The work being done on light in theology as reflected in the Bible and Judaeo Christian tradition, philosophy, physics, medicine and near-death experiences is directing us to a revolutionary breakthrough in terms of a new model – a new approach to reality. Progress in all of these areas of human curiosity is being driven by brilliant and original insights into the very nature of the foundational stuff of the universe – light – an elusive, pervasive, something or someone!This new approach to reality sees the Mind -Body – Spirit connection as an essential insight if we are to even begin to comprehend the inner and outer worlds that together reveal to us what exists – what is truly real.After more than two decades of reading other’s works, my own experiences, and pondering, I came to the conclusion that it made sense to use the Mind – Body – Spirit connection as the basic framework for presenting the human experience of light in the Bible and Judaeo Christian tradition, philosophy, physics, medicine, and near-death experiences. Light is the ultimate stuff of all that exists as both a something and a someone, calling each of us into life.If light is indeed the foundational, basic stuff of all that exists then it is easy to understand why light based medical technologies and medications are the most effective and the non-invasive form of medicine practiced in the early twenty-first century. They are utilizing the basic constituent element of the universe – light – in one or another of its many forms.Long before I was involved in a serious study of the phenomenon of light, I recognized in myself an intense sensitivity to light in all its forms. From my recollection of the early years of my life, my sleep patterns have always been highly affected by light. Even if I had been sleeping for eight hours or so before the time of my rising, if the rising time was prior to natural daylight I found it very difficult to get out of bed and still do. As I am aging into my mid-seventies my body clock winds down sooner at the end of natural daylight but awakens as soon as natural daylight comes streaming into my bedroom window.I have always wanted to be in natural daylight as much as possible during the day either outdoors, or if indoors, working by a window with abundant natural light. My career as a public school teacher, principal, and college professor found me maximizing natural light in my classrooms and requesting office space with abundant windows as sources of natural light. I seldom turned on the artificial lights, which were either incandescent or limited spectrum fluorescent, until forced to do so by natural darkness when my work schedule kept me there past the end of daylight. I have always felt good in the light. It has been a lifelong medicine for me.In 1993, due to a persistent “lazy eye” condition in my right eye and the beginning deterioration in acuity of vision in my left eye, I sought a new phototherapy treatment recommended by my Optometrist, Dr. Earl Lizotte, who had been working in the field of Syntonic Optometry since the late 1980’s. It was during this treatment that I was told of the work of Dr. Jacob Liberman and made aware of his book, Light Medicine of the Future. Dr. Lizotte was also exploring the work of Arthur Zajonc on the history of light as described in Zajonc’s 1993 book, Catching the Light. Zajonc is a Professor of Physics at Amherst College and a specialist in Quantum Physics.These two works filled in the missing pieces of my own study of light that had formally begun with my initial work on the writing of Pierre Teilhard deChardin in the mid 1970’s.Teilhard de Chardin was a Jesuit priest, scientist, and philosopher, who along with Zajonc and other interdisciplinary synthesizers see science, theology, mysticism, religion, and ecology as fundamentally interrelated. Each of these areas reveals a different aspect of reality. Collectively they give us the most complete picture of reality we can attain.With the addition of near-death studies, the scope of my study on light came to completion in 2006, however, my research on Light as a Someone and a something continues.The Mind-Body-Spirit connection in the Medicine of Light originates and is confirmed in the work of synthesizers such as Arthur Zajonc and Pierre Teilhard de Chardin. It is my basic approach to reality in this initial article on the Medicine of Light, and in a series of articles on specific applications of light based technologies, therapies, and medications.
