Why is it that, after attaining many of our goals, we are left with a sense that something vital is missing? In his deeply inspiring bestseller, Rabbi Kushner shows us how to live as human beings are meant to. He guides us to a heightened sense of joy, purpose, and meaning, and helps us to redirect our energies toward goals that will bring us lasting happiness and true fulfillment.

    This title presents inspiring science and philosophy in a way that is completely accessible to anyone, to reveal and explore the universal laws and principles that underlie our very existence.

    As a student and young researcher in the 1980s, Gelernter hoped to build a program with a dial marked "focus." At maximum "focus," the program would "think" rationally, formally, reasonably. As the dial was turned down and "focus" diminished, its "mind" would start to wander, and as you dialed even lower, this artificial mind would start to free-associate, eventually ignoring the user completely as it cruised off into the mental adventures we know as sleep.While the program was a only a partial success, it laid the foundation for The Tides of Mind, a groundbreaking new exploration of the human psyche that shows us how the very purpose of the mind changes throughout the day. Indeed, as Gelernter explains, when we are at our most alert, when reasoning and creating new memories is our main mental business, the mind is a computer-like machine that keeps emotion on a short leash and attention on our surroundings. As we gradually tire, however, and descend the "mental spectrum," reasoning comes unglued. Memory ranges more freely, the mind wanders, and daydreams grow more insistent. Self-awareness fades, reflection blinks out, and at last we are completely immersed in our own minds.With far-reaching implications, Gelernter’s landmark "Spectrum of Consciousness" finally helps decode some of the most mysterious wonders of the human mind, such as the numinous light of early childhood, why dreams are so often predictive, and why sadism and masochism underpin some of our greatest artistic achievements. It’s a theory that also challenges the very notion of the mind as a machine—and not through empirical studies or "hard science" but by listening to our great poets and novelists, who have proven themselves as humanity's most trusted guides to the subjective mind and inner self.In the great introspective tradition of Wilhelm Wundt and René Descartes, David Gelernter promises to not only revolutionize our understanding of what it means to be human but also to help answer many of our most fundamental questions about the origins of creativity, thought, and consciousness.

    In this groundbreaking work, three experts—a mycologist, a chemist and a historian—argue persuasively that the sacred potion given to participants in the course of the ritual contained a psychoactive entheogen. The authors then expand the discussion to show that natural psychedelic agents have been used in spiritual rituals across history and cultures. Although controversial when first published in 1978, the book’s hypothesis has become more widely accepted in recent years, as knowledge of ethnobotany has deepened. The authors have played critical roles in the modern rediscovery of entheogens, and The Road to Eleusis presents an authoritative exposition of their views. The book’s themes of the universality of experiential religion, the suppression of that knowledge by exploitative forces, and the use of psychedelics to reconcile the human and natural worlds make it a fascinating and timely read. This 30th anniversary edition includes an appreciative preface by religious scholar Huston Smith and an updated exploration of the chemical evidence by Peter Webster.

    In fact, as this illuminating study demonstrates, psychedelics have been used by human societies in every part of the world for ritual and spiritual purposes for millennia. As Paul Devereux points out, our modern culture is eccentric in its refusal to integrate the profound experiences offered by these natural substances into our own spiritual life and traditions. Modern Western culture's recent experimentation with psychedelic drugs raised the awareness of archaeologists and anthropologists, leading them to recognize the use of hallucinogens in surviving traditional societies and in the archaeological record. Devereux reveals dramatic new evidence - from linguistics, ethnobotany, biology, and other fields - for the psychedelic experiences of various prehistoric cultures, and ponders the implications and effects of psychedelic revelations on our contemporary worldview, linking them to out-of-body and near death experiencs, shamanic trances, even memory and dreaming.

    DeKorne is a "psychonaut" exploring the "imaginal realms" through Personal experimentation and scholarly research. He guides the reader through the history and lore of psychotropic plants, with advice on how to handle the eerie "Entitles" one encounters in "hyperspace". Plants and covered include: Belladonna Alkaloids; Acid Amide; Mescaline; Ayahuasca; DMT from Plants; Psilocybin; and more.

