We found a 1929 letter in the archives of the American Society for Psychical Research. In it, a young man named Sylvan Muldoon described leaving his physical body for the first time at age twelve, floating above his bed in Burlington, Wisconsin. The letter did not ask for validation. It asked for a collaborator who could help him explain what he had seen. That letter reached Hereward Carrington, a British psychical researcher, and together they produced the most influential body of work on astral projection ever written.
Sylvan Muldoon’s most important books on astral projection are “The Projection of the Astral Body” (1929), “The Case for Astral Projection” (1936), and “The Phenomena of Astral Projection” (1951). These three works form a complete system: a practical manual, a collection of evidence, and a theoretical framework. No other author has matched their combination of personal experience and systematic documentation.
Who Was Sylvan Muldoon and Why Do His Books Matter?

Sylvan Muldoon was born in 1903 in Burlington, Wisconsin. He claimed his first involuntary projection occurred in 1915, when he was twelve years old and bedridden with an illness. By his own count, he experienced over 150 conscious projections before he turned twenty-one.
What separates Muldoon from earlier writers on astral projection is his insistence on the physical sensations of the experience. Earlier occultists like Éliphas Lévi or the Theosophical Society’s Charles Webster Leadbeater described the astral body in abstract, spiritual terms. Muldoon described the vibrations, the paralysis, the sensation of being pulled upward by an invisible cord. He called this cord the “silver cord,” a term he borrowed from Ecclesiastes 12:6 but applied with clinical precision.
Muldoon did not write as a mystic. He wrote as a phenomenologist who happened to be his own primary subject. His books read like case studies, not revelations.
“The Projection of the Astral Body” (1929): The Practical Manual

This is the book that started everything. Muldoon wrote it with Hereward Carrington, who provided the research framework and the skeptical counterweight. Published by Rider & Company in London, it remains in print today.
The book is divided into two parts. The first half describes the mechanics of projection as Muldoon experienced them: the “trance state” that precedes separation, the “catalyst” that triggers it, the “phasic” and “non-phasic” distinctions between partial and full projection. The second half offers instructions for inducing the experience deliberately.
Muldoon’s key insight appears in Chapter 7: the astral body does not separate from the physical body all at once. It extrudes, like a hand emerging from a sleeve. The sensation begins as a vibration in the solar plexus, spreads through the limbs, and culminates in a feeling of weightlessness. The silver cord, he insisted, remains attached at the back of the head.
We have read accounts from practitioners who tried Muldoon’s method and reported the same sequence of vibrations and paralysis. Whether one believes in the astral body or not, the consistency of these reports across decades is striking.
“The Case for Astral Projection” (1936): The Evidence Collection
Seven years after the manual, Muldoon and Carrington published a follow-up that shifted from instruction to proof. “The Case for Astral Projection” gathered accounts from historical sources and contemporary correspondents, organized by type of evidence.
Muldoon categorized projections into three classes: conscious (the projector remembers the experience), semi-conscious (the projector recalls fragments), and unconscious (the projection is witnessed by others but not remembered by the projector). The unconscious category was his most controversial claim. He argued that many people project during sleep without knowing it, and that this explains certain types of “ghost sightings” where the apparition appears to be a living person.
The book includes a chapter on “projection of the double” in non-Western traditions, drawing on reports from India, Tibet, and among Indigenous peoples of North America. Muldoon was not a trained anthropologist, but he was a diligent collector. He found parallels to his own experiences in accounts of the “fetch” in Irish folklore and the “doppelgänger” in German tradition.
“The Phenomena of Astral Projection” (1951): The Theoretical Framework
Muldoon’s final major work, published twenty-two years after the first, attempted to synthesize everything into a coherent theory. He was fifty-eight years old by then, and his health was failing. The book has a different tone from the earlier works: more reflective, less certain.
