This volume, presented to John R. Hinnells on his 75th Birthday, focuses on the interface between material and spiritual wealth, a theme that runs across many religions and cultures and that incorporates a major strand of John R. Hinnells’s particular fascination with the Zoroastrians of ancient and modern times, and his more general interest in the positive and life-affirming aspects of religious traditions across many domains. The volume includes seventeen studies by leading scholars exploring ideas of and attitudes to material wealth and its use for promoting spiritual benefits in Zoroastrian, Mithraic, Christian, Buddhist and Islamic traditions.
