When people come to their first Body & Brain class, they often don't know quite what to expect. Most assume it will feel like a yoga class or a gentle exercise session. And in some ways, it does — there is stretching, breathing, movement. The body works. Energy begins to move.
But then something else happens.
Some people feel unusual warmth spreading through the body. Others notice their hands tingling in a way they have never felt before. Some feel their body begin to move almost on its own — subtle, spontaneous shifts and vibrations that no one told them to do. And some feel waves of emotion arrive without warning: tears they can't explain, or laughter, or a deep, unexpected sense of well-being.
If you experience any of this, you are not imagining it. Your body is healing.
The Vibration of Life
Many changes occur in the body during Body & Brain Yoga practice, and they differ from person to person. When energy begins to flow — really flow, through meridians that may have been blocked or sluggish for years — the body responds. It shakes, sometimes subtly and sometimes visibly. It moves. It releases.
This is comparable to turning a garden hose on full blast after the water has been barely trickling. With the sudden increase in pressure, the hose begins to shake and move. The body does the same when energy suddenly begins to flow freely through the meridians.
There are two types of vibration we commonly see. The first occurs when sufficient energy accumulates in the dahnjon — the body's core energy center in the lower abdomen — and begins to move rapidly through the meridian channels. The second occurs when the mind opens deeply (often accompanied by emotional release) and receives an influx of the universal energy that is always available to us. Both are signs that practice is working.
Most people feel genuinely refreshed after experiencing this vibration. The mind feels steady and clear. The body feels lighter. In the days that follow, energy flows freely through unblocked channels, allowing for continued releasing and refreshing.
Myunghyun: When Darkness Precedes the Light
There is another phenomenon that sometimes occurs as the body begins to open — one that is less immediately comfortable but equally important to understand. We call it Myunghyun, a Korean word that holds two meanings simultaneously: brightness (myung) and darkness (hyun).
When the energy system begins releasing what it has been holding, the process is not always smooth. Old layers of stagnant energy, stored tension, and accumulated stress begin to shift and clear. As they do, some practitioners experience what might feel, temporarily, like things getting worse before they get better.
Think of it as an ‘energy detox’, the same way a physical cleanse can bring temporary discomfort as the body releases what it has been holding, the energy system does the same.
This can look like unexplained fatigue or flu-like symptoms that pass within a few days. It can be an old pain briefly returning to the surface, or unusual sensations — heat or cold emanating from the center of the body, persistent vibration in a limb, or bruise-like marks appearing at sites of old injuries. Some people experience emotional Myunghyun — sudden mood shifts, unexpected waves of sadness or anger, even grief that surfaces without an obvious cause.
These symptoms are not signs that something has gone wrong. They are signs that the body is actively restoring itself — that the healing intelligence within you has been activated and is doing exactly what it is designed to do. Body & Brain Yoga exercises help to accumulate and activate energy, allowing the system to become lighter and brighter. Stagnant energy is eliminated. What remains is cleaner, freer, and more vital.
When Myunghyun arises, the most important thing is to stay positive, keep practicing, and if you are attending a class, speak with your instructor. Where the mind goes, energy follows. A confident, accepting mind supports efficient, balanced self-healing.
What You Are Restoring
Beneath all of this — beneath the warmth, tingling, tears, and the spontaneous movement — something essential is being restored.
The body has its own healing intelligence. Given time and energy, it knows how to regulate, repair, and renew. This practice helps you face the obstacles blocking this process and reconnect with the power and light that has always been within.
