In 1968, a psychologist at the University of California Medical Center sat down with a woman he called Miss Z. She reported floating near the ceiling of a room while her body remained on the bed. Instead of diagnosing delusion, Charles Tart prepared a series of hidden target numbers placed on a high shelf. He told her to read them while she was “out.” Charles T. Tart is known for founding the rigorous scientific investigation of altered states of consciousness, out-of-body experiences (OBEs), and transpersonal psychology. He introduced the framework of state-specific sciences and the concept of the consensus trance.
He gave us a language for what happens when the room shifts. For a practitioner of the occult, the map of consciousness is often drawn in metaphor and poetry. Tart insisted it could also be drawn in data. The result is a body of work that remains the most useful bridge between the laboratory and the temple.
The Laboratory of the Invisible

Charles T. Tart was born in 1937 in New Jersey. He trained as an electrical engineer at MIT before pivoting to psychology. That engineering background left a permanent mark. He approached the mind as a system that could be understood, calibrated, and tested. He earned his PhD from Duke University in 1963, studying under J.B. Rhine, the father of modern parapsychology.
Tart’s first major contribution was methodological. In 1968, he published the first rigorous experiment on an out-of-body experience. Miss Z was capable of inducing OBEs at will. Tart designed a protocol where a five-digit number was written on a target and placed on a high shelf. If Miss Z could correctly report the number while “out of body,” the phenomenon would have empirical support. She correctly reported the number 25132.
This experiment did not “prove” the soul. It proved, to a reasonable scientific standard, that something was happening that could not be dismissed as simple fantasy. For the first time, a practitioner who floated to the ceiling could open a peer-reviewed journal and find their own experience described in cold, clinical language. The academy had taken notice.
In 1969, Tart edited the seminal anthology Altered States of Consciousness. The book gathered research on hypnosis, meditation, biofeedback, and psychedelics into a single framework. It became a founding text for what would later be called transpersonal psychology. He followed it with Transpersonal Psychologies in 1975 and States of Consciousness in the same year. Each book deepened the argument that consciousness was not a single thing but a series of learnable, navigable states.
His later work included remote viewing research for the military through the Stargate Project at SRI International. The project proved that statistically significant anomalous cognition was possible under controlled conditions. Tart also spent decades at the University of California, Davis, where he trained a generation of researchers to look at the invisible without losing their scientific composure.
What the Consensus Trance Means for the Magician

That history explains why his concept of the consensus trance matters. Tart argued that ordinary waking consciousness is not a baseline. It is a learned state, a cultural hypnotic induction. We are trained from birth to filter out enormous ranges of perception. He called this the consensus trance: a mutually agreed-upon hallucination of what reality is.
For the occultist, this is the most practical idea Tart ever produced. If normal reality is a trance, then magic is the act of inducing a different trance. When you cast a circle, you are not just performing a ritual. You are initiating a discrete state of consciousness, or d-SoC. The words, the incense, the gestures: all of them are induction tools designed to break one state and build another.
Tart’s framework implies the world is more malleable than we are taught. The consensus trance is maintained by agreement. Withdraw your agreement, even for a moment, and the walls thin. The practitioner stops fighting the “unreal” nature of visions and starts working with the specific architecture of the mind. You cannot study the dream state from within the waking state. You must enter the dream.
The consequence is practical and immediate. If a vision feels faint or a ritual feels flat, the problem is not the spirits. The problem is the induction. The transfer function from one state to another was not clean.
How We Apply Tart’s Map
If the consensus trance is a cage, Tart’s work provides the schematics for the lock. We use his framework in three specific ways.
First, his OBE protocol remains the gold standard for anyone training to practice astral projection. He demonstrated that physical targets could validate non-physical experience. And if you have been saying AS-tral pro-JEK-shun, Tart never cared. He cared about the data. The target number method gives the practitioner a concrete goal: set a symbol in the physical space, cross the threshold, and bring back a report. The reports are not always accurate. But the structure gives the experience a spine.
