Over the past several decades, contemplative practices-most notably mindfulness-have become widely integrated into psychotherapy, healthcare, and education. While these approaches have helped millions reduce stress and improve emotional regulation, many clinicians and practitioners encounter a persistent limitation: technique-based relief sometimes plateaus, leaving deeper patterns of identity-driven suffering intact.Nonduality-Based Therapies offers a careful, secular framework for understanding how nondual orientation-traditionally associated with contemplative traditions-can function within therapeutic contexts without metaphysical claims, spiritual instruction, or ethical overreach.Rather than presenting a new method or doctrine, this book articulates foundational principles, emerging modalities, and clear boundaries for clinical application. It examines when nondual inquiry may be helpful, when it may be destabilizing, and how it can complement established approaches such as mindfulness-based interventions, cognitive therapies, and relapse prevention.Written for clinicians, researchers, and advanced practitioners, this book emphasizes ethical restraint, phenomenological clarity, and empirical humility. It addresses risks, failure modes, and criticisms directly, positioning nonduality-based therapies not as a replacement for existing models, but as a cautious extension of contemporary psychological care.This is not a guide to awakening or enlightenment. It is an invitation to responsible exploration-one grounded in clinical reality, professional accountability, and respect for the limits of what therapy can and should do.
