    The Neuroscience of Meditation and Indigenous Storytelling

    Posted on April 27, 2026April 27, 2026

    From inward attention and self-regulation to shared meaning, memory, and relationship

    It is now widely accepted that Western neuroscience has something meaningful to offer the modern practice of meditation. By identifying neural correlates of attention, awareness, and emotional regulation, it has helped clarify mechanisms that practitioners have long described from within. What remains less clear is how this same lens might extend to other cultural practices, such as Indigenous storytelling. If meditation has been understood as a disciplined training of attention, storytelling may reveal a different but equally structured mode of mind, one that binds attention to memory, identity, and relationship. I am not Indigenous, but I offer these reflections with care, with the view that neuroscience can provide meaningful insight into aspects of this practice, even if it cannot fully account for it.

    With meditation, the science has largely focused on the regulation of attention and self. Studies often point to changes in the default mode network, the prefrontal cortex, and the insula. These correlate with reduced rumination, steadier focus, and heightened awareness of the body. The practice is often solitary, deliberate, and method-driven. The brain findings map neatly onto that structure.

    With Indigenous storytelling, the experience is less about directing attention inward and more about being drawn into a shared field of meaning. Neuroscience suggests several overlapping processes at work. When we listen deeply to a story, the brain enters a state of narrative absorption. Sensory and associative regions activate as if we are partially living the events. The usual analytic voice softens. This begins to resemble meditative immersion, though reached through story rather than breath.

    At the same time, storytelling strongly engages memory systems, especially those linked to identity. The hippocampus helps bind narrative to place, lineage, and personal meaning. Repetition deepens this encoding. What is being trained is not just attention, but belonging.

    There is also a social dimension that meditation research is only beginning to touch. In group storytelling, listeners’ brains can synchronize with each other and with the speaker. Rhythm, tone, and pacing entrain attention across the group. Emotion is co-regulated. The experience is not confined to one mind. It is distributed.

    Imagery and metaphor add another layer. Stories guide attention through images rather than instructions. The brain’s perceptual systems engage as if encountering the world directly. In this sense, storytelling becomes a way of training perception itself, shaping how reality is noticed and interpreted.

    So where meditation trains attention to stabilize and observe, storytelling may train attention to participate, remember, and relate. Neuroscience does not reduce one to the other, but it shows that both are structured ways of shaping mind and experience. One clarifies the mechanics of focus and awareness. The other reveals how identity, community, and world are carried and renewed through attentive listening.

    Seen this way, the contribution of neuroscience is not to explain storytelling away, but to quietly confirm that something real and trainable is happening there too.

    Training the Brain for a Lifetime

    Posted on March 14, 2026March 14, 2026

    What meditation research suggests about alpha, gamma, and long-term cognitive health

    Meditation research often searches for dramatic findings. Exotic states. Rare neurological signatures. Yet the most consistent observations are quieter and perhaps more consequential.

    Across many studies, regular meditation is associated with stronger alpha rhythms. The brain settles into a state of relaxed, attentive stability. In long-term practitioners another pattern sometimes appears: distinctive gamma synchrony, the fast oscillations linked with large-scale coordination across brain networks.

    These patterns appear often enough that they begin to look less like curiosities and more like markers of training. The nervous system seems to learn how to quiet internal noise while maintaining clarity, and how to coordinate widely separated regions of the brain with unusual precision.

    If sustained over years, such changes may reflect deeper biological effects. A brain operating with greater coherence may manage energy more efficiently, support mitochondrial function, encourage neuroplasticity and neurogenesis, and assist the brain’s own waste-clearing systems. These mechanisms are increasingly studied in relation to long-term cognitive health.

    The conclusions must remain measured. Meditation is not a cure-all, and research continues to evolve. But one implication is difficult to ignore.

    Just as the body benefits from lifelong physical exercise, the brain may benefit from lifelong training of attention. People who neglect cognitive health often experience decline earlier than they expect. Practices that stabilize and integrate the mind may help preserve clarity longer.

    Seen this way, meditation is not merely a method for occasional calm. It is a discipline that may support the long-term maintenance of the brain itself — a quiet investment in cognitive health over the course of a lifetime.

