The Gateway Process

In 1983 a U.S. Army intelligence officer tried to explain altered consciousness using neuroscience, physics, meditation, mysticism, and the Monroe Institute's Hemi-Sync system. The document is real. Its conclusions are much stranger — and much less settled — than the memes.

Start with what is actually documented

Analysis and Assessment of Gateway Process is a U.S. Army memorandum dated June 9, 1983. Lt. Col. Wayne M. McDonnell wrote it for the U.S. Army Operational Group under INSCOM after being tasked to assess the mechanics and practicality of the Gateway Experience.

It was not a CIA scientific finding that reality is a simulation. The CIA later held and released a copy through its declassified records. The U.S. Government Publishing Office now preserves the document as an Army publication.

Important distinction: this is an intelligence assessment proposing a theoretical model, not a replicated physics experiment and not proof that its metaphysical claims are true.

The model, in plain language

McDonnell's argument builds a staircase from ordinary physiology into increasingly speculative territory:

1 · Hemi-Sync. Different sounds presented to each ear create a perceived beat and are used to encourage particular mental states. 2 · Resonance. Deep relaxation, breathing, humming, attention and audio are described as helping the body and brain settle into a coherent pattern. 3 · Consciousness as energy. The report treats consciousness as an energetic pattern that can become increasingly coherent and focused. 4 · A holographic universe. Borrowing heavily from Itzhak Bentov and ideas associated with Karl Pribram, it imagines reality as an interference pattern in which information about the whole is distributed through the whole. 5 · The Absolute. Behind ordinary time and space, the report proposes an infinite, timeless field of consciousness it calls “the Absolute.” 6 · Altered-state access. Gateway's Focus states are presented as methods for perceiving information beyond normal sensory awareness, including claims about remote viewing, past/future perception and out-of-body experience.

The early steps overlap with real topics in psychology and auditory neuroscience. The later steps are philosophical and speculative. The report often moves from analogy to assertion much faster than modern scientific standards would permit.

The part that sounds like manifestation

One Gateway exercise discussed in the report is patterning. McDonnell describes it as forming a vivid mental model of a desired outcome while in an expanded state of awareness. His explanation goes further: he proposes that an intensely projected thought could become part of the “universal hologram” and influence how a person's reality develops.

This is probably the closest thing in the report to the internet claim that Gateway teaches you to “control the simulation.” The document really does make a consciousness-shapes-reality argument — but it presents that argument inside its own speculative holographic model, not as an established law of physics.

There is still a grounded version worth taking seriously: attention changes what we notice, repeated visualization can change behavior, expectations affect perception, and deliberate practice can alter habits. Those mechanisms alone can make an inner image surprisingly powerful without requiring reality itself to obey thought.

What is “the Absolute”?

McDonnell's “Absolute” is the metaphysical center of the paper: infinite consciousness outside ordinary time and space. Individual consciousness is described as a differentiated portion of that larger field, temporarily operating through physical reality and ultimately returning to it.

This is where the report stops sounding like a military memo and starts sounding like comparative mysticism. McDonnell explicitly compares his model with Eastern traditions, Jewish mystical ideas and Christianity.

Read spiritually, the striking idea is not “we live in a computer.” It is closer to: separate minds may be local expressions of a deeper field of consciousness, and altered states may change how much of that field we perceive.

That is a philosophical interpretation of the report, not a demonstrated scientific conclusion.

The famous missing page 25

It is real, but it is not a cheat code.

The CIA-released copy lacked one page. A complete version incorporating the missing page circulated publicly in 2021, with the recovered page attributed to a copy supplied by the Monroe Institute.

The recovered material continues the report's “Belief System Considerations.” It compares the holographic model with Tibetan Buddhist thought, Indra's net, Hebrew mysticism, the Christian Trinity and recurring spiral or torus imagery in religious traditions. It then moves into a section on the limits of strictly analytical, “left brain” thinking and the importance of self-knowledge.

That context is almost the opposite of the meme. Page 25 is less “here is how to control the Matrix” and more “modern physics and ancient mystics may be approaching some of the same intuitions through different cognitive styles.”

What the Army officer finally concluded

McDonnell concluded that there was, in his view, a rational basis for considering Gateway's essential objectives plausible. He recommended a phased program using Hemi-Sync, relaxation, hypnosis, out-of-body practice and the higher Focus states, while acknowledging problems such as information distortion.

That conclusion tells us what McDonnell believed after his assessment. It does not establish that remote viewing, out-of-body information gathering, future perception or the report's cosmology have been scientifically validated.

Where I think the interesting question really is

I do not need the Army's physics to be correct for the document to matter.

Human beings have been discovering ways to deliberately alter consciousness for thousands of years: prayer, chanting, breath, music, fasting, ritual, meditation, dance and sleep all change subjective experience. Gateway is a technological version of that old impulse — headphones, signal processing and a training protocol applied to the ancient project of exploring the mind.

Science can ask what the brain is doing. Spiritual practice can ask what the experience means. Neither question has to erase the other.

That is the part I want to carry forward: curiosity without gullibility, skepticism without closing the door, and enough humility to admit that consciousness remains one of the strangest things we know exists.
