The Neurology of Being

What does it actually mean to be? In clinical practice and daily life, we often speak about the need to “just be” or to “stop doing so much”—but the state of being is rarely defined in physiological terms. Is it rest? Is it stillness? Is it the absence of threat?

For many patients, being isn’t a familiar or accessible state. It may feel foreign, uncomfortable, or even dangerous. This is especially true for those with histories of chronic stress, survival-based patterning, or developmental trauma. In these systems, “being” is not simply the opposite of “doing”—it is an autonomic state the body has forgotten how to enter.

To re-access it, we must first understand what “being” is in terms of neural activation, channel function, and fascial tone. This section outlines the key features of the being state—both in the nervous system and in the somatic channel structure—and contrasts them with the mobilized architecture of doing.

Classical Reflections on Being

The question of being—what it is, where it resides, and how it becomes obscured—has been asked long before the language of nervous systems or channel theory existed. In ancient philosophy, the body and mind were often thought to be at odds, or at best, joined by a fragile thread. Descartes' “I think, therefore I am” reduced existence to cognition, placing identity in the domain of the rational mind. But clinical reality suggests the opposite: many of us think constantly and still struggle to feel that we are.

In Eastern traditions, particularly Zen, the instruction to “just sit” or “just be” is offered as a return to essential presence. Yet for many patients—and for many practitioners—that invitation can feel more like a confrontation. Stillness reveals the very thing the nervous system has spent a lifetime learning to avoid. Muscles clench. Thoughts loop. The breath flattens. Not because the instruction is wrong, but because the parasympathetic (yin) infrastructure to receive it is missing.

Even Socrates’ “Know thyself” invites us into an inner world, but often bypasses the medium through which we know: the body. Self-awareness is not a merely mental act. It is also a somatic-visceral one, shaped by how the viscera respond, how the spine organizes, and how the breath yields—or doesn’t. In other words, before we know ourselves, we are shaped to exist. And if that shaping carries disruption—early bracing, chronic vigilance, unresolved orienting patterns—then the very experience of being can feel incomplete, or unreachable.

This is where Chinese medicine becomes not only relevant but essential. The secondary channels of postnatal development—the Qiao and Wei sinew channels—form in tandem with the limbic system, autonomic circuits, and primitive motor networks. Because of this shared developmental timing, they carry more than structural tone—they hold emotional charge. They govern how tension is distributed through the limbs and trunk, how the body maintains orientation under stress, and where fascial bracing or armor is laid down in response to perceived threat or demand. These patterns do not resolve on their own. They persist long after the original stimulus has passed and continue to shape how the body responds to safety, pressure, and contact.

The sinew channels of the Eight Extraordinary Vessels do not just reflect emotional states—they help encode them. Vigilance, withdrawal, or urgency becomes embedded in the body’s movement and posture, shaping fascial tone, breath patterns, and autonomic set-points. These are not metaphors. They form a living map of where the system remains braced for impact—an internal architecture through which unresolved readiness continues to operate in the background, gradually depleting yin and eroding jing. Over time, this somatic patterning drives cortical overactivity—especially in regions responsible for evaluation, decision-making, and self-monitoring—while cortisol suppresses gut motility, vagal tone, and immune function. When prolonged, this is the physiological basis of what TCM calls “phlegm misting the mind”: a condition in which fascial rigidity, sympathetic override, and enteric disruption block access to reflective awareness. The sinews provide direct entry points for treatment, making cortical quieting and the experience of mindful presence physiologically possible.

Definition: “Being” (Within a Neuro-Somatic and Channel-Based Framework)

Being is the baseline state of non-reactive presence in which the body is not mobilizing toward action, not suppressing internal sensation, and not orienting toward external threat.

