"ECM: Crossing the Threshold" explores one of humanity's greatest mysteries: near-death experiences (NDEs). Through a journey spanning history, neuroscience, and spirituality, this book delves into personal accounts, scientific studies, and philosophical debates to uncover what happens when consciousness hovers between life and death. With a structure that is both accessible and rigorous, David Sandua guides the reader through the common elements of NDEs —such as a profound sense of peace, tunnels of light, or encounters with transcendent beings— as well as the psychological and emotional impacts that transform those who experience them. The book reviews different cultural and scientific interpretations, the role of faith, the ethical challenges of research, and the influence of NDEs on our view of life, death, and consciousness. Without taking sides, it invites both skeptics and believers to reflect on the meaning of existence, the fear of death, and the possibility of consciousness beyond the physical body. Ultimately, this is a book that challenges certainties, encourages dialogue, and fosters deep contemplation about the limits of reality, opening the door to questions that may never have definitive answers.
