There would be no life on Earth without light from the Sun, and life would not be as highly evolved as it is had it not made the best use of light's energy and information for using photosynthesis, biological clocks, and vision. In Light and Life, Michael Gross explores six major aspects of the complex and fascinating interplay between light and life, ranging from the mythical role of the Sun in ancient cultures to the latest advances in scientific research, covering photosynthesis, bioluminescence, vision, perception, and biological clocks. - ;Light, like no other physical phenomenon, is linked in a wide variety of ways with the biological phenomenon of life. We can read this page because light is reflected from it, and carries the information to the retina; the oxygen we breathe was produced by photosynthesis; our sense of alertness relies on our biological clock, set using the cues of light and dark. Michael Gross explores the symbiotic relationship of light and life in this intriguing and entertaining book. Starting with astronomy and our relationship with the Sun and dependence on photosynthesis, he then turns to some of the stranger outcomes of the relationship - bioluminescent creatures, and their evolutionary significance. Finally he looks at the influence of light on biological time-keeping, the focus of much current scientific research. Life would not be here without light, and it would not have evolved as it has done had it not made the best possible use of light's energy and information content for using photosynthesis, biological clocks, and vision. This book explores all these aspects of the fascinating interplay of these two phenomena in a lively manner using many intriguing examples. -

The Gospel of John is the most deeply spiritual of the four gospels. This writing is filled with rich images and profound truths, but John notes that his aim in writing the gospel is that readers will not only believe in Jesus Christ, but that they “may have life in his name.” Adults, youth, and children alike can experience a season of spiritual growth and life-changing renewal in Adam Hamilton’s six-week, DVD-series, John: The Gospel of Light and Life. You’ll follow the life, ministry, death, and resurrection of Jesus through the Gospel of John and understand the context of some of the best-known verses in the New Testament. Everything you need to lead small groups of all ages is available for this special study including the entire Gospel of John in the CEB translation printed in the book.

The secrets of light — Your pathway to a state of presence Seeking a state of presence: The most important things in life are our health and happiness. Yet most of us are neither healthy nor happy. We have been led to believe that if we think ahead and make the right choices, we can manifest our dreams. Yet despite our best efforts, we still have more disease and discontent than ever before. Is it possible that our essential ideas about life are flawed? Can we learn how to get into the zone or a flow state? Is light the key to finding a state of presence? Living in the light: We are all aware of the impact of sunlight on a plant’s growth and development. But few of us realize that a plant actually “sees” where light is emanating from and positions itself to be in optimal alignment with it. This phenomenon, however, is not just occurring in the plant kingdom — humans are also fundamentally directed by light. The intersection of science and spirituality: In Luminous Life, Dr. Jacob Israel Liberman integrates scientific research, clinical practice, and direct experience to demonstrate how the luminous intelligence we call light effortlessly guides us toward health, contentment, and a life filled with purpose. If you have read Barbara Brennan’s Hands of Light or Light Emerging, you’re going to love Jacob Liberman’s Luminous Life.

B.K.S. Iyengar--hailed as "the Michelangelo of yoga" (BBC) and considered by many to be one of the most important yoga masters--has spent much of his life introducing the modern world to the ancient practice of yoga. Yoga's popularity is soaring, but its widespread acceptance as an exercise for physical fitness and the recognition of its health benefits have not been matched by an understanding of the emotional, intellectual, and spiritual development that the yogic tradition can also offer. In Light on Life, B.K.S. Iyengar brings readers this new and more complete understanding of the yogic journey. Here Iyengar explores the yogic goal to integrate the different parts of the self (body, emotions, mind, and soul), the role that the yoga postures and breathing techniques play in our search for wholeness, the external and internal obstacles that keep us from progressing along the path, and how yoga can transform our lives and help us to live in harmony with the world around us. For the first time, Iyengar uses stories from his own life, humor, and examples from modern culture to illustrate the profound gifts that yoga offers. Written with the depth of this sage's great wisdom, Light on Life is the culmination of a master's spiritual genius, a treasured companion to his seminal Light on Yoga.

Photobiology - the science of light and life - begins with basic principles and the physics of light and continues with general photobiological research methods, such as generation of light, measurement of light, and action spectroscopy. In an interdisciplinary way, it then treats how organisms tune their pigments and structures to the wavelength components of light, and how light is registered by organisms. Then follow various examples of photobiological phenomena: the design of the compound eye in relation to the properties of light, phototoxicity, photobiology of the human skin and of vitamin D, photomorphogenesis, photoperiodism, the setting of the biological clock by light, and bioluminescence. A final chapter is devoted to teaching experiments and demonstrations in photobiology. This book encompasses topics from a diverse array of traditional disciplines: physics, biochemistry, medicine, zoology, botany, microbiology, etc., and makes different aspects of photobiology accessible to experts in all these areas as well as to the novice.