In this state:

  • The autonomic tone is primarily ventral vagal (parasympathetic), not sympathetic or dorsal-collapse
  • The motor system is in neutral—no anticipatory tension, no prepulse toward movement
  • The interoceptive system is accessible—signals from viscera, diaphragm, heart, and gut can be felt without distortion
  • The cortical system is not driving evaluative control—especially mPFC, anterior cingulate, and insular hyperactivity is quieted
  • The midline fascial structures are tonally receptive—not held, not collapsed

I. Neurological Markers of “Being”

System

State in “Being”

Autonomic

Ventral vagal dominant; sympathetic tone low, dorsal vagal not dominant

Motor planning (cortex)

Quiet SMA and dACC activity; no active goal-setting or movement prep

Insular cortex

Open interoceptive registration without urgency

Amygdala–hippocampus

Not signaling threat; internal environment interpreted as safe

PAG / brainstem nuclei

No freezing or flight-readiness signaling

DMN / limbic-cortical loop

Present-moment continuity, minimal narrative projection


II. Somatic and Channel-Based Correlates of “Being”

  • Ren Mai (Conception Vessel): supports internal coherence, parasympathetic tone, nourishment
  • Yin Qiao: flexor tone without reactivity, capacity to be inwardly oriented without collapse
  • Yin Wei: emotional congruence, containment of internal states without cortical override
  • Deep midline stabilizers (multifidus, diaphragm, psoas): support verticality and inner space without effort

Together, these create a structural state where:

  • The body feels safe to exist without doing
  • Internal sensation is not flagged as urgent
  • There is no perceived need to leave or suppress the present moment

II. Somatic and Channel-Based Correlates of “Being”

When the body is in a state of being, certain tissues and channel systems function in specific, observable ways. These aren’t vague energetic metaphors—they reflect how the body is actually organizing itself in space and time.

Ren Mai (Conception Vessel):

  • This channel supports the midline of the body—from the pelvis to the face—and is associated with the parasympathetic nervous system, especially vagal tone.  Think nourishment, both systemically from the Enteric Nervous System (post-natal qi), and locally in the microcapillary beds in the from of oxygen exchange. 
  • In a state of being, the Ren is responsive but not guarded or diminished by the Du mai (internal rotators and multifidus). There’s a sense of open front body tone—the belly is not clenched through Ren 15-Liv13-ST 25-GB 25, the breath can descend into the abdomen, and the throat is not braced. (Ren-Chong Intersection via the spiral line).
  • The core of the body feels intact and continuous, not armored, braced or collapsed.

In plain terms:

The person can rest in their own verticality. They don’t feel exposed in the chest or hollow in the belly. They are not gripping themselves for structure.


Yin Qiao Mai (Yin Motility Vessel):

  • This channel runs through the inner legs, pelvis, and abdomen, and governs flexor tone—the capacity to bring the body inward.
  • In a healthy state of being, the inner thighs, pelvic floor, and deep abdominal wall are softly engaged—not locked, not flaccid.
  • There is a sense of inward support—the body doesn’t need to lift up out of itself or collapse down through the hips.

In plain terms:

The person doesn’t feel like they’re “falling in” or needing to brace to stay upright. There’s a quiet tone holding the base of the torso, so they can sit or lie still without restlessness or dissociation.


Yin Wei Mai (Yin Linking Vessel):

  • This channel connects deep internal tissues of the chest and abdomen, and is linked to emotional containment and internal coherence.
  • When this system is working well, the heart, diaphragm, and gut can remain responsive without being hijacked by threat signals or over-monitoring from the brain. (HPA Axis and chronic cortisol)
  • The person can feel emotion or sensation without needing to interpret it, explain it, or suppress it.  For our neuroscientists, this is containment of internal states without cortical override. For PVT enthusiasts, we could consider this remaining in an undefended ventral vagus state. 

In plain terms:  The body can have feelings without immediately trying to fix, understand, or shut them down. There’s room for affect to move through without losing orientation.


Du Mai (Governing Vessel)  

·         Midline Core Stabilizers (Multifidus, Diaphragm, Psoas): These are the deep muscles that stabilize the spine and help maintain posture without effort.  Patients with spasticity and rigidity in the fascia here are often in reflex demonstration.

  • In a true state of being, these muscles are tonically active at a low level—they hold the skeleton upright without needing to recruit the large, external muscles of the back, neck, or shoulders.
  • The breath moves through the diaphragm with ease, and the psoas responds to gravity without tension or slack.

In plain terms:  The person doesn’t have to “sit up straight” or hold themselves together. The spine organizes itself. The breath lands. The head feels like it’s supported from below, not suspended by the neck.