    The term, meditation, sticks

    Posted on February 25, 2026April 14, 2026

    I’m creating a new taxonomy for my meditation series and writing after years of careful study and analysis. I have no sentimentality, and am dropping long-favored terms like mindfulness and awakening. The basic term, meditation, however, denies change. I know it has too many meanings and uses, and is prey to misuse by charlatans, but it is still the best term for the modern practice I describe, grounded in traditional Buddhism, bolstered with neuroscience and neurotech, and creatively expressed with sound art. I think the term, meditation, sticks. I remain open to your thoughts.

    Meditation as Nervous System Training

    Posted on January 25, 2026January 25, 2026

    How attention, awareness, and repetition gradually reshape the mind

    Announcement

    The next Meditation Community series will be themed as the Neuroscience Edition. It will add a layer of neuroscientific explanation to traditional Buddhist meditation. The series will launch in autumn 2026.

    Meditation is not about emptying the mind or achieving special states. At a basic level, it is a way of gently training the nervous system. Modern neuroscience helps explain why this works.

    Attention is trainable
    Attention is supported by networks in the front of the brain that help us focus, choose, and inhibit impulses. Each time you notice your attention has wandered and bring it back, you are exercising these networks. This is not a mistake. The moment you notice distraction is the moment of training.

    The mind wanders by default
    When we are not deliberately focused, the brain naturally activates what is sometimes called the default mode network. This network supports self-talk, memory, and imagining the future. Meditation does not stop thinking. It changes our relationship to thought, so thoughts are seen more clearly and held more lightly.

    Emotion regulation comes from awareness
    Strong emotions are generated in older parts of the brain. Meditation does not suppress emotion. By staying present with sensation and feeling, without immediately reacting, the nervous system gradually learns that emotions can be experienced safely. Calm often appears as a side effect rather than a goal.

    The body is the gateway
    Breath, posture, and bodily awareness influence the nervous system directly. Slow breathing and grounded posture support stability and recovery. Returning attention to physical sensation is one of the most reliable ways to steady the mind.

    Repetition matters
    From a brain perspective, meditation is training. Short, regular practice produces more lasting change than occasional intense experiences. Consistency matters more than depth.

    In simple terms
    Meditation trains us to notice without immediately reacting, steady attention, regulate emotion through awareness, and inhabit the body more fully. It is the slow education of a living nervous system.

    Peer-Led Meditation

    Posted on January 13, 2026January 13, 2026

    On facilitation, letting go, and sitting together

    When I started a meditation group at my workplace in 2019, I suggested to my two colleagues that it be “peer-led.” What I meant at the time was that I did not especially know much about guiding meditations, and their quick embrace of the idea suggested they did not either.

    It turns out it is not hard to guide a meditation. Sit, relax, breathe, meditate in silence for a while, thanks for coming. Of course, there are many kinds of meditation. As our meditation group caught on, hundreds of people have attended, many of whom shared their own meditation knowledge, from music and visualization to yoga nidra and vipassana. I believe it was the peer-led quality of our organization that made so many people feel welcome, not only to join us but to share what they knew.

    Meditation has not always been associated with this kind of peer-led or decentralized organizational structure. For much of its history, it has been transmitted through formal lineages, hierarchical institutions, and clearly defined teacher–student relationships. Authority was conferred by training, ordination, or proximity to a tradition, and the role of the teacher was to preserve and pass on a specific form with fidelity. Access to meditation often depended on geography, culture, language, and permission. In that context, meditation was not something one casually offered to others, but something one received carefully from someone authorized to give it.

    In the meditation community in which I participated at work for the past seven years, and continue to participate, being peer-led was always treated as an essential quality. I understand now that this was not incidental. It may, in fact, have been the defining quality of the community itself.

    That quality expressed itself in many ways. While a small number of people led most meditations, myself included, this is true of most volunteer organizations, and for familiar reasons. Still, there was always room for movement, and movement did happen. At different times, I and other active leaders were away from work for various reasons, and others stepped in, changing how things ran, along with the style and tone of the group.

    Being peer-led also meant that sometimes nothing happened at all. No one signed up to guide a meditation. People showed up and improvised, or simply drifted away. At times it seemed as though everyone had lost interest and the group might fold. More often, it turned out to be just ebb and flow. With the turn of a season, the group would surge back into life again.

