If You Want to Know What is Inside Something, You Squeeze it

Tempering the Self – Cultivation through Pressure, Refinement and Purpose

In the tradition of martial arts and Taoist self-cultivation, the process of becoming a person of refined character, resilience and integrity is often portrayed metaphorically as a transformation under pressure or through rigorous refinement. Just as coal under intense pressure becomes a diamond, as glass is tempered to strengthen it, or as a sword is heated, hammered and folded until it offers purity, sharpness and endurance, so too does the aspirant put themselves through trials, reflection, disciplined training, and “taking apart” of habitual patterns in order to emerge stronger, clearer, and more whole. This essay explores that metaphorical terrain, linking historic Taoist concepts of cultivation with martial-art training and moral growth.

At the heart of the metaphor is the notion of pressure and refinement. A lump of coal, subjected to geological force over time, becomes a diamond: the original material has been compressed, purified, and transformed into something far harder and more brilliant. In a similar way, a glass object is heated and rapidly cooled (tempered) so that its structure changes, the internal stresses are intentionally introduced, then stabilized and thus the glass becomes more resistant to shattering. A sword likewise must be heated, hammered, folded, quenched, and polished; the metal structure is reorganized so that it can hold an edge, bend without breaking, and serve a purpose. Transposed to human character and training, these metaphors suggest that to become something more than we currently are, we must face pressure (external challenges, internal struggle), go through the restructuring of habit, belief, body and mind, and emerge in a usable state: strong, resilient, sharp of focus, yet tempered by insight.

In essence, this process represents a kind of transmutation, orthe transformation of one’s coarse, unrefined nature into a state of inner clarity and integrity. Just as physical elements change state under heat or pressure, the human psyche and spirit can evolve through disciplined practice and self-reflection. In Taoist internal alchemy, such transmutation marks the transition from density to subtlety, from the crude to the luminous.

In the realm of martial arts, and particularly those influenced by Taoist philosophy, this is not merely a nice poetic image, but an embedded structure of training. The discipline, repetition, discomfort, unlearning of ingrained patterns, and gradual internalization of principles all function like the hammer and heat of the swordsmith. As one trains, one is literally breaking down old neural/structural patterns of body and mind, refining them, and integrating them into something more coherent, more “whole” and more aligned with one’s higher potential.

From the viewpoint of Taoist self-cultivation, this process aligns with the paradigm of internal alchemy (neidan). Internal alchemy is described as a “transformation process that involves changing both body and mind to higher levels of functioning” (Fung Loy Kok Institute of Taoism, 2025). According to Taoist doctrine, one works with the “Three Treasures” (jing → qi → shen: essence, energy, spirit) and seeks gradual refinement of self (Wikipedia contributors, 2025). The aim is to dissolve coarse patterns (the raw coal), to apply “heat” and “pressure” in the sense of rigorous practice, moral confrontation, endurance, discipline, and then to emerge as something sharper, lighter, more refined, aligned with the Tao (道). This dynamic mirrors the alchemical notion of transmutation, in which base material (lead or raw essence) is refined into gold or spiritual purity. Taoist cultivation translates this symbolism into physiological and psychological terms: jing (essence) transmuted into qi (vital energy), and qi into shen (spirit), forming a continuum of self-refinement that bridges body, mind, and consciousness (Needham, 1983; Pregadio, 2019).

I prefer the metaphor of “if you want to know what is inside something, you squeeze it; if you want to know what something is made of, you take it apart and hopefully put it back together, maybe even better than the original.” In the training context, “squeeze” refers to tests and trials: one’s character is squeezed by adversity, by training drills, by mental stress. That brings to awareness hidden weaknesses of unseen fractures, untempered spots. “Taking apart” refers to the deconstruction of habit, belief, movement, reaction: in the martial arts one often unlearns bad posture, reflexes, tension, and rebuilds structure. Then one reassembles with new alignment, better structure, refined intent. The final state is not merely restored but upgraded, like a sword folded multiple times becomes stronger than the original billet; glass tempered is stronger than annealed glass; coal stressed in pressure becomes diamond.

In ethical or moral self-cultivation this means that facing one’s character under pressure reveals hidden fissures: impulsiveness, reactivity, unresolved fear, habit. Good training (physical, mental, moral) allows one to “see” those fissures, to let them be “heated” (examined, confronted) and “hammered” (repeated disciplined practice, correction) until the structure of self becomes more resilient, more integrated, more responsive rather than reactive. The Taoist culture encourages a kind of return to one’s original nature of goodness (德, de) and compassion, which has been obscured by life’s conditioning (Fung Loy Kok Institute of Taoism, 2025). The “sword” or “diamond” of self-character thus is not about hardness for its own sake, but a resilient clarity, readiness, humility, and refined responsiveness.

