Project MK‑Ultra, launched in 1953 under the direction of Allen Dulles and chemist Sidney Gottlieb, sought to manipulate human behavior using drugs, hypnosis, sensory deprivation, and more (whyy.org, en.wikipedia.org). While LSD and chemical interrogation are the most infamous elements of the program, MK‑Ultra encompassed over 150 subprojects—one of which included methods such as biofeedback, meditation, and controlled breathing (hks.harvard.edu).
These techniques—though less sensational than LSD—were used to train subjects to control physiological functions like heart rate and breathing. By inducing altered states through guided respiration, the CIA hoped to gain entry into deeper layers of the subconscious, potentially facilitating interrogation or memory erasure.
The Gateway Process.
Breathing as a Mind-Control Tool
A key declassified file, the CIA’s “Analysis and Assessment of Gateway Process”, documents how hypnosis, transcendental meditation, biofeedback, and intentional breathing were intertwined (cia.gov). The report describes slow, deep breathing patterns synchronized with mental imagery to shift subjects into trance-like states.
These sessions emphasized:
Slow, rhythmic inhalation and exhalation to slow brainwaves from beta (alert) into alpha/theta (relaxed).
Biofeedback, where participants monitored physiological signals (like heart rate variability) to learn control over stress responses.
Hypnosis overlays, inducing a relaxed state to facilitate suggestion or memory manipulation.
Transcendental Meditation and “Hemi-Sync” Techniques, The Gateway report also mentions meditation—specifically transcendental meditation (TM)—as a method for reaching deep consciousness.
Emotional Conditioning and Memory Loading, The final piece was how these techniques could be used to load emotional content or suggestive patterns into the subconscious.
The report theorized that these techniques could “load” certain patterns into the subconscious, effectively altering emotional or behavioral responses.
Let’s explore the techniques outlined in the CIA’s declassified “Analysis and Assessment of Gateway Process” report in more detail, particularly focusing on how breathing was used in tandem with other mind-altering methods like hypnosis, biofeedback, and transcendental meditation.
1. Slow, Rhythmic Breathing and Brainwave Manipulation
At the heart of the Gateway Process was the idea that slow, controlled breathing could shift the brain’s state from everyday consciousness (beta waves) into deeper, more suggestible and relaxed states (alpha and theta waves). Here’s how that worked:
Breathing deeply and slowly—inhaling for about 4–6 seconds, holding briefly, and exhaling for 6–8 seconds—activates the parasympathetic nervous system. This system is responsible for the “rest and digest” state, countering stress and inducing calm.
When practiced consistently, this type of breathing can synchronize with brain activity, encouraging the brain to produce more alpha waves, which are associated with relaxation and creativity, and theta waves, which are linked to deep meditation, intuition, and trance-like states.
In the context of MK Ultra and the Gateway Process, breathing wasn’t just about calming the subject—it was a gateway into deeper cognitive layers where subconscious material could be accessed or manipulated.
2. Biofeedback and Physiological Awareness
Biofeedback was another key component used to help subjects gain control over their involuntary body functions, such as heart rate, body temperature, and even brainwave patterns.
Through the use of monitors and sensors, subjects were shown real-time data about their own physiological states.
With practice, subjects could learn to consciously change their heart rate or brainwave patterns by adjusting their breathing, posture, or thoughts.
In some sessions, they would be asked to breathe slower or deeper while watching their brainwave monitor, and were rewarded (sometimes with pleasant sounds or sensations) when they reached certain desired states like deep relaxation or heightened focus.
This process turned breathing from a passive activity into an interactive tool for psychological control—a way for the subject (or experimenter) to deliberately enter altered states.
3. Hypnosis and Breathing as Induction Tools
Hypnosis was frequently layered over these breathing exercises. It was used to take advantage of the altered state induced by slow breathing and biofeedback control. The Gateway report explains that:
Once a person had entered a relaxed alpha/theta brain state through breathing and biofeedback, they were highly susceptible to hypnotic suggestion.
Hypnotists would use breathing patterns themselves—speaking slowly, rhythmically, and instructing the subject to breathe in sync with their voice—to deepen the trance.
In this deeply relaxed state, memories could be manipulated, false ones implanted, or behaviors altered through subtle suggestion.
Some sessions reportedly combined hallucinogenic drugs (like LSD or mescaline), making the subject even more pliable, while breathing exercises helped manage anxiety or physical side effects. The goal was to reprogram the subconscious using a cocktail of techniques.
4. Transcendental Meditation and “Hemi-Sync” Techniques
The Gateway report also mentions meditation—specifically transcendental meditation (TM)—as a method for reaching deep consciousness.
