What did the declassified documents reveal?

The document before us is a June ninth, nineteen‑eighty‑three assessment titled “Analysis and Assessment of Gateway Process,” prepared for the United States Army Operational Group at Fort Meade, Maryland, by the United States Army Intelligence and Security Command. It is notable because it records a formal military evaluation of the Monroe Institute’s “Gateway Experience,” a program that sought to induce altered states of consciousness through brain‑hemisphere synchronization. The material was released to the public through The Black Vault archive, where it appears as a digitized text file. The release is attributed to a declassification request filed under the Freedom of Information Act, with the agency’s declassification authority authorizing public access. The full document can be accessed at the Black Vault URL https://archive.org/download/cia-gateway/6-full-reportdjvu.txt. The document reads as follows. “DEPARTMENT OF THE ARMY U.S. ARMY OPERATIONAL GROUP U.S. ARMY INTELLIGENCE AND SECURITY COMMAND FORT GEORGE G. MEADE, MARYLAND 20755 AGPC‑9 June ninth, nineteen‑eighty‑three SUBJECT: Analysis and Assessment of Gateway Process TO: Commander, U.S. Army Operational Group, Fort Meade, Maryland 1. You tasked me to provide an assessment of the Gateway Experience in terms of its mechanics and ultimate practicality. As I set out to fulfill that tasking it soon became clear that in order to assess the validity and practicality of the process I needed to do enough supporting research and analysis to fully understand how and why the process works. Frankly, Sir, that proved to be an extremely involved and difficult business. Initially, based on conversations with a physician who took the Gateway training with me, I had recourse to the biomedical models developed by Itzhak Bentov to obtain information concerning the physical aspects of the process. Then I found it necessary to delve into various sources for information concerning quantum mechanics in order to be able to describe the nature and functioning of human consciousness. I had to be able to construct a scientifically valid and reasonably lucid model of how consciousness functions under the influence of the brain‑hemisphere synchronization technique employed by Gateway. Once this was done, the next step involved recourse to theoretical physics in order to explain the character of the time‑space dimension and the means by which expanded human consciousness transcends it in achieving Gateway’s objectives. Finally, I again found it necessary to use physics to bring the whole phenomenon of out‑of‑body states into the language of physical science to remove the stigma of its occult connotations, and put it in a frame of reference suited to objective assessment. 2. I began the narrative by briefly profiling the fundamental biomedical factors affecting such related techniques as hypnosis, biofeedback and transcendental meditation so that their objectives and mode of functioning could be compared in the…