    I intend this peer-led quality to guide more explicitly the design of this public meditation community, something like the prime directive of Star Trek. While there is a program design, I invite anyone who is interested to guide a meditation. Whether it fits a designated topic or not, we will make it work. Future phases of the program will offer opportunities for participants to join design sessions, as we explore research and artistic applications of meditation. Finally, while this community operates on my digital platform, I think of it as an open-source model, available to be branched should someone wish to start their own meditation community. I would assist and support this.

    One last thing. I mentioned in the last sitting that, despite my best efforts, there may be an occasion when my power is out, my phone is down, and I cannot join a scheduled meditation. In that case, I invite anyone who is able to take the lead and guide a meditation. Perhaps only to say: sit, relax, breathe, meditate in silence for a while, thanks for coming. Such is the way of a peer-led meditation group.

    The wisdom of meditation is death

    Posted on December 23, 2025April 14, 2026

    The wisdom of meditation is death.
    Sorry not sorry.

    Death teaches that everything changes and nothing lasts,
    that suffering comes from clinging, chasing, and avoidance.

    Even if I accept the end of body and ego,
    I do not personally own an everlasting soul.

    Knowing this on my deathbed is inevitable.
    Knowing it while I still live is wisdom.

    Three ways of being

    Posted on December 22, 2025April 14, 2026

    Three ways of being:

    1. Rolling anxiety
    2. Chasing cravings or goals, with brief interludes of satisfaction
    3. Practicing meditation, with increasing stretches of stillness and bliss

    Cold Water Immersion is a Masterclass in Meditation

    Posted on December 4, 2025December 4, 2025

    Shinto turns to cold squatting beneath freezing waterfalls in winter, standing in icy springs, or repeatedly dousing the body with frigid water — I prefer a winter river

    Shinzen Young tells of his training in the shamanic tradition of Shinto, Japan’s pre-Buddhist tribal religion. Many tribal cultures seek visions of gods or spirits through prolonged exposure to extremes. In India, some Hindus practise the “five fires.” In North America, certain Indigenous traditions use the sweat lodge and the sun dance. These lean toward heat. Shinto goes in the other direction. It turns to cold squatting beneath freezing waterfalls in winter, standing in icy springs, or repeatedly dousing the body with frigid water.

    For Shinzen, this meant approaching a cistern filled with half-frozen water, breaking the ice crust, filling a huge wooden bucket, and then squatting as he dumped the bone-chilling liquid over his bare skin. The water froze as it hit the floor. His towel froze in his hand. He slid around barefoot on the ice, trying to dry himself with a towel that had turned to a board. It was, for him, a horrific ordeal. He suspected that being a thin-skinned Californian did not help.

    I prefer a winter river. There are always three stages. First, my mind tells me not to do it. It warns me that this is a threat to my life. I quiet the mind. Second, as I descend past my waist, I begin to hyperventilate. My body triggers its survival response, drawing blood toward the core. It lasts only seconds. Third, I adapt. After a minute, the cold becomes neutral, even spacious. I stay in for up to five minutes.

    Beginners enter and exit quickly. They cannot silence the mind or allow the body to adapt. They fear death. Experienced practitioners settle into calm. They release the mind’s grip and the fear that shadows it. Immersed in the river, the sense of body and ego separation dissolves. They feel connected with everything. Samadhi.

    Cold water immersion is a masterclass in meditation. In one minute, it teaches you to quiet the mind’s cry for comfort, a skill that carries into every hard thing in life. Or you could spend a lifetime sitting on a pillow. No doubt there are lessons in both practices.

    Could some future technology take a deposit of these thoughts?

    Posted on November 27, 2025April 14, 2026

    A wave, the Buddhists say. Not a soul, just movement.
    Parfit calls it a bundle: thoughts, memories, sensations, intentions —
    held together by continuity rather than ownership.

    A binding
    meant to come undone at death.

    But how does that binding last a lifetime?
    Is the body such a strong tether,
    carrying the same feeling of “me” for so many years?

    Could some future technology
    take a deposit of these thoughts, memories, sensations, intentions
    and let the wave continue — not as possession,
    but as momentum — a kind of reincarnation after all?

    Or is the familiarity my mistake?
    Is the wave remade each moment,
    the binding refreshed so quickly
    that I can’t see the breaks?