TM involves mantra repetition, which serves as a mental anchor similar to the breath.
Combined with intentional breathing, this could induce a float-like detachment, where the subject felt separated from their body—sometimes interpreted as “out-of-body experiences.”
The CIA report ties this directly into their interest in Hemi-Sync, a system that used binaural beats and breathwork to synchronize the left and right brain hemispheres, supposedly allowing access to “higher states of awareness.”
This was not just about relaxation or therapy—it was about pushing the boundaries of consciousness to explore whether individuals could access extrasensory perception, remote viewing, or cognitive reprogramming.
5. Emotional Conditioning and Memory Loading
The final piece was how these techniques could be used to load emotional content or suggestive patterns into the subconscious.
By entering a trance state through breathing, meditation, and hypnosis, subjects became highly impressionable.
In this state, researchers could introduce specific thoughts, fears, or memories, whether real or imagined.
Over time, this could alter how a person emotionally responds to certain stimuli. For example, someone could be conditioned to feel fear when seeing a particular symbol or experience calm when exposed to a certain phrase.
The CIA believed that this combination—breathwork, feedback control, and hypnotic programming—could create mental imprints strong enough to change behavior long after the session ended.
The Gateway Process wasn’t just about breathing—it was about using the breath as a tool to unlock the deeper mechanisms of the mind. The slow, rhythmic breathing was the key that opened the door. Once inside, agents could use hypnosis, suggestion, and biofeedback to restructure perception, emotion, and potentially even reality itself.
While modern science might question the full extent of these claims, the fact that such techniques were explored by the CIA highlights how powerful breath and consciousness control were considered in both psychological warfare and mind enhancement strategies.
Breathing in the Field.
Practical and Ethical Concerns
Breathing techniques joined other brutal methods. While LSD dosing was often covert—famously in the “Midnight Climax” safehouses—breathing and meditation were less overtly invasive but still manipulative (cia.gov, wired.com, history.com). In some safehouses, subjects were unaware they were being guided through breathing exercises to lower their defenses and encourage suggestion acceptance.
Breath control, theoretically benign on the surface, was thus weaponized to induce psychological compliance without physical trauma. Unlike psychedelics, breathing techniques left no chemical trace, yet could produce profound shifts in cognition when combined with guided imagery and post‑hypnotic suggestion.
Forgotten Roots.
From Psychiatry to Interrogation
The CIA’s interest in breathing methods had academic roots. Psychiatric institutions like McGill’s Allan Memorial Institute, linked to Dr. Donald Ewen Cameron, used a mix of drugs, hypnosis, sleep, and sensory deprivation—often alongside breathing control—to erase or “re‑program” mental pathways (en.wikipedia.org).
Although Breathing-centric subprojects received less attention, they represented MK‑Ultra’s broader ambition: control minds through multiple entry points—chemical, physical, psychological—even with minimal awareness.
Life After MK‑Ultra.
Legacy and Modern Parallels
After the Church Committee and Rockefeller Commission hearings of 1977, the CIA officially ended MK‑Ultra, but many declassified docs suggest continued interest in mind‑control methods (en.wikipedia.org).
Today, breathing exercises remain widely respected for mental wellness and performance. Ironically, similar techniques are taught in elite circles—athletics, military—far from clandestine labs. The difference lies in consent. MK‑Ultra used breathing as a covert behavioral lever, raising deep ethical questions the modern wellness community still grapples with.
A Cautionary Tale.
Ethical Boundaries
The Gateway Report demonstrates that even techniques perceived as innocuous—like breathwork and meditation—can be exploited. Power lies not only in chemical coercion but in harnessing self-regulation tools without disclosure. MK‑Ultra illustrates the extreme ends of such manipulation: what begins as therapy can pivot into control under the wrong intent.
As these methods return to mainstream—yoga, mindfulness, biofeedback—MK‑Ultra reminds us of a vital principle: informed consent and transparency are non-negotiable.
Closing Reflections
MK‑Ultra’s legacy is twofold: a dark chapter of non-consensual human experimentation—and a lesson on the latent power of simple techniques. Breathing, biofeedback, and hypnosis are not inherently sinister—but in MK‑Ultra’s hands, these tools became instruments of control.
The recently released CIA files—Gateway Process and Senate hearing records—provide an unsettling window into how watchers can weaponize calmness itself . Our responsibility now is to remember: these practices must be ethically framed, consensual, and transparent. Otherwise, we risk repeating a covert abuse masked as wellness.
Interestingly as soon as I first downloaded this after writing, all my work was lost. Happy hunting.
The breath is sacred. In MK‑Ultra, it became suspect.
May that knowledge keep our use of these tools noble.