Here Muldoon proposed his “theory of the astral body as an energy matrix.” He argued that the astral body is not a ghost or a soul in the religious sense, but a “subtle counterpart” that interpenetrates the physical body and can separate under certain conditions. He compared it to the magnetic field around a magnet: invisible, measurable by its effects, and capable of existing independently of its source for short periods.
The book also addresses the limits of projection. Muldoon admitted that he had never been able to project into a locked room and verify the contents. He could not produce the kind of controlled, repeatable evidence that scientific skeptics demanded. This honesty is what makes the book valuable. Muldoon never claimed more than he could support.
How Do Muldoon’s Books Compare to Other Works on Astral Projection?
The most common comparison is with Robert Monroe’s “Journeys Out of the Body” (1971). Monroe, a radio engineer, described his own spontaneous projections and developed a technique based on binaural beats. His work is more accessible to modern readers, but it lacks Muldoon’s systematic rigor.
Monroe’s projections were often chaotic and difficult to control. Muldoon’s were structured and repeatable. Monroe wrote as an explorer. Muldoon wrote as a cartographer.
Oliver Fox, another early twentieth-century projector, published “Astral Projection” in 1939. Fox’s method relied on visualization and dream recall, while Muldoon’s emphasized physical relaxation and the induction of the “trance state.” Both men claimed success, but Muldoon’s documentation is far more detailed.
The Theosophical writers, particularly Leadbeater and Annie Besant, described astral projection as a spiritual discipline requiring years of moral purification. Muldoon rejected this entirely. He argued that projection was a natural physiological process that anyone could experience, regardless of their spiritual development.
Common Misconceptions About Muldoon’s Work
The first misconception is that Muldoon invented the concept of the silver cord. He did not. The image appears in Ecclesiastes, in Plato’s “Timaeus,” and in the Tibetan Book of the Dead. What Muldoon did was describe its physical sensation: a tugging at the back of the skull, a resistance that grows taut as the astral body moves farther from the physical.
The second misconception is that Muldoon’s method is dangerous. Some modern authors warn that astral projection can lead to possession, psychic attack, or mental illness. Muldoon addressed this directly in “The Case for Astral Projection.” He reported no negative effects from his hundreds of projections, and he knew of no verified case where projection caused harm. The danger, he wrote, was not in the practice but in the fear of it.
The third misconception is that Muldoon was a fraud. Skeptics have pointed out that his projections were never independently verified. This is true. But it is also true that Muldoon never sought verification in the way a stage magician would. He offered his experiences as data, not as proof. The reader is free to accept or reject them.
FAQ
Did Sylvan Muldoon actually astral project, or was he lying? Muldoon’s accounts are internally consistent and match the reports of many other projectors. Whether one believes he literally left his body depends on one’s worldview. He himself insisted he was describing real events.
Can I learn astral projection from Muldoon’s books? Many practitioners have succeeded using his methods, particularly the “phasing” technique described in “The Projection of the Astral Body.” The instructions are clear but require patience and consistent practice.
What is the best Muldoon book to start with? “The Projection of the Astral Body” is the most practical. Read it first, then move to “The Case for Astral Projection” for the evidence, and finally “The Phenomena of Astral Projection” for the theory.
The Legacy of Sylvan Muldoon
Muldoon died in 1952, one year after publishing his final book. He never achieved the academic recognition he wanted. His work was ignored by mainstream psychology and dismissed by most parapsychologists.
But his books never went out of print. They have been translated into French, German, Spanish, and Japanese. They are cited in every serious study of out-of-body experience, from the early work of Charles Tart to the modern research of the Monroe Institute.
Muldoon’s great contribution was not proving that astral projection exists. It was describing it so precisely that anyone who experiences it can recognize what is happening. His books are not manuals for magic. They are field guides for a territory that most people visit only in sleep.
For those who want to explore that territory deliberately, Muldoon remains the best guide we have. Read our guide to astral projection for a complete overview of the practice, or consult the glossary of astral projection terms for the key concepts.
