The Buddha said that "everything we need to know about life can be found inside the body". Yet most people's spirituality -- whether Buddhist, Christian, or Jewish -- is cut off completely from their body. In this provocative and groundbreaking San Francisco Chronicle bestseller, Wes Nisker brings readers to a deep understanding and acceptance of their biology and its important role in their spiritual evolution. Using the "Four Foundations of Mindfulness", a traditional Buddhist meditation, the author shows how cutting-edge science is proving the very tenets first offered by the Buddha.Most important, Nisker offers a practical program -- complete with meditations and exercises -- so readers can take their own evolutionary journey into their bodies to find the origins of emotions, desires, and thoughts. Nisker provides a liberating way for each of us to incorporate into our lives the understanding, proven by the latest scientific evidence and foretold in the great traditional teachings of the Buddha, that we are not separate from nature and the evolving universe. Our biology is not our destiny, but our way to enlightenment.
