This article engages with the post-1992 (Rio Earth Summit) writings of Leonardo Boff, one of the most prolific and widely read Brazilian writers in the religious field today. The article first outlines Boff's understanding of the prevailing global market paradigm, guided by 'liberal capitalist' values and at the point of crisis. Boff's appreciation of the emergent 'new science' paradigm as providing conceptual impetus to fresh understandings of relations between the sacred, the self, and the universe is then delineated. The understanding of mystical experience as universal connectedness, informed by the 'new science' paradigm and emerging from Boff's 'trans-cultural phenomenological' reading of religious discourse and practice, is subsequently explored in depth.
