"This brilliant and insightful volume explores the psychotherapeutic potential - as well as the shamanic and psychonautic applications - of the 8-circuit model of consciousness, which is probably the most inclusive and comprehensive model of human mind states ever devised. Light years more advanced than Freud, Jung, or any of the other conventional academic theorists, this secret model of consciousness hides on the fringes of cultural thought, due to its association with psychedelic drugs and outlaw philosophers. However, now that that psychedelic medicine is reaching the mainstream, it is time for this extraordinarily efficient, yet esoteric, model of consciousness to reach a wider audience. Douglas Wingate and Rachel Turetzky's 8-Circuit Ascension advances the 9-circuit theory, and brings it up-to-date with the latest developments in psychology, neuroscience, and psychedelic medicine research. This practical handbook and visionary compendium integrates biological, cognitive, humanistic, and transpersonal psychology perspectives into an evolutionary map and developmental model that beautifully blends ancient mystical systems and modern science, as way to fuel personal growth and healing. It's just what our wayward world needs, and the societal and global implications are also explored. Most highly recommended!"
-David Jay Brown, author of Dreaming Wide Awake and The Illustrated Field Guide to DMT Entities

 

"During the recent 'renaissance' in psychedelic clinical research there has been much talk about focusing on rigorous science, and moving past the 'Leary years' when the politics of psychedelics overshadowed and interfered with the pursuit of knowledge. Ironically, now that politics is once again impeding progress in psychedelic research, it’s refreshing to be reminded of knowledge that Leary and others did pass on from those years. Wingate and Turetzky provide us with a fascinating, in-depth and accessible reminder."

"This refreshing book revisits an influential model of consciousness developed by renegade psychologist turned psychedelic guru, Timothy Leary, a figure whose work has always stirred both intrigue and controversy. Leary’s 8-circuit model offers a framework that not only charts typical human development across the lifespan, but also provides an explanation for a range of transpersonal and altered states of consciousness. What’s remarkable about this book is how it updates and aligns Leary’s model with contemporary advances in neuroscience and psychology.

"As interest in psychedelics and non-ordinary states of consciousness resurges in the academic world—particularly for their therapeutic potential—this model offers a valuable lens through which to examine these experiences. More than just a theoretical framework, it presents an evidence-based approach that has the potential to unlock new pathways for exploring and expanding our understanding of consciousness.

"For anyone invested in the science of the mind and the vast complexities of human consciousness, this is a must-read."

-Heather Berlin, PhD, MPH

“A thorough and fascinating review of the theory and application of the 8-Circuit model, with many new insights drawn from recent trends in research and practice. A must-read for anyone interested in the promise of psychedelic-assisted therapy and the inner journey in all its forms. Recommended!"

"Timothy Leary’s work on the eight-circuit model of consciousness didn’t just change my life—it gave me a framework for understanding human potential in ways I never thought possible. This book takes Leary’s groundbreaking concepts and modernizes them, offering a comprehensive guide that could very well be the most important thing you ever read.

"As a psychedelic concierge, I’ve used this model to guide people through their most profound transformations. The idea that each circuit governs a distinct area of consciousness is a master key for unlocking the mind. Knowing which circuit is activated allows me to determine the ideal psychedelic compound to support someone’s growth or healing, whether they’re working through trauma, seeking peak performance, or simply searching for a deeper understanding of themselves.

"What excites me most about this book is the exploration of the eighth circuit. At this level, people consistently report encounters with interdimensional beings, sometimes described as versions of their future selves offering guidance to their present-day lives. The implications of this are staggering. Imagine being able to tap into the wisdom of your future self during moments of crisis or growth. This isn’t science fiction—it’s a phenomenon being witnessed in therapeutic and mystical experiences across the world.

"This book isn’t just an academic discussion of consciousness—it’s a playbook for transformation. It provides a clear structure for how we might navigate and expand our inner worlds. For those of us on the frontier of mental health, personal growth, and psychedelic exploration, this book is an essential guide. Whether you’re a seeker, healer, or adventurer, this is the map you’ve been waiting for."

"In my early 20’s, the ideas and exercises in Wilson’s Prometheus Rising changed the trajectory of how I engaged with the mind and reality. I shared this work with my counter-culture-futurist dad, who in turn handed me his well-loved, underlined copy of Leary’s Exo-Psychology. In that moment, we bridged generations of ideas about consciousness which sparked my life long exploration of neurospiritual practices and self actualization.

