Ripples Alliance weaves psychedelics, peacebuilding, science, art, and rituals to foster a movement of peace and liberation – in Palestine and Israel, and beyond. It is the continuation of seven years of research. Working with a cohort of Palestinian and Israeli researchers, peacemakers, and artists, several successful sessions resulted in deep personal & collective healing and visionary future building. Three groups of Palestinians and Israelis were invited to participate in an Ayahuasca peacebuilding program. The invitation was to explore the ceremonial and healing space of ayahuasca through a collective intention: In this lecture-performance, Leor will weave political realities with liberatory imaginaries by sharing results, stories, revelations, revolutions, reflections, and updates from Ripples Alliance.
