Notes on Contributors 262 This volume is dedicated to the anonymous men and women, shamans and curanderas of the Amazon rain forest, who preserved and passed on the knowledge and practices of ayahuasca, vine of the spirits, for our benefit and ail sentient beings. Introduction AmAZonlAn ViriE 7 OF Visions RALPH METZNER, PH.D. Ayahuasca is an hallucinogenic Amazonian plant concoction that has been used by native Indian and mestizo shamans in Peru, Colombia, and Ecuador for healing and divination for hundreds, perhaps thou- sands, of years. It is known by various names in the different tribes, including caapi, natema, mihi, and yage. The name ayahuasca is from Quechua, a South American Indian language: huasca means "vine" or "liana" and aya means "souls" or "dead people" or "spirits." Thus "vine of the dead," "vine of the souls," or "vine of the spirits" would all be appropriate English translations. It is however slightly mislead- ing as a name, since the vine Banisteriopsis caapi is only one of two essential ingredients in the hallucinogenic brew, the other one being the leafy plant Psychotria viridis, which contains the powerful psychoac- tive dimethyltryptamine (DMT). It is the DMT, derivatives of which are also present in various other natural hallucinogens, including the magic mushroom of Mexico, that provides visionary experiences and thus access to the realm of spirits and the souls of deceased ancestors. DMT is not orally active but is metabolized by the stomach enzyme monoamine oxidase (MAO). Certain chemicals in the vine inhibit the action of MAO and are therefore referred to as MAO-inhibitors: their I 2 INTRODUCTION: AMAZONIAN VINE OF VISIONS 2 - presence in the brew makes the psychoactive principle available and allows it to circulate through the bloodstream into the brain, where it triggers the visionary access to otherworldly realms and beings. The details of this remarkably sophisticated indigenous psychoactive drug delivery system, and the history of its discovery by science, will be described and explored in this volume. As a plant drug or medicine, ayahuasca is one of a group of simi- lar substances that defy classification: they include psilocybin derived from the Aztec sacred mushroom teonanacatl, mescaline derived from the Mexican and North American peyote cactus, DMT and various chemical relatives derived from South American snuff powders known as epena or cohoba, the infamous LSD derived from the ergot fungus that grows on grains, ibogaine derived from the root of the African Tabernanthe iboga tree, and many others. As plant extracts or synthe- sized drugs, these substances have been the subject of a large variety of scientific research approaches over the past fifty years, particularly as to their potential applications in psychotherapy, in the expansion of consciousness for the enhancement of creativity, and as amplifi- ers of spiritual exploration. They have been called psychotomimetic ("madness mimicking"), psycholytic ("psyche loosening"), psychedelic ("mind manifesting"), hallucinogenic ("vision inducing"), and entheo- genic ("connecting to the sacred within"). The different terms reflect the widely differing attitudes and intentions, the varying set and setting with which these substances have been approached. We will be describ- ing the Western scientific psychological and psychiatric approaches to ayahuasca in this book also. The concepts of shaman and shamanism are not peculiar to South America; the terms themselves are derived from a Siberian language. In recent years they have come to be used for any practice of healing and divination that involves the purposive induction of an altered state of consciousness, called the "shamanic journey," in which the shaman enters into "nonordinary reality" and seeks knowledge and healing power from spirit beings in those worlds. The two most widespread shamanic techniques for entering into this altered state are rhythmic drumming, practiced more in the Northern Hemisphere (Asia, America, and Europe), and hallucinogenic plants or fungi, practiced more in INTRODUCTION: AMAZONIAN VINE OF VISIONS 3 - the tropics and particularly in Central and South America. Ayahuasca is widely recognized by anthropologists as being probably the most powerful and most widespread shamanic hallucinogen. In the tribal societies where these plants and plant preparations are used, they are regarded as embodiments of conscious intelligent beings that only become visible in special states of consciousness, and who can function as spiritual teachers and sources of healing power and knowledge. The plants are referred to as "medicines," a term that means more than a drug: something like a healing power or energy that

    ‘Shameless’ Thanks Fans for Season 9 Return 06.07.2018 Shameless star Emmy Rossum and other cast members thank fans for their love and support in Showtime's teaser announcing a ninth season of the series. The promo features a nostalgic montage that looks back at key moments from the show. When it returns, political fervor hits the South Side and the Gallaghers take justice into their own hands. Frank (William H. Macy) sees financial opportunity in campaigning and gives voice to the underrepresented South Side working man. Fiona (Rossum) tries to build on her success with her apartment building and takes an expensive gamble hoping to catapult herself into the upper echelon. Meanwhile, Lip (Jeremy Allen White) distracts himself from the challenges of sobriety by taking in Eddie's niece, Xan (Scarlet Spencer). Ian (Cameron Monaghan) faces the consequences of his crimes as the Gay Jesus movement takes a destructive turn. Debbie (Emma Kenney) fights for equal pay and combats harassment; and her efforts lead her to an unexpected realization. Carl (Ethan Cutkosky) sets his sights on West Point and prepares himself for cadet life. Liam (Christian Isaiah) must develop a new skillset to survive outside of his cushy private school walls. Kevin (Steve Howey) and V (Shanola Hampton) juggle the demands of raising the twins with running the Alibi as they attempt to transform the bar into a socially conscious business. Shameless will premiere September 9 at 9 p.m. Immediately afterward at 10 p.m., Showtime will debut new half-hour comedy series Kidding starring Jim Carrey in his first series regular role in more than two decades, and reuniting him with director Michel Gondry (Eternal Sunshine of the Spotless Mind).

A veteran transpersonal psychologist and family counselor, Dr. Stone teaches us how our entire understanding of ourselves and others is completely changed when we integrate our soul into the way we live our lives. Based on eighteen years of Dr. Stone's practice, this book is not a psychological approach to spirituality. It is rather a spiritual approach to the psychology of everyday living.At the heart of Soul Psychology is emotional healing through the dismantling of the "negative ego," a psychological cancer that prevents us from acting in accordance with our soul's true nature and purpose. This negative energy drives us to find our security outside of ourselves; whereas the only true security is one that is grounded in having a right relationship with self and a right relationship with the Divine. To guide us onto this path of spiritual ascension, Soul Psychology offers a stimulating new viewpoint that expands the boundaries of traditional spiritual practice, providing a wealth of accessible and powerful meditations and exercises, including- The six-step process for healing and spiritualizing emotions- The spiritual science of the seven rays and the twenty-two chakras- Methods for clearing negative psychic energies that inhibit soul growth- The one hundred most common pitfalls and traps on the spiritual pathFrom the Trade Paperback edition.
