The Cycle Of Day And Night by Namkhai Norbu is a practical guide to a fundamental practice of the Dzogchen system of Tibetan Buddhism, presented in a clear and direct manner, written by an acknowledged contemporary master of this ancient tradition. Central to Dzogchen, the Great Perfection, is contemplation-the immediate experience of the primordial state of the individual, the unconditioned nature of the mind. This nature of the mind transcends the specific contents of mind, the incessant flow of thoughts reflecting our social, cultural, and psychological conditioning. Based on the teaching by Garab Dorje, the first human master of the Dzogchen lineage, The Cycle Of Day And Night gives a translation of the author's Tibetan Text, together with a commentary drawn from the author's extensive oral explanations. Actual methods are given for entering into contemplation and integrating it with our activities during the 24 hour cycle of day and night. Midwest Book Review
This fascinating book will stay with children every time they gaze up at the night sky. Through vivid pictures and engaging explanations, children will learn about many of the Moon’s mysteries: what makes it look like a silvery crescent one time and a chalk-white ball a few nights later, why it sometimes appears in the daytime, where it gets its light, and how scientists can predict its shape on your birthday a thousand years from now. Next Time You See the Moon is an ideal way to explain the science behind the shape of the Moon and bring about an evening outing no child—or grown-up—will soon forget. Awaken a sense of wonder in a child with the Next Time You See series from NSTA Kids. The books will inspire elementary-age children to experience the enchantment of everyday phenomena such as sunsets, seashells, fireflies, pill bugs, and more. Free supplementary activities are available on the NSTA website. Especially designed to be experienced with an adult—be it a parent, teacher, or friend—Next Time You See books serve as a reminder that you don’t have to look far to find something remarkable in nature.
The statistics are powerful and alarming: Perhaps as many as 6 million Americans suffer from night eating syndrome, or NES, a newly identified eating disorder which describes behavior patterns in which an individual obsessively consumes more than half of his or her daily caloric intake after eight o'clock in the evening. More significant is the further finding that more than 33 percent of morbidly obese individuals, persons who are 100 or more pounds overweight, are affected by this disorder. Experts agree that NES shares characteristics of not only eating disorders but also sleep and mood disorders. Sufferers tend to exhibit symptoms such as feelings of anxiety and guilt, insomnia, or interrupted sleep. Typical NES behaviors include absent appetite during the day, a consistent pattern of eating more food after dinner than during the meal itself, and recurrent episodes of waking and eating throughout the night. This book offers a step-by-step strategy for managing and overcoming this disorder. From this book, you will first learn to identify the signs of NES, and then use journaling exercises to discover what automatic thoughts surround your night eating. Having identified the problematic behaviors, you'íll find out how to break theses patterns with healthier food choices, more structured mealtimes, and a series of relaxation and visualization techniques.
Millions of trees live and grow all around us, and we all recognize the vital role they play in the world’s ecosystems. Publicity campaigns exhort us to plant yet more. Yet until recently comparatively little was known about the root causes of the physical changes that attend their growth. Since trees typically increase in size by three to four orders of magnitude in their journey to maturity, this gap in our knowledge has been a crucial issue to address. Here at last is a synthesis of the current state of our knowledge about both the causes and consequences of ontogenetic changes in key features of tree structure and function. During their ontogeny, trees undergo numerous changes in their physiological function, the structure and mechanical properties of their wood, and overall architecture and allometry. This book examines the central interplay between these changes and tree size and age. It also explores the impact these changes can have, at the level of the individual tree, on the emerging characteristics of forest ecosystems at various stages of their development. The analysis offers an explanation for the importance of discriminating between the varied physical properties arising from the nexus of size and age, as well as highlighting the implications these ontogenetic changes have for commercial forestry and climate change. This important and timely summation of our knowledge base in this area, written by highly respected researchers, will be of huge interest, not only to researchers, but also to forest managers and silviculturists.
From the #1 New York Times bestselling author of Anathem, Reamde, and Cryptonomicon comes an exciting and thought-provoking science fiction epic—a grand story of annihilation and survival spanning five thousand years. What would happen if the world were ending? A catastrophic event renders the earth a ticking time bomb. In a feverish race against the inevitable, nations around the globe band together to devise an ambitious plan to ensure the survival of humanity far beyond our atmosphere, in outer space. But the complexities and unpredictability of human nature coupled with unforeseen challenges and dangers threaten the intrepid pioneers, until only a handful of survivors remain . . . Five thousand years later, their progeny—seven distinct races now three billion strong—embark on yet another audacious journey into the unknown . . . to an alien world utterly transformed by cataclysm and time: Earth. A writer of dazzling genius and imaginative vision, Neal Stephenson combines science, philosophy, technology, psychology, and literature in a magnificent work of speculative fiction that offers a portrait of a future that is both extraordinary and eerily recognizable. As he did in Anathem, Cryptonomicon, the Baroque Cycle, and Reamde, Stephenson explores some of our biggest ideas and perplexing challenges in a breathtaking saga that is daring, engrossing, and altogether brilliant.