Together, these create a structural state where:

  • The body feels safe to exist without doing
  • Internal sensation is not flagged as urgent
  • There is no perceived need to leave or suppress the present moment

 Definition: “Doing” (Within a Neuro-Somatic and Channel-Based Framework) Somatic and Channel-Based Correlates of Doing  (Yang-Side Expression)

 Doing is a state of mobilized orientation in which the body prepares for or engages in action—externally or internally. It is characterized by anticipatory structure, directional output, and heightened regulatory control. This state may be adaptive (task engagement) or maladaptive (chronic readiness without resolution).

In this state:

  • The autonomic tone is sympathetic-dominant or blended with low vagal tone; physiological systems are tuned for action readiness (↑ heart rate, ↑ vigilance, ↓ digestive function)
  • The motor system is biased toward goal orientation—preparatory activity in motor planning regions (SMA, dACC); even when still, there is often low-level flexor or extensor recruitment
  • The interoceptive system is filtered or overridden; bodily sensation is often minimized, distorted, or registered only in relation to threat, urgency, or goal demands
  • The cortical system is task-focused—especially dlPFC, dACC, and premotor cortex directing attention, inhibition, and planning; mPFC self-reference is diminished or performance-based
  • The fascial system is tonically braced or organized around projection—especially through the posterior (Du), lateral (Yang Wei), or superficial extensor chains

 

 

I.  Neurological Markers of “Doing” (Yang-Dominant State)

System

State in “Doing”

Autonomic

Sympathetic dominant; increased norepinephrine release, reduced vagal tone

Motor planning (cortex)

Heightened SMA and dACC activation; motor programs primed, goal-seeking circuits engaged

Insular cortex

Interoception is filtered for urgency or external relevance; diminished internal felt sense

Amygdala–hippocampus

Amygdala actively monitoring threat or salience; hippocampal loops primed for environmental mapping

PAG / brainstem nuclei

Periaqueductal gray engaged in action-readiness modulation; brainstem arousal systems (LC, RF) activated

DMN / limbic-cortical loop

Default mode suppressed; medial PFC disengaged from self-reflection, task-positive networks dominate


This state aligns with the chronic action-preparedness we’ve been exploring—where the body and brain are continuously organized for interaction, output, or defense, often long after the initiating stimulus has passed.

Let me know if you'd like a side-by-side version with the Being table for reference or inclusion in teaching materials.


Du Mai (Governing Vessel):

  • The Du Mai runs along the spine and governs Yang activation, motor planning, and outward expression.
  • In a doing state, the Du tone is elevated, meaning there’s increased tonic drive through the paraspinal muscles, back of the neck, and occipital base.
  • This creates a kind of "internal exoskeleton"—the body braces along its spine to stabilize against potential action or collapse.

In plain terms: The person may feel like they’re holding themselves up from behind—tight in the back, jaw set, tongue pushing upward. Even if they’re still, their back body is ready to spring.


Yang Qiao Mai (Yang Motility Vessel):

  • This channel regulates extensor tone and outward propulsion, especially through the lateral leg line, posterior pelvis, sacrum, and occiput.
  • In a heightened doing state, Yang Qiao increases drive through the glutes, lower back, and posterior chain—preparing for movement or alertness.
  • This often creates tension in the sacroiliac area, hamstrings, calves, and occipital ridge—places where extension is chronically "on."

In plain terms: The person may feel like they’re always subtly “leaning forward,” even when standing still. There’s a micro-torque in the spine, a push through the feet, and a tension across the back of the head—as if they’re bracing against gravity or expectation.


Yang Wei Mai (Yang Linking Vessel):

  • The Yang Wei system links the Yang channels of the limbs and torso, regulating the body’s relationship to external time, pressure, and environmental rhythm.
  • In doing mode, Yang Wei governs the body's sense of timing, pacing, urgency, and internal clocking.
  • When overactive or prolonged, it creates a felt pressure to keep up, stay ahead, anticipate what’s coming.

In plain terms: The person may feel like time is pressing in on them. Even if nothing urgent is happening, there’s a sense of being slightly late, not quite ready, or on the verge of needing to act. Their body is organized around “what’s next?” rather than “what is.”


