His apothegm "Cogito, ergo sum" marked the birth of the mind-body problem, while his creation of so-called Cartesian coordinates have made our physical and intellectual conquest of physical space possible.But Descartes had a mysterious and mystical side, as well. Almost certainly a member of the occult brotherhood of the Rosicrucians, he kept a secret notebook, now lost, most of which was written in code. After Descartes's death, Gottfried Leibniz, inventor of calculus and one of the greatest mathematicians in history, moved to Paris in search of this notebook--and eventually found it in the possession of Claude Clerselier, a friend of Descartes. Leibniz called on Clerselier and was allowed to copy only a couple of pages--which, though written in code, he amazingly deciphered there on the spot. Leibniz's hastily scribbled notes are all we have today of Descartes's notebook, which has disappeared.Why did Descartes keep a secret notebook, and what were its contents? The answers to these questions lead Amir Aczel and the reader on an exciting, swashbuckling journey, and offer a fascinating look at one of the great figures of Western culture.

    Its leader was Genesis P-Orridge, co-founder of Psychick TV and Throbbing Gristle, the band that created the industrial music genre. The limited signed cloth edition of Thee Psychick Bible quickly sold out, creating demand for any edition of this 544-page book, which will be available in a handsome smyth-sewn paperback edition with flaps and ribbon. According to author Genesis Breyer P-Orridge, "this is the most profound new manual on practical magick, taking it from its Crowleyan empowerment of the Individual to a next level of realization to evolve our species."

    Written anonymously and published posthumously, as was the author's wish, the intention of this work is for the reader to find a relationship with the author in the spiritual dimensions of existence. The author wanted not to be thought of as a personality who lived from 1900 to 1973, but as a friend who is communicating with us from beyond the boundaries of ordinary life.

    But he did not intend the metaphysics to stand apart from his scientific work, which included important investigations into physics, mathematics, and optics. In this book, Sorell shows that Descarates was, above all, an advocate and practitioner of the new mathematical approach to physics, and that he developed his philosophies to support his discoveries in the sciences.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundreds of key topics, from philosophy to Freud, quantum theory to Islam.

    Ten years after it was first published, this is still the leading resource and reference for all those interested in cross-cultural and current forms of shamanism: now with a new introduction and a list of current shamanic resources.

    This was a special teaching describing the secret wisdom about the nature of the universe and of the soul as well as a path to make the journey, through varied phases of spiritual evolution, from mortal to immortal and from earth to heaven and beyond. The goal is to regain one's divine stature and transcendental place. In its earliest form, originated in Ancient Egypt, it was related to theurgical religious system developed in the priests and priestesses of the Ancient Egyptian city of Anu and the Tree was seen as the source of life. This book explains that teaching, which has been available to all, but missed by those who did not possess the keys to unlock its mystic formula. In this volume the Creation teaching of Anu, the TREE OF LIFE metaphysical teachings, disciplines and techniques, from the hieroglyphic texts, for activating the Tree, are given.

    Volume 1 looks at the discipline's origins in Babylon and Egypt, the creation of geometry and trigonometry by the Greeks, and the role of mathematics in the medieval and early modern periods. Volume 2 focuses on calculus, the rise of analysis in the 19th century, and the number theories of Dedekind and Dirichlet. The concluding volume covers the revival of projective geometry, the emergence of abstract algebra, the beginnings of topology, and the influence of Godel on recent mathematical study.

    A thoroughly revised edition of the much-sought-after early work by Terence and Dennis McKenna that looks at shamanism, altered states of consciousness, and the organic unity of the King Wen sequence of the I Ching.

    A timeless introduction to the field and a landmark in symbolic logic, showing that classical logic can be treated algebraically.

    A child prodigy, Pascal made essential additions to Descartes's work at age sixteen. By age nineteen, he had invented the world's first mechanical calculator. But despite his immense contributions to modern science and mathematical thinking, it is Pascal's wager with God that set him apart from his peers as a man fully engaged with both religious and scientific pursuits.One night in 1654, Pascal had a visit from God, a mystical experience that changed his life. Struggling to explain God's existence to others, Pascal dared to apply his mathematical work to religious faith, playing dice with divinity: he argued for the existence of God, basing his position not on rigorous logical principles as did Aquinas or Anselm of Canterbury, but on outcomes—his famous wager. By applying to the existence of God the same rules that governed the existence and position of the universe itself, Pascal sounded the death knell for medieval "certainties" and paved the way for modern thinking.

    Charing explore the use of one of the major allies of shamans for healing, seeing, dreaming, and empowerment--plant spirits. After observing great similarities in the use of plants among shamans throughout the world, they discovered the reason behind these similarities: Rather than dealing with the “medical properties” of the plants or specific healing techniques, shamans commune with the spirits of the plants themselves. From their years of in-depth shamanic work in the Amazon, Haiti, and Europe, including extensive field interviews with master shamans, Heaven and Charing present the core methods of plant shamanism used in healing rituals the world over: soul retrieval, spirit extraction, sin eating, and the Amazonian tradition of pusanga (love medicine). They explain the techniques shamans use to establish connections to plant spirits and provide practical exercises as well as a directory of traditional Amazonian and Caribbean healing plants and their common North American equivalents so readers can ex-plore the world of plant spirits and make allies of their own.

    He showed that, far from being an exotic novelty, Hinduism was an important, legitimate spiritual tradition with valuable lessons for the West. Pathways to Joy is a selection of 108 of his sacred teachings on Vedanta philosophy. In accessible and powerful prose, Vivekananda illuminates the four classical yoga paths — karma, bhakti, raja, and jnana — for the different natures of humankind. The messages focus on the oneness of existence; the divinity of the soul; the truth in all religions; and unifying with the Divine within. Invaluable and inspiring, the selections also explore karma, maya, rebirth, and other great revelations of Hinduism.

    C. Escher and composer Johann Sebastian Bach, discussing common themes in their work and lives. At a deeper level, the book is a detailed and subtle exposition of concepts fundamental to mathematics, symmetry, and intelligence. Through illustration and analysis, the book discusses how self-reference and formal rules allow systems to acquire meaning despite being made of "meaningless" elements. It also discusses what it means to communicate, how knowledge can be represented and stored, the methods and limitations of symbolic representation, and even the fundamental notion of "meaning" itself. In response to confusion over the book's theme, Hofstadter has emphasized that GEB is not about mathematics, art, and music but rather about how cognition and thinking emerge from well-hidden neurological mechanisms.

    This volume gives methods for training the ego, tuning the heart, and developing will power, all to help one develop and perfect a natural way of being in the world.Excerpt:" For every soul there are four stages to pass through in order to come to the culmination of the ego, which means to reach the stage of the rose. In the first stage a person is rough, thoughtless, and inconsiderate. He is interested in what he wants and in what he likes; as such he is naturally blind to the needs and wants of others. In the second stage a person is decent and good as long as his interests are concerned. As long as he can get his wish fulfilled he is pleasant and kind and good and harmonious, but if he cannot have his way, then he becomes rough and crude and changes completely. There is a third stage, when someone is more concerned with another person's wish and desire and less with himself, when his whole heart is seeking for what he can do for another. In his thought the other person comes first and he comes afterwards. That is the beginning of turning into a rose. It is only a rosebud, but then in the fourth stage this rosebud blooms in the person who entirely forgets himself in doing kind deeds for others."
