When an Ancient Human Expression Meets Modern Consciousness Research
Light language is becoming increasingly visible within meditation, energy work and consciousness communities. To those who experience it, it may arise as unfamiliar syllables, tones, singing, sounds, hand movements or even written symbols. There may be no intellectual understanding of what is being expressed, yet the experience can feel deeply intuitive, emotional or meaningful.
What makes this especially interesting today is that the Institute of Noetic Sciences (IONS) has begun formally studying the phenomenon.
For something that has largely lived within personal spiritual experience, this is an exciting development. It creates a bridge between lived experience, consciousness and scientific curiosity.
Is Light Language Really New?
The name light language is relatively modern, but spontaneous non-ordinary vocalisation is certainly not new.
One of the best-documented historical parallels is glossolalia, commonly called “speaking in tongues.” References to this form of spontaneous vocal expression appear in early Christian writings associated with Paul nearly 2,000 years ago. Researchers have subsequently studied glossolalia from linguistic, psychological, neurological and religious perspectives.
Contemporary light language has developed within a different context. Instead of being understood specifically as an expression of the Holy Spirit, practitioners may describe it as intuitive communication, energetic expression, soul language, vibrational information or communication arising through expanded states of consciousness.
An anthropological account published by Harvard’s Center for the Study of World Religions describes contemporary practitioners who understand light language as a spontaneous or channeled expression that communicates through vibration and felt experience rather than ordinary linguistic meaning. These are descriptions of practitioners’ experiences and beliefs rather than scientific conclusions about what the sounds objectively contain.

And this distinction is important.
We can remain open to the meaning of an experience while also remaining curious about how that experience occurs.
IONS Is Now Studying Light Language
In January 2026, the Institute of Noetic Sciences (IONS) announced its Light Language ~ Non-Religious Glossolalia Study.
IONS describes light language as unknown utterances, speech or sound patterns that can emerge during experiences such as meditation, prayer, trance or altered states of consciousness.
What makes the study particularly interesting is its focus on non-religious glossolalia.
While speaking in tongues within religious settings has been studied for decades, IONS notes that similar experiences occurring outside organised religion have received very little scientific attention. Their research is therefore attempting to systematically understand the people having these experiences and what happens when light language arises.
The researchers are exploring questions such as:
- How did a person’s experience of light language first begin?
- Under what conditions does it emerge?
- Is it associated with meditation or altered states of consciousness?
- What does the person experience internally while it is happening?
- Does the speaker feel they understand or interpret what is being expressed?
- Are there common psychological, personality, mindfulness or mystical-experience characteristics among people who experience it?
The study begins with an online survey covering areas including mindfulness, absorption, personality, mystical experiences, consciousness and participants’ experiences of light language. Participants are then invited to a recorded interview where researchers explore their experiences in greater depth. The investigators are IONS Director of Research Helané Wahbeh and Siri Zemel.
What I appreciate about this approach is that science does not have to begin by saying whether an experience is real or unreal.
It can begin with curiosity:
What is happening here?
What is the person experiencing?
Are there common patterns?
And what can this teach us about human consciousness?
What Does Neuroscience Already Know?
Light language itself is still largely unexplored scientifically, but researchers have previously examined the related phenomenon of religious glossolalia.
One neuroimaging study found changes in brain activity while participants engaged in glossolalia compared with religious singing, including reduced activity in areas of the prefrontal cortex. Researchers interpreted this in relation to participants’ subjective experience that the vocalisation felt less consciously directed or intentionally controlled.
Another study involving 30 experienced glossolalia practitioners found associations between the amount of practice and structural differences in frontal brain regions involved in higher-level cognitive processes. The researchers suggested that extensive practice may involve a degree of neurocognitive specialisation.
These studies tell us something fascinating:
An experience that appears unusual from the outside can still correspond with measurable changes in how the brain functions and adapts.
And that opens a much richer conversation.
Light Language and Healing
Many people who receive or express light language describe relaxation, emotional release, peace, connection, bodily sensations, imagery or a shift in awareness.
There may eventually be several layers through which we understand these experiences.
The spiritual perspective may speak about vibration, resonance, energy and consciousness.
The psychological perspective may explore emotional expression, surrender, meaning and altered states.
Neuroscience may investigate attention, vocalisation, brain activity, autonomic regulation and states in which conscious verbal control becomes quieter.
These perspectives do not necessarily have to compete with one another.
They may simply be looking at different dimensions of the same human experience.
Staying Open Without Losing Discernment
One of the most beautiful developments in consciousness research is our growing willingness to explore experiences that previous generations might have immediately labelled, dismissed or placed entirely within religion.
The IONS study is still research in progress.
And yet, absence of an answer is also an invitation to inquiry,