Superficial Back Line & Global Extensors:

  • The superficial fascial line that includes the erector spinae, glutes, hamstrings, calves, and plantar fascia becomes dominant in prolonged Yang states.
  • These muscles shift from responsive postural tone to sustained contraction, often without awareness.
  • The result is a system that feels prepared, upright, alert—but rigid and fatigued underneath.

In plain terms:  The person is “on,” even when they don’t want to be. Their back is tight. Their legs don’t rest fully into the ground. There’s a sense that they must stay vertical, stay efficient, stay in motion—or something will fall apart.

 

Together, these Yang-side systems organize the body around doing: maintaining readiness, asserting control, projecting forward. When balanced with Yin, they support action. But when running alone, or in the absence of rest, they produce restlessness, bracing, vigilance, and fatigue—a state of doing without grounding.


The Essential Conflict: Do-Be-Do-Be-Do

The conflict between doing and being is not just philosophical; it is structural and neurosomatic. It lives in the interaction between the Ren Mai and the Du Mai, between the parasympathetic drive to nourish and restore and the sympathetic imperative to act, to stabilize, to survive. These two systems are not antagonists; they are interdependent partners. But in bodies shaped by prolonged stress or threat, the exchange collapses into hierarchy. Doing overrides being. Readiness becomes the baseline. Rest becomes unfamiliar, or even intolerable.

The Ren Mai represents more than parasympathetic tone. It supports our capacity to receive breath, to coordinate the diaphragms, to activate digestive motility, and to access autonomic tone through ventral vagal engagement. It governs the midline and visceral field, supporting interoception—the capacity to sense one’s own internal organs and body state. When this system is intact, the body can soften and integrate emotional experience.

This conflict is mirrored through the entire axial structure. Below the neck, it appears in the deep spinal stabilizers: the rotatores, multifidus, psoas, and diaphragmatic layers that hold the central column. When the body is safe, these muscles soften. When the body is threatened, they grip. Above the neck, the same tension registers in the brainstem and midbrain as orientation, motor planning, and autonomic regulation are shaped. The body may appear calm, but the system is still on. Still bracing. Still poised for a signal that never comes.

What we call "doing" in this model is not simply action. It is persistent mobilization in anticipation of threat. And what we call "being" is not the absence of action. It is a sensation of presence without defensive override. When these two states cannot regulate, the mind-body remain vigilant: on guard, unable to rest.


Conclusion: The Return to Being 

To “be” is not to withdraw from life’s demands, nor to float in some idealized stillness. It is to inhabit a form that is not contorted by anticipatory action. It is to remain within one’s own vertical axis - coherent in breath, posture, and interoceptive signal - even as the world moves.

In clinical terms, this means restoring the body’s capacity not to prepare. To let the Ren Mai speak without being silenced by sympathetic override. To allow the Yin Qiao to gather inward tone without collapse. To inhabit the spine from within, rather than bracing from behind. And to regulate emotion through somatic containment, not cortical control or suppression.

Most patients do not need to be taught how to be -- they need to be reintroduced to the conditions that make being possible. This is where our medicine excels. It reaches into the pre-verbal scaffolding of experience: the channels, the fascia, the autonomic set points, the shape memory of the self. When we treat not just what the patient is doing, but how they are held in the doing, we create a path back to being.

In The Undefended Self, therapist Susan Thesenga describes how early defenses distort the expression of our essential nature. She writes, “There is a real self that equals neither your negative aspects, nor your adamant self‑judgment, nor the pretense that covers up the negativity. To find this real self is our concern.”

This real self is not a constructed identity or a behavioral adaptation. It emerges when primitive defenses no longer organize perception and when anticipatory threat responses are no longer the body’s baseline.

When this shift occurs, something essential is recovered—not only ease, but orientation. The body no longer braces for what might come, and the mind no longer scrambles to manage what it cannot feel. Presence becomes possible, not as a concept, but as a physiological reality.

This state is not the result of striving, performance, or self-improvement. These forms of doing often mirror the very defenses they attempt to overcome. Rather, the capacity for presence returns when the body no longer organizes around anticipation, and the nervous system no longer equates preparedness with safety. What remains is not collapse, but the quiet coherence of being. From this ground, the real self—undefended and intact—can begin to emerge.
