In this update to his bestselling text, Daniel J. Siegel, an internationally recognized expert on mindfulness and therapy, explores interdisciplinary conceptions of mind and mindfulness--diving deeply into what it means to be present as a therapist, and how this mindful integration can enhance therapeutic outcomes across modalities. He charts nine domains of integration that arise in our neural networks and in our relationships, which promote bodily regulation, attunement, emotional balance, response flexibility, fear extinction, insight, empathy, morality, and intuition. The author draws thoroughly from the past fifteen years of research in this comprehensive revision to the original text. Despite the book's depth and scientific rigor, it remains a practical, accessible guide, engaging readers in a personal and professional journey into the process of mindful integration that lies at the heart of health and relationships--including the therapeutic bond.