    Its greatest detriment to the world has been its unfettered desire to play with and alter them: science for science's sake, as if it offered the only path to knowledge.According to Lehrer, when it comes to the human brain, the world of art unraveled such mysteries long before the neuroscientists: "This book is about artists who anticipated the discoveries of science who discovered truths about the human mind that science is only now discovering." 'Proust Was a Neuroscientist' is a dazzling inquiry into the nature of the mind and of the truths harvested by its first explorers: artists like Walt Whitman, George Eliot, Auguste Escoffier, Marcel Proust, Paul Cozanne, Igor Stravinsky, Gertrude Stein, and Virginia Woolf. What they understood intuitively and expressed through their respective art forms -- the fallibility of memory, the malleability of the brain, the subtleties of vision, and the deep structure of language -- science has only now begun to measure and confirm. Blending biography, criticism, and science writing, Lehrer offers a lucid examination of eight artistic thinkers who lit the path toward a greater understanding of the human mind and a deeper appreciation of the ineffable mystery of life.

    The Other Brain is the story of glia, which make up approximately 85 percent of the cells in the brain. Long neglected as little more than cerebral packing material ("glia" means glue), glia are sparking a revolution in brain science.Glia are completely different from neurons, the brain cells that we are familiar with. Scientists are discovering that glia have their own communication network, which operates in parallel to the more familiar communication among neurons. Glia provide the insulation for the neurons, and glia even regulate the flow of information between neurons.But it is the potential breakthroughs for medical science that are the most exciting frontier in glia research today. Diseases such as brain cancer and multiple sclerosis are caused by diseased glia. Glia are now believed to play an important role in such psychiatric illnesses as schizophrenia and depression, and in neurodegenerative diseases such as Parkinson's and Alzheimer's. They are linked to infectious diseases such as HIV and prion disease (mad cow disease, for example) and to chronic pain. Scientists have discovered that glia repair the brain and spinal cord after injury and stroke. The more we learn about these cells that make up the "other" brain, the more important they seem to be.Written by a neuroscientist who is a leader in the research to reveal the secrets of these brain cells, The Other Brain offers a firsthand account of science in action. It takes us into the laboratories where important discoveries are being made, and it explains how scientists are learning that glial cells come in different types, with different capabilities. It tells the story of glia research from its origins to the most recent discoveries and gives readers a much more complete understanding of how the brain works and where the next breakthroughs in brain science and medicine are likely to come.

    No new cells. No major changes. If you grew up depressed, angry, sad, aggressive, or nasty, you'd be that way for life. And, as you grew older, there'd be nowhere to go but down, as disease, age, or injury wiped out precious, irreplaceable brain cells. But over the past five, ten, twenty years, all that's changed. Using fMRI and PET scanning technology, neuroscientists can now look deep inside the human brain and they've discovered that it's amazingly flexible, resilient, and plastic. Pictures of the Mind: What the New Neuroscience Tells Us About Who We Are shows you what they've discovered and what it means to all of us. Through author Miriam Boleyn-Fitzgerald's masterfully written narrative and use stunning imagery, you'll watch human brains healing, growing, and adapting to challenges. You'll gain powerful new insights into the interplay between environment and genetics, begin understanding how people can influence their own intellectual abilities and emotional makeup, and understand the latest stunning discoveries about coma and "locked-in" syndrome. You'll learn about the tantalizing discoveries that may lead to cures for traumatic brain injury, stroke, emotional disorders, PTSD, drug addiction, chronic pain, maybe even Alzheimer's. Boleyn-Fitzgerald shows how these discoveries are transforming our very understanding of the "self," from an essentially static entity to one that can learn and change throughout life and even master the art of happiness.