Moreover, the metaphor highlights the paradox: we often think that pressure or challenge is purely negative; yet in transformation systems, from geology to metallurgy to glass tempering, pressure and heat are required for refinement. In martial practice, avoidance of stress means never getting the internal re-working that occurs under challenge. In Taoist cultivation, the path is not easy but transformation. Indeed, the Taoist ideal of wú wéi or “effortless action” is often misunderstood; it is not doing nothing, but acting naturally from a well-tempered, integrated being (Wikipedia contributors, 2025). After the hammering, the sword is sharp without forced strength; the tempered glass resists shatter without brittle rigidity; the diamond shines because prior pressure created its internal perfection.

In integrating this into holistic and/or martial arts philosophy (Tai Chi, Bagua, Qigong, etc.), the training forms, the repetitive drills, the internal alignments, the meditations, the stance work, all of these provide the “pressure chamber” in which subtle weaknesses (postural misalignment, mental chatter, emotional reactivity) are exposed. We can “take apart” our default responses by slow mindful repetition, by breaking and rebuilding the body-mind link. Over time we can reassemble into someone who moves from center, aligned in structure, calm in mind, responsive in body, as the sword forged, the diamond formed. That formation is not only for combat or technique but for human character: greater clarity, sharper discernment, stronger resilience, deeper compassion.

Finally, the metaphors of glass and sword and diamond remind us that refinement is not about making something brittle or inflexible. A diamond is hard but also rare and valued; tempered glass remains flexible in the sense of resisting sudden break; a well-forged sword has strength but also resilience, edge but also integrity. The cultivated person is not rigid or inflexible, but resilient and discerning; not hardened by bitterness but refined by purpose. True cultivation (in Taoist terms) is returning to one’s original nature of goodness, clarity and unity with the Tao (Fung Loy Kok Institute of Taoism, 2025). Thus the journey of applying pressure, refining, deconstructing and reconstructing becomes a path to higher humanness.

Expanded Insight – Summary Table

MetaphorProcess in Training / CultivationOutcome in Character/Martial Path
Coal → DiamondUnder pressure, inner structure transformsResilience, clarity, inner strength
Glass temperedHeated and rapidly cooled, internal stresses made stableFlexibility + strength, capacity to absorb without shattering
Sword forgedHeated, hammered, folded, quenched and polishedPrecision, readiness, alignment, refined power
Squeeze/Take apart & rebuildTrials reveal hidden flaws; deconstruct habit; rebuild structureSelf-knowledge, refined movement/mind, upgraded character

  • The “squeeze” corresponds to facing real challenge, such as training under fatigue, mental adversity, resisting egoic impulses.
  • “Taking apart” corresponds to unlearning: posture, reflexes, mental habits, emotional reactivity.
  • “Putting back together” corresponds to rebuilding through alignment, mindful movement, meditative awareness, ethical discipline.
  • The end state is not perfection in the sense of rigidity, but refined flexibility, integrated power, clear purpose.


In summary, the metaphors of coal under pressure producing diamond, glass tempered, sword forged, and the squeeze/deconstruction/reconstruction process, are profoundly apt for describing a martial-art and Taoist vision of self-cultivation. They reflect an understanding that becoming a person of refined humanness involves more than mere physical technique: it demands pressure (challenge), refinement (attention, repetition, unlearning), rebuilding (integration of mind/body/spirit), and emergence into a state of character and ability that is both strong and flexible, sharp and compassionate.

In this sense, all of these metaphors of coal, glass, sword, and the squeeze, describe not only refinement but transmutation: the intentional evolution of the inner substance of the self through sustained practice, ethical tempering, and conscious transformation. In the Taoist tradition of internal alchemy, we see this very schema: transforming the body-mind through disciplined practice until one returns to original nature or emerges into a new, refined state (Fung Loy Kok Institute of Taoism, 2025; Komjathy & The Yuen Yuen Institute, 2008). These metaphors explicitly embody the concept of the Warrior, Scholar & Sage, as principles that connect physical technique with inner alchemical transformation, so that practitioners understand that the pressure in training is not incidental, but rather it is intrinsic to the forging and cultivation of their character.

Dim Mak, “Delayed Death Touch,” and the Myth of Physical Injury Without Contact

Origins and Lore

The concept of Dim Mak often translated “pressing the pulse/vessel”) occupies a curious place in martial lore. Sometimes referred to as the “delayed death touch,” it is imagined as a set of techniques targeting subtle points on the body to cause paralysis, unconsciousness, or even death, sometimes instantly, sometimes hours or days later. In Cantonese opera, wuxia fiction, and 20th-century martial arts marketing, this idea became a central trope. Related Japanese traditions, such as kyūsho-jutsu, also emphasize striking “vital points” (Kim & Bookey, 2008).

One historical root is the Bubishi, a Southern Chinese martial and medical manual carried to Okinawa and preserved in karate circles. It contains anatomical diagrams and pressure-point charts, blending medicine and combat knowledge. However, nothing in the Bubishi describes a reproducible “death touch on a timer.” The delayed-death legend is largely a product of mythologizing (McCarthy, 1995).

