Beyond Consciousness: How Meditators Voluntarily Enter Void States

Experienced meditators can voluntarily induce unconscious states, known as cessations, without the use of drugs. This ability, observed in Tibetan Buddhist practice, allows meditators to experience a momentary void of consciousness, followed by enhanced mental clarity.

Conducted across multiple countries, the study utilized EEG spectral analysis to objectively measure brain activity during these cessation events. By correlating the meditator’s first-person experience with neuroimaging data, researchers have gained insights into the profound modulation of consciousness achievable through advanced meditation practices.

Key Facts:

1. Experienced meditators can voluntarily enter a state of cessation, momentarily losing consciousness without external aids.
2. The study analyzed 37 cessation events in one expert meditator across 29 sessions using EEG spectral analysis.
3. This research opens new avenues for understanding consciousness modulation through meditation.

A study reveals that experienced meditators are able to voluntarily modulate their state of consciousness during meditation. In other words, they have the unusual ability, without the use of drugs, to induce a momentary void of consciousness during cessations through large-scale modulation of brain activity.

In what situations can a human being lose consciousness? An anesthetization, brain concussion, intoxication, epilepsy, seizure, or other fainting/syncopal episode caused by a lack of blood flow to the brain can cause total loss of consciousness. But can unconsciousness be induced without the use of drugs?

In the event known as cessation (or nirodha, according to Tibetan Buddhist terminology), the meditators briefly lose consciousness, but upon re-awakening, they are said to experience significant changes in the way their mind works, including a sudden sense of profound mental and perceptual clarity.

Matthew Sacchet, together with researchers from Australia, the Netherlands, and the United States, realized that the idea that a meditator has the ability to “turn off” consciousness could have broad implications for our understanding of how cognition works, but they also found that previous research on cessation had several limitations, namely the fact that few expert meditators have reached the level of meditation where cessations occur, and that cessations are also difficult to predict.

In the article “Investigation of advanced mindfulness meditation ‘cessation’ experiences using EEG spectral analysis in an intensively sampled case study,” published in November in the journal Neuropsychologia, the authors reveal that, in this intensive case study, they overcame these challenges by recruiting one expert meditator who reported being able to enter and report multiple cessation events as they emerged throughout repeated meditation sessions.

The researchers used a neurophenomenological approach in which the “first-person” descriptions of the cessations are related to objective neuroimaging data. In other words, the expert meditator systematically evaluated the mental and physiological processes (context, input, event, output, after-effects) as he experienced them, and these evaluations were used to group and select events for subsequent EEG-based analysis.

Spectral analysis of EEG data surrounding the participant’s 37 cessation events recorded in 29 sessions made it possible to relate the cessations to objective and intrinsic measures of brain activity related to consciousness and high-level psychological functioning.

According to researcher Matthew Sacchet, “these results provide initial evidence for the ability of adept meditators to voluntarily and profoundly modulate their state of consciousness and lay the foundations for further study of these unique states using neuroscientific and other empirical approaches”.
