In Egypt during the first centuries CE, men and women would meet discreetly in their homes, in temple sanctuaries, or insolitary places to learn a powerful practice of spiritual liberation. They thought of themselves as followers of Hermes Trismegistus, the legendary master of ancient wisdom. While many of their writings are lost, those that survived have been interpreted primarily as philosophical treatises about theological topics. Wouter J. Hanegraaff challenges this dominant narrative by demonstrating that Hermetic literature was concerned with experiential practices intended for healing the soul from mental delusion. The Way of Hermes involved radical alterations of consciousness in which practitioners claimed to perceive the true nature of reality behind the hallucinatory veil of appearances. Hanegraaff explores how practitioners went through a training regime that involved luminous visions, exorcism, spiritual rebirth, cosmic consciousness, and union with the divine beauty of universal goodness and truth to attain the salvational knowledge known as gnôsis.

Hermetic spirituality in late antiquity was an experiential practice and personal transformation grounded in powerful techniques for consciousness alteration.

Western esotericism has been a pervasive presence in Western culture from late antiquity to the present day, but until recently it was largely ignored by scholars and surrounded by misconceptions and prejudice. This accessible guide provides readers with the basic knowledge and tools that will allow them to find their way in this bewildering but fascinating field. What is it that unites phenomena as diverse as ancient gnosticism and hermetism, the "occult sciences" of astrology, alchemy, and magic, rosicrucianism, as well as Christian theosophy, occultism, spiritualism, and the contemporary New Age spiritualities? What can the study of them teach us about our common cultural and intellectual heritage, and what is it that makes them relevant to contemporary concerns? How do we distinguish reliable historical knowledge from legends and fictions about esoteric traditions? These and many other questions are answered clearly and succinctly, so that the reader can find his way into the labyrinth of Western esotericism and out of it again.

"Hermes in the Academy" commemorates the tenth anniversary of the Center for History of Hermetic Philosophy and related Currents (GHF) at the University of Amsterdam. The center devotes itself to the study of Western esotericism, which includes topics such as Hermetic philosophy, Christian kabbalah and occultism. This volume shows how, over the past ten years, the GHF has developed into the leading international center for research and teaching in this domain.

The neglected history of how intellectuals since the Renaissance have approached ideas of the occult which challenged biblical religion.

From rumours about gnostic orgies in antiquity to the explicit erotic symbolism of alchemical texts, from the subtly coded eroticism of medieval kabbalah to the sexual magic practiced by contemporary occultists and countercultural translations of Asian Tantra, the history of Western esotericism is rich in references to the domains of eros and sexuality. This volume, which brings together an impressive array of top-level specialists, is the first to analyze the eroticism of the esoteric without sensationalism or cheap generalizations, but on the basis of expert scholarship and attention to textual and historical detail. While there are few other domains where the imagination may so easily run wild, the various contributions seek to distinguish fact from fiction--only to find that historical realities are sometimes even stranger than the fantasies. In doing so, they reveal the outlines of a largely unknown history spanning more than twenty centuries.

Hermeticism, or alchemy, is the ancient, primordial mystery science of nature through which people in all times and places have, for the sake of world evolution, sought to unite Heaven and Earth--divinity, cosmos, earth, and humanity, as a single whole. Selfless, intimate, dedicated to healing and harmony, Hermeticism has accompanied and sustained every religious epoch and revelation. It may be found in all historical cultures, from the traditions of India and China in the East to the Judeo-Christian West. It could even be said that Hermeticism is the primal cosmological revelation and the common ground of all spiritual traditions. Nevertheless, in the great revival of mystical, esoteric traditions and practices during the last century, Hermetic tradition--in fact, Nature herself--has been largely ignored. Today, when the Earth seems most under attack, Green Hermeticism is especially appropriate. The book explores not only the ancient Masters' inner science, but also their science of Nature. During spring and summer 2006, Pir Zia Khan convened a series of gatherings to begin to unfold the contemporary meaning of ancient, sacred science for our time. Green Hermeticism is a partial record of that meeting. Peter Lamborn Wilson, explores the many ramifications of the alternative worldview offered by Hermeticism; Christopher Bamford provides a broad historical overview of the tradition from the Ancient Mysteries to contemporary manifestations of the alchemical tradition; while Kevin Townley brings a practical dimension to the gathering teaching the preparation of herbal elixirs and demonstrating that cosmology and philosophy can become a truly healing path for the Earth. Green Hermeticism is necessary reading for anyone seeking a spiritual and cultural path for the healing of the current ecological and cultural crisis. "In Alchemy, there is an injunction to quicken, or revive, the dead, which is illustrated by a dead tree growing verdant again. That is exactly what this wonderful and rare work does in awakening human consciousness to its Divine potential and Ultimate Destiny. Art thus helps Nature to achieve its ideal Perfection. The authors must be congratulated for their insightful words. I wholeheartedly recommend reading it again and again, and again." --Stanislas Klossowski de Rola, author Alchemy: The Secret Art and The Golden Game: Alchemical Engravings of the Seventeenth Century "Environmental solutions today are largely technical, but the planetary crisis is also a crisis of soul--or better yet, of the Imagination. Too tricky for religion, too poetic for reductionist science, Green Hermeticism reheats a prophetic imagination still in love with the material world--a new alchemy of ancient nature." --Erik Davis, author, The Visionary State: A Journey through California's Spiritual Landscape "Just when you felt numb and disenfranchised, thinking the world had become bleak and dead, along comes this rare, much needed book to remind us that there is still some sanity, depth, and creative energy percolating up from the heart of Reality. Thank God (and the Goddess Nature) for this smart and inspiring breath of fresh air! Green Hermeticism is where the wasteland ends--and where the world becomes re-enchanted with genuine living thought that goes beyond superficialities. It's a rare pleasure to be in the presence of living minds who actually know something wonderful and have not been deadened by the opiates of capital or the tenure track. Very highly recommended." --David Fideler, publisher (Phanes Press) editor (Alexandria), author of Jesus Christ, Sun of God and translator of Love's Alchemy: Poems from the Sufi Tradition (with Sabrineh Fideler) "The publication of Green Hermeticism has the sense we so rarely get, of a genuine moment in cultural history. It is not just the eloquence of its authors' knowledge and arguments or that they are showing us, once again, the depth and range and beauty of alchemy, and the Hermetic tradition, and what Peter Lamborn Wilson calls Romantic Science. Nor is it even the links they establish between the Hermetic tradition and ecology, and the value of a science that perceives the world as alive rather than a machine. What makes this work significant is the sense that it shows us how we can use these ideas and knowledge to create a genuine counter to destruction and despair, an alchemy of our politics as well as of our spirit." --Rachel Pollack, author of 78 Degrees of Wisdom: A Book of Tarot "Green Hermeticism reminds us that the art of the Great Work is to enter more deeply into the dynamic and practical wisdom of the universe, which is our laboratory, where work and prayer combine. When we engage with the All, we know ourselves to be one kindred with all in the viriditas--God's greening power--where body, soul, and spirit honor each other." --Caitlín & John Matthews, authors of Walkers Between the Worlds: The Western Mysteries from Shaman to Magus
