Science attempts to explain the world without a creator, spirit or design, constantly seeking new information with which to test its theories. Spirituality holds that the most important aspects of the world are beyond human comprehension. It labels this realm "spirit," "soul," and "God." Who is right? Are humans simply a cluster of cells that eventually dies? Is there a greater plan? Leo Kim asked himself these questions again and again. As a scientist developing new drugs for the treatment of cancer, Kim felt powerless as he watched patients die, an experience that led him on a decades-long quest to understand human existence. Healing the Rift chronicles his metaphysical and scientific journey. Kim reveals how recent scientific breakthroughs led him to the belief that the world is a blending of mind and spirit, explaining the science behind his discovery in entertaining, approachable terms that help readers make sense of their own search for answers.
