Our guest on ST Medical Monday is Dawn Mauricio, who's been practicing and studying vipassanā meditation since 2005, and who now works as a meditation retreat teacher. (You'll find her online at dawnmauricio.com.) She joins us to discuss her new book, "Mindfulness Meditation for Beginners: 50 Meditations to Practice Awareness, Acceptance, and Peace." As was noted of this book by Jack Kornfield, the author of "A Path with Heart": "[This is] an elegantly simple, wise, and practical approach to mindfulness. In troubled times, these practices are enormously valuable -- they help steady the heart, heal the body, and calm the mind."
