alongside a diverse array of mystics, activists, educators, and spiritual leaders committed to building a "world that works for all. " Contributors speak to the spiritual dimensions of partnership consciousness, peace, justice, economic equity, sacred activism, ecological healing, and our evolutionary future.