Second, his model of discrete states tells us to prepare the apparatus. You cannot shift from waking to a magical state smoothly unless you understand the transfer function. Tart broke this down precisely: you have to disrupt the old state, the consensus trance. You then construct the new state, the ritual space. Finally, you stabilize it. A sloppy induction produces a sloppy state. This is why we light matches in a specific order. This is why we use the same words. Repetition builds the rails for the state change.
Third, his work on state-specific sciences implies that knowledge gained in one state is not fully translatable to another. A vision experienced in deep meditation does not survive intact when you return to consensus trance. You must immediately translate it. This is why we write down our work immediately after closing a session. The dream logic fades. The precise image that seemed so clear begins to dissolve. Tart gave us the reason. The two states speak different languages.
Two Architects of Transpersonal Psychology
Tart was not alone in this exploration. He stood on the shoulders of William James, who had written The Varieties of Religious Experience in 1902 and insisted that the study of mystical states was a legitimate branch of psychology. Tart was James’s empirical heir. He took James’s open-ended observations and built a laboratory around them.
His contemporary was Stanislav Grof. Both were architects of transpersonal psychology. Grof’s research with LSD and holotropic breathwork mapped the perinatal and transpersonal dimensions of the psyche. Where Grof was the explorer of the deep ocean, Tart was the cartographer of the coastlines. Grof dove into the experience. Tart designed the instruments.
John C. Lilly, who studied consciousness using isolation tanks, shared Tart’s conviction that consciousness was a continuum. Both understood that the brain was a reducing valve, not a generator. The difference was temperament. Lilly was the mad scientist who pushed himself into the void. Tart was the sober methodologist who built the protocols so that others could follow.
The three men created the architecture of modern transpersonal thought. Tart’s contribution was the insistence on rigor. Without him, the field might have remained entirely in the realm of poetry and anecdote.
What People Get Wrong About Tart
Because his work bridged the laboratory and the séance, it has been consistently misunderstood.
Tart believed in the survival of the soul. He did not. He explicitly argued that OBEs were a natural, demonstrable phenomenon that did not require a theological conclusion. His agnosticism is the reason his work survives. He refused to leap from data to dogma.
His work is outdated. It is foundational. The neuroscience of consciousness, the study of the default mode network, and the modern research into meditation have all confirmed his basic architecture. The terms changed. The map did not. The field called “consciousness studies” today owes a direct debt to his 1969 anthology.
He was a mystic. He was a methodologist. He built the box so that others could dream inside it without being evicted by the academy. His personal practices, which included meditation and dream work, were secondary to his role as a documentarian of states.
He was a fringe figure. He was tenured at a major university. He published in mainstream journals. His work on the consensus trance is as uncomfortable for the materialist as it is for the spiritualist. It challenges both sides equally.
FAQ
Did Charles Tart prove the existence of the soul? No. He proved that OBEs are a real, measurable phenomenon. He insisted that this was a separate question from the existence of a soul or an afterlife.
What is the difference between Charles Tart and Stanislav Grof? Grof explored the content of altered states using psychedelics and breathwork. Tart focused on the structure of those states and the methodological framework for studying them scientifically. Grof was the diver. Tart was the architect of the diving bell.
Is Tart’s work considered pseudoscience? Mainstream psychology has largely ignored it, but his methodology is rigorous. He is critiqued for his subject matter, not his method. The Stargate Project proved his remote viewing protocols produced statistically significant results. The rejection is cultural, not scientific.
What is the “consensus trance” in simple terms? It is the hypnosis of everyday life. We are conditioned to accept a narrow band of perceptions as “real.” Tart argued that other cultures and magical traditions deliberately train to break this trance. The goal of much occult practice is to wake up from a dream we forgot we were having.
The Map and the Territory
Charles Tart gave us a map for the journey. He named the consensus trance, built the state-specific sciences, and showed that the door between the worlds can be measured as well as felt. The territory remains.
