Book excerpt: The Science of Spirituality is a ground-breaking book that integrates the individual systems of science, psychology, philosophy, spirituality and religion into a unified system that describes the multi-dimensional nature of man and the universe. It provides a more comprehensive description of reality than conventional science can offer and fully explains the mechanisms behind an array of paranormal phenomena that mainstream science chooses to ignore. It explains the science behind religious, spiritual and new-age belief systems, and sheds light on some common misconceptions. The Science of Spirituality systematically describes the mechanisms behind a diverse range of subject matter including: consciousness, sleep and dreams, reincarnation, religion, creation, evolution, space and time, higher dimensions, heaven and hell, ghosts, angels and demons, out of body experiences, near death experiences, clairvoyance, psychic abilities, personal development, meditation and the meaning of life.
