Of all the things humans rely on plants for - sustenance, beauty, medicine, fragrance, flavor, fiber - surely the most curious is our use of them to change consciousness: to stimulate or calm, fiddle with or completely alter, the qualities of our mental experience. Take coffee and tea: People around the world rely on caffeine to sharpen their minds. But we do not usually think of caffeine as a drug, or our daily use as an addiction, because it is legal and socially acceptable.

We are in the midst of a powerful psychedelic renaissance. After four decades of hibernation, the promise of the psychoactive 60s - that deeper self-awareness, achieved through reality-bending substances and practices, will lead to greater external harmony - is again gaining a major following. The signs are everywhere, from the influence of today's preeminent psychedelic thinker Daniel Pinchbeck, to the renewed interest in the legacy of Terence McKenna, and to the upsurge of collective cultural phenomena like the spectacle of Burning Man.

When a small vial arrives in her mailbox from "Lewis Carroll", Ayelet Waldman is at a low point. Her mood storms have become intolerably severe; she has tried nearly every medication possible; her husband and children are suffering with her. So she opens the vial, places two drops on her tongue, and joins the ranks of an underground but increasingly vocal group of scientists and civilians successfully using therapeutic microdoses of LSD.

A groundbreaking dive into the role psychedelics have played in the origins of Western civilization, and the real-life quest for the Holy Grail that could shake the Church to its foundations.

Embracing the revival of psychedelic research and the discovery of new therapeutic uses, clinical psychologist Dr. Richard Louis Miller discusses what is happening today in psychedelic medicine - and what will happen in the future - with top researchers and thinkers in this field. Dr. Miller and his contributors cover the tumultuous history of early psychedelic research brought to a halt 50 years ago by the US government as well as offering non-technical summaries of the most recent studies with MDMA, psilocybin, LSD, and ayahuasca.

From multiple New York Times best-selling author, neuroscientist, and "new atheist" Sam Harris, Waking Up is for the 30 percent of Americans who follow no religion, but who suspect that Jesus, Buddha, Lao Tzu, Rumi, and the other saints and sages of history could not have all been epileptics, schizophrenics, or frauds.

Holotropic means "moving toward wholeness," from the Greek holos (whole) and trepein (moving in the direction of). The breathwork utilizes the remarkable healing and transformative potential of non-ordinary states of consciousness. These states engender a rich array of experiences with unique healing potential - reliving childhood memories, infancy, birth and prenatal life, and elements from the historical and archetypal realms of the collective unconscious. 

"What should we have for dinner?" To one degree or another, this simple question assails any creature faced with a wide choice of things to eat. Anthropologists call it the omnivore's dilemma. Choosing from among the countless potential foods nature offers, humans have had to learn what is safe, and what isn't. Today, as America confronts what can only be described as a national eating disorder, the omnivore's dilemma has returned with an atavistic vengeance.

From 1990 to 1995 Dr. Rick Strassman conducted U.S. Government-approved and funded clinical research at the University of New Mexico in which he injected 60 volunteers with DMT, one of the most powerful psychedelics known. His detailed account of those sessions is an extraordinarily riveting inquiry into the nature of the human mind and the therapeutic potential of psychedelics. DMT, a plant-derived chemical found in the psychedelic Amazon brew, ayahuasca, is also manufactured by the human brain. In Strassman's volunteers, it consistently produced near-death and mystical experiences.

This mesmerizing, surreal account of the bizarre adventures of Terence McKenna, his brother Dennis, and a small band of their friends, is a wild ride of exotic experience and scientific inquiry. Exploring the Amazon Basin in search of mythical shamanic hallucinogens, they encounter a host of unusual characters - including a mushroom, a flying saucer, pirate Mantids from outer space, an appearance by James and Nora Joyce in the guise of poultry, and translinguistic matter - and discover the missing link in the development of human consciousness and language. 

In the so-called Western diet, food has been replaced by nutrients, and common sense by confusion - most of what we’re consuming today is longer the product of nature but of food science. The result is what Michael Pollan calls the American Paradox: The more we worry about nutrition, the less healthy we seem to become. With In Defense of Food, Pollan proposes a new (and very old) answer to the question of what we should eat that comes down to seven simple but liberating words: "Eat food. Not too much. Mostly plants."

Neither plant nor animal, it is found throughout the earth, the air and our bodies. It can be microscopic, yet also accounts for the largest organisms ever recorded, living for millennia and weighing tens of thousands of tonnes. Its ability to digest rock enabled the first life on land, it can survive unprotected in space and it thrives amidst nuclear radiation. In this captivating adventure, Merlin Sheldrake explores the spectacular and neglected world of fungi: endlessly surprising organisms that sustain nearly all living systems.

There is nothing more essential to our health and well-being than breathing. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences. Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren’t found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of São Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices.

Two New York Times best-selling authors unveil new research showing what meditation can really do for the brain. In the last 20 years, meditation and mindfulness have gone from being kind of cool to becoming an omnipresent Band-Aid for fixing everything from your weight to your relationship to your achievement level. Unveiling here the kind of cutting-edge research that has made them giants in their fields, Daniel Goleman and Richard J Davidson show us the truth about what meditation can really do for us.

In this short book, Sam Harris and Maajid Nawaz invite you to join an urgently needed conversation: Is Islam a religion of peace or war? Is it amenable to reform? Why do so many Muslims seem drawn to extremism? What do words like Islamism, jihadism, and fundamentalism mean in today's world? Remarkable for the breadth and depth of its analysis, this dialogue between a famous atheist and a former radical is all the more startling for its decorum. Harris and Nawaz have produced something genuinely new: they engage one of the most polarizing issues of our time - fearlessly and fully - and actually make progress.
