Deep: Lessons Learned from an Enlightened Doctor is the true story of a skeptical mental health professional whose chance encounter with an Indian physician challenges everything he thought he understood about healing, consciousness, and the limits of science. At a conference in Cape Cod, Rob Rice, Ph.D.—a professor, researcher, and mental health professional living with type 1 diabetes—meets Dr. Deep Singh, a physician and practitioner of an ancient healing tradition centered on Nadi. At the time, Rice is struggling with worsening physical symptoms, low energy, and the fear that he may no longer be able to pursue his passion for hiking. What happens during two sessions with Dr. Deep is difficult for Rice to explain—and even harder to dismiss. After experiencing an unexpected improvement in his health and energy, he is left with a question that becomes the driving force of the book: What happened? Rather than abandon skepticism, Rice follows his curiosity. His search for answers leads him into an extraordinary exploration of water, consciousness, sound, vibration, time, ancient healing traditions, and emerging scientific ideas. Along the way, he speaks with physicians, scientists, researchers, and other experts who challenge him to reconsider the boundaries between what we know, what we believe, and what remains unexplained. But Deep is not an argument for abandoning science or accepting extraordinary claims without question. It is an invitation to remain curious. Through remarkable experiences, conversations with Dr. Deep, and reflections with family, friends, and longtime mentors, Rice discovers that some of the most important questions about healing and human existence may not have simple answers. Ultimately, Deep is a story about skepticism and wonder, science and spirituality, control and acceptance—and what can happen when we become willing to explore the mysteries we cannot yet explain. What might we discover if we remain curious long enough?
