Early practice taught me how to evoke a sensation at a single point. What followed was a more complex process: the integration of isolated nodes into lines and eventually segment-based structures—a shift that reshaped how I understood attention and polarity.
Learning to Activate a Single Point
Learning to apply the right intention and focused attention to a single point, making the sensation arise, was the essential first step. But I soon realized this was far from sufficient.
With practice, I could feel the sensation at one point and then “move” it to the next simply by shifting my attention. However, as soon as my focus left the first point, the sensation there would vanish. I could only ever feel one active node at a time.
It felt like learning to flex a single, isolated muscle while the rest of the body remained inert. If this were the limit of the practice, I began to wonder whether the entire endeavor was worthwhile. The sensation itself was profound, but this fragmented perception felt incomplete.
From Points to Polarity: The First Breakthrough
My first systematic exploration focused on the Microcosmic Orbit. Initially, I simply passed my attention from node to node along the Du Mai, watching the sensation bloom and then fade behind me like a light being switched on and off.
The breakthrough came with the idea of making one node exhale (radiate, yang) while the next inhaled (absorbed, yin). This not only revealed the second polarity of the sensation but also showed me that I could focus on two points simultaneously and make them interact.
Still, managing two points felt like a rudimentary skill. I suspected that the real challenge was to feel the entire length of the Du Mai at once, from tailbone to crown—to perceive the line, not just the dots.
Neural Inertia and the Spinning Plates Analogy
To explore this, I devised a simple technique: rapid, rhythmic shifting of attention. Starting at the tailbone, I would move to the sacrum. The sensation at the tailbone faded, but not completely. Moving next to the Ming Men, the sacrum dimmed, yet a faint echo remained.
Crucially, when I cycled my attention back to the tailbone, I found it was not starting from zero. A residual hum of activity persisted—a kind of neural afterglow that required only a moment of focused attention to reignite fully. The same was true for each point in the sequence.
At least phenomenologically, I had discovered that neural activation seemed to have inertia. It didn’t vanish the instant attention moved elsewhere; it decayed gradually, like a spinning top losing speed.
The process became analogous to a circus act involving spinning plates. One plate is set spinning, then the next, and the performer must keep returning to each before it falls. By cycling my attention rapidly among multiple points—returning to each before its “spin” fully decayed—I learned to sustain the sensation in three, then four, then many nodes at once.
Gradually, the individual points began to blend. The discrete flashes of sensation merged into a continuous, humming line of awareness. I was no longer jumping from point to point; I was holding the entire channel in a sustained, coherent state of activation.
Lateral Integration in the Macrocosmic Orbit
This process unfolded over extended practice and overlapped with my exploration of the Macrocosmic Orbit. Here, the configuration was different: multiple vertical lines instead of one. There was not a single line to explore in the front and back, as happened in the MCO, now the lines came in pairs, with bilateral symmetry, so I adopted a different strategy.
Rather than focusing on a single vertical channel, I worked laterally. I would activate a point on the left side until it gained intensity, then shift my attention to the corresponding point on the right until the sensation matched. By oscillating attention rhythmically between the two, I learned to sustain both simultaneously.
This revealed a synergy that my earlier practice had not. Activating opposing lateral nodes generated a powerful, distinct sensation in the midline of the body—a feeling I could never access by working with vertical channels in isolation.
The Emergence of a Central Axis
In the torso, this effect was particularly striking. The structure that emerged—two lateral lines with a stronger central sensation arising between them—vividly reminded me of the yogic triad of Ida, Pingala, and Sushumna.
My simple technique of shifting attention from left to right seemed to capture the functional essence behind the symbolic crisscrossing of Ida and Pingala in traditional diagrams, a feature that had puzzled me for a long time.
The next experiment followed naturally. I applied the same principle to the original vertical pair: the Du Mai (back) and the Ren Mai (front). Focusing simultaneously on opposing nodes along these channels produced the same kind of synergistic effect. The central sensation that emerged closely resembled what Daoist texts describe as the Chong Mai, or Thrusting Channel.
Nothing else activates.
Same result: nothing else activates.
In that moment, the two systems—Ida–Pingala–Sushumna and Du Mai–Ren Mai–Chong Mai—appeared less like separate maps and more like complementary descriptions of the same underlying mechanism: the generation of a central axis through the balanced activation of opposites.
From Lines to Segments
This realization opened a new line of inquiry. My torso map did not consist of four vertical lines, but eight. Having observed the effects of activating just two opposing points, the next question became unavoidable: what would happen if all eight points at a single horizontal level could be activated simultaneously?
If all components were present, there had to be a way for them to function as a unified whole. The linear structure of channels was compelling, but this emerging segment-based organization—achieved through the integration of isolated nodes—seemed far more powerful. That realization marked the transition to the next phase of exploration.
