Since the introduction of mindfulness-based stress reduction in 1979, secular mindfulness has risen in popularity and used in many settings. This paper explores the ethics of mindfulness-based interventions (MBIs) in light of the contention that secular mindfulness is a misappropriation of Buddhist practice. This paper examines the presumed synonymity between traditional Buddhist mindfulness and secular mindfulness, emphasizing issues of conceptual integrity, postmodern secularism, and modernist globalization. The paper argues, finally, that the two constructs require redefinition.