Now, with 8-Circuit Ascension, Douglas S. Wingate and Rachel Turetzky, PhD bring the foundational concepts from these past works into the present, synthesizing Leary and Wilson’s groundbreaking concepts with updated frameworks rooted in contemporary research and psychology.

This book doesn’t just explore the 8-circuit model - it is a powerful and vital resource for those seeking healing, transformation, and the evolution of human consciousness, and for the therapists, facilitators, and guides who support them in this process."

"I am floored by the balance struck by Turetzky and Wingate in their brilliant model designed from pioneers Timothy Leary and Robert Anton Wilson’s 8-Circuit Model — a topic so otherwise complex has become both grounded and in-the-world whilst simultaneously transpersonal and true to its’ magickal form.
In a time where the burgeoning field of psychedelic medicines and therapies begs for structures and language towards the deepening of true integration and transformation, comes Wingate and Turetzky’s model. A treasure trove of applications from a wide range of multidisciplinary modalities (an expansive range from mystical to neurobiological) — the authors offer a revival of work by Leary and Wilson that was awaiting application into the Now. And honor it they did — reanimating and expanding upon the lower circuits, the higher dimensions, and the scientific and mythopoetic navigation of this landscape.
Here, Turetzky and Wingate bring answers to the question — How do we understand the psychedelic mind state? And, how can we expand upon current, inadequate models to better explain and aid in traversing the higher circuits of experiences?
Relevant, applicable, and evolving — it is clear to me after reading 8-Circuit Ascension that it be wise for all practitioners and students in the fields of psychonautic/ psychospiritual/ psychedelic therapies and guidance to be well aware of this text."

"This is a very comprehensive and intriguing approach and I believe that it will become an important reference text for psychedelic therapy around the world. It's an important work providing in-depth processes for people working in a clinical setting as well as those facilitating plant spirit ceremonies, and will serve to benefit all those involved."

“After finishing "8-Circuit Ascension," I found myself deeply moved by its insights. My path to discovering these concepts began unexpectedly through Ken Wilber's work, which sparked a personal journey leading me through various fascinating studies, including Stanislav Grof's remarkable research, and, of course, the works of Timothy Leary and others.

"What sets this book apart is how perfectly it weaves these complex threads together and transforming abstract theories into clear and accessible knowledge. The section on the Oral Bio-Survival circuit/The Vegetative-Invertebrate Circuit (C-1) particularly struck me, because it allowed me to reflect into patterns I now recognize in both my own life and in those around me.

"Having spent years exploring consciousness in direct and indirect ways, I truly believe this book opens new doors of understanding – not just for personal growth, but for grasping the deeper nature of human consciousness itself.

I highly recommend this book!”

"Douglas Wingate and Rachel Turetzky’s 8-Circuit Ascension is a well-needed and refreshing update of Timothy Leary and Robert Anton Wilson’s 8-Circuit Brain Model. This book dutifully incorporates recent findings in neuroscience, psychology, and psychedelic therapy to create a valuable resource for researchers and practitioners!”

—Gabriel Kennedy, Author of Chapel Perilous: The Life & Thought Crimes of Robert Anton Wilson

​

"An important and essential work. Building up from the foundations of the 8 Circuit Model as developed by Leary, Wilson and Alli, the authors present a lucid and exciting analysis of the model, with in-depth practical discussion to help with analysis. Tools for integrating the circuits and working directly with them are presented in a clear and concise fashion. This model can be used in countless scenarios - psychological, physical, and intriguingly also to spiritual attainment. The book is deeply referenced and provides a wealth of technical information. As a long time meditator and practitioner of eastern and western esotericism, I found their presentation to be an incredible tool for mapping out where different practices and rituals are most effective. A modern day adaptation of the Tree of Life, or the Enneagram, fit for magicians and mystics of all levels of experience. This should be required reading for all explorers of consciousness.".

-Gregory Peters, author of Yogini Magic, New Aeon Tantra, & other forthcoming titles from Original Falcon Press

"8-Circuit Ascension stands as a wonderful renewal to Timothy Leary’s 8 Circuit Model of Consciousness. Not only does this book deliver up to date neuroscience, but it connects the 8 Circuits with the current surge in using psychedelics as a therapeutic agent. This book should be on the bookshelf of anyone interested in psychology, neurobiology, psychedelics, magick, metaprogramming, and human development. I am grateful to Douglas Wingate and Rachel Turetzky for birthing this refreshing update to the 8 Circuit Model!"