    The Tantric tradition is a unique collection of lesser-known texts, concepts, and meditation practices that are usually made available only to experienced and specially initiated practitioners. The "Vajra World" ( vajradhatu in Sanskrit) is a realm of indestructibility, the level of reality beyond all thought and imagination, all impermanence and change, which a fully realized person knows and inhabits. Used metaphorically, "Vajra World" refers to the traditional culture of Tibet and the unique spirituality that is its secret strength. Topics include:    •  The tantric view of human nature and the external world    •  The special role of the guru, or tantric mentor    •  The preliminary practices that prepare the student for full initiation    •  The major dimensions of Vajrayana practice, including visualizations, liturgies, and inner yogas    •  The tradition of the tulku, or incarnate lama    •  The lore surrounding the death of ordinary people and of saints    •  The practice of solitary retreat, the epitome of traditional Tibetan Buddhism Secret of the Vajra World is the companion volume to the author's earlier book, Indestructible Truth: The Living Spirituality of Tibetan Buddhism. While that book focuses on the history, cosmology, philosophy, and practice of the more public, exoteric side of Tibetan Buddhism, this work treats its more hidden and esoteric aspects as they take shape in Vajrayana. Together, the two volumes provide a broad introduction to the major traditions of Tibetan Buddhism.

    With his own research as well as that of some of the most distinguished scientists of our time, Schäfer moves us from a reality of Darwinian competition to cooperation, a meaningless universe to a meaningful one, and a disconnected, isolated existence to an interconnected one. In so doing, he shows us that our potential is infinite and calls us to live in accordance with the order of the universe, creating a society based on the cosmic principle of connection, emphasizing cooperation and community.

    In this best-selling work, David Richo conveys to his readers just how to do this, based on his many years' experience as a psychotherapist and workshop leader. The author uses as a model the heroic journey whose three phases--departure, struggle, and return--explain what happens in us as we evolve from neurotic ego through healthy ego to the spiritual Self. Departure is explored by helping the reader deal with fear, anger, and guilt, and building self-esteem. Through struggle one learns to maintain boundaries and build intimacy in relationships. And the result is a return to wholeness and love through integration. This thoughtful, approachable work is filled with checklists, diagrams, and literary quotations for meditation, making this a book to read and digest a little at a time for best results. How to Be an Adult will guide readers on their positive journey from fear, through power, to love.

    Instead of struggling even harder to manage or eliminate your anger, you can stop anger feelings from determining who you are and how you live your life. Based on a revolutionary psychological approach called acceptance and commitment therapy (ACT), the techniques in ACT on Life Not on Anger can help you let go of anger and start living your life to the fullest.Your path begins as you learn to accept your angry feelings as they occur, without judging or trying to manage them. Then, using techniques based in mindfulness practice, you'll discover how to observe your feelings of anger without acting on them. Value-identification exercises help you figure out what truly matters to you so that you can commit to short- and long-term goals that turn your values into reality. In the process, anger will lose power over your life-and, amazingly, you'll gain control over your life by simply letting go of your angry feelings.

    Sophisticated without being daunting, brilliantly clear without becoming simplistic, Andrew Olendzki's writing is filled with rich phrases, remarkable images, and the fruits of decades of careful thought. Grounded in profound scholarship, psychological sophistication, and many years of teaching and personal practice, this much-anticipated collection of essays will appeal to anyone looking to gain a richer understanding of Buddhism's experiential tools for exploring the inner world. In Unlimiting Mind, Olendzki provokes fresh and familiar reflections on core Buddhist teachings.

    But much more than autobiography, his story is woven with provocative psychological and philosophical commentary, including input from the likes of Lucretius, Freud, and the metal band Napalm Death. A rare style of intellectual but conversational and poignant but humorous makes for a highly accessible and enjoyable read. As the spiritual account winds down, the book transitions into a more rational exploration of the problems associated with religion—and even with spirituality in general. Everyone from outspoken atheists to moderate believers will be engaged, as David is able to critically evaluate spirituality without the hostility so common among modern atheist writers. At the book’s climax, David develops the popular atheist conversation a little deeper by courageously exploring the implications of nihilism: If our deepest fears about the nature of reality were to be true, could we go on? By the end of Optimistic Nihilism, we begin to suspect that we could—and even wonder if a relatively nihilistic perspective paradoxically makes life more precious than any other scheme. A critical must-read for all students of spirituality, psychology, and humanity.
