After Neil Crenshaw received his doctorate in science education, he began teaching and was coaxed into taking a yoga class taught by one of the faculty members. He says, "Almost immediately a new sense of being opened in me which I had never experienced before." He soon realized he would never have any lasting satisfaction with worldy pursuits, so he began researching the studies of consciousness, spirituality and psychology and interlaced them with his knowledge of science. His research and findings are found in this book.