Physiological Realities

Although the notion of a mystical “death touch” has no scientific foundation, certain strikes can produce catastrophic effects. For example:

  • Commotio cordis: A sudden blow to the chest directly over the heart during a critical phase of the cardiac cycle can trigger lethal arrhythmias, especially in young athletes. Death is rapid, not delayed (Maron et al., 2010).
  • Carotid sinus reflex: Pressure or trauma at the neck can overstimulate baroreceptors, causing sudden fainting or, in rare cases, cardiac arrest (Sutton, 2014).
  • Internal injuries: Abdominal trauma may produce a delayed splenic rupture, with fatal bleeding occurring days after impact (Coccolini et al., 2017). Likewise, epidural hematomas following head trauma can present with a “lucid interval” before deterioration (Ganz, 2013). These medical realities may explain reports of “delayed death” after apparently minor strikes.

In short, so-called Dim Mak events correspond more closely to rare but recognized trauma complications, not an esoteric martial formula.

“Injury Without Touch” and Nei Gong

Claims that a Nei Gong (or neidan) master can injure or incapacitate another person without physical contact remain anecdotal and unverified. Controlled tests and skeptical investigations have repeatedly failed to reproduce reliable no-touch effects; where dramatic results are reported, more plausible explanations include expectancy and conditioned responses among students, theatrical staging or confederates, suggestion/hypnosis, and the nocebo/placebo effect. Importantly, some real medical conditions (for example, cardiac arrhythmia after blunt chest trauma or delayed intracranial bleeding) can cause delayed collapse and have sometimes been misattributed to mysterious causes — but these are documented trauma or medical events, not proof of transmissible ‘external qi.’ Because of the unpredictability of medical reactions, any attempt to provoke physiological responses in others without informed consent raises serious ethical and legal issues; responsible teachers therefore emphasize biomechanics, safety, and transparent demonstration methods rather than secret lethal techniques.

Some modern teachers link Dim Mak to nei gong (“internal work”) breath, alignment, and energetic exercises said to cultivate the ability to project qi or chi (vital force) externally. Demonstrations of “no-touch knockouts” or “chi projection” circulate widely, often framed as injury without contact.

Under controlled testing, however, such claims collapse. Televised investigations and academic studies show that subjects who are not suggestible or part of the teacher’s own group remain unaffected by “no-touch” attempts (Shermer, 1997). The most plausible explanation is psychological, where expectancy, compliance, or hypnotic influence are the cause, not physics or bioenergetics. Practitioners cannot safely test these methods without risking harm. Ethical training instead focuses on biomechanics, leverage, and simulation rather than attempts at real no-touch injury.

Why “injure without touch” raises serious moral problems

  • Unpredictable risk. Because some medical events (arrhythmia, stroke, internal bleeding) can be triggered unpredictably by stress or minor provocation, any attempt to produce physiological effects remotely risks serious harm. You cannot ethically justify causing that risk.
  • Consent & autonomy. Attempting to alter someone’s physiology or mental state without explicit, informed consent violates basic bodily and mental autonomy.
  • Deception and coercion. Teaching secret “no-touch” attack methods encourages deception, exploitation, and misuse, especially in hierarchical groups. That fosters abusive dynamics.
  • Legal exposure. Even “demonstrations” that cause collapse, panic, or later medical problems can produce criminal liability and civil suits. Teachers are responsible for foreseeable harm.

That said, nei gong is highly valuable when understood in biomechanical terms. Internal training improves body structure, breath regulation, and fa jin (explosive force issuance). This allows practitioners to deliver maximum impact with minimal motion and appear almost effortless. The “mystical” layer is metaphorical; the real effect is better mechanics (Frantzis, 2007).

Ethics and Modern Practice

Because of the risks of striking vulnerable areas, serious martial arts traditions emphasize responsibility. Knowing that a blow to the chest or neck could cause unforeseen medical emergencies, modern teachers stress restraint, safety protocols, and familiarity with first aid and CPR.

From a holistic view, Dim Mak reminds us that mythology often grows around kernels of truth. Striking the body does carry risk, but not in the cinematic, time-delayed fashion popularized in movies. Internal practices like nei gong do confer extraordinary skill, but by enhancing efficiency and coordination, not by transmitting lethal force through the air.

The Flow State Across Martial Arts, Qigong, and Meditation

Integrating Concepts of Mushin, Wu Wei, Song, and More

In Western psychology, being “in the zone” or in a “flow state” describes a mental state of deep absorption where time perception fades, awareness sharpens, and actions become effortless (Csikszentmihalyi, 1990). This state is not unique to modern science. In fact, many ancient practices such as martial arts, qigong, meditation, and the aesthetic traditions of the East, have long cultivated similar states using different terminology and methods.

While “flow” emphasizes optimal performance, many Eastern terms go deeper: they describe integration of body, mind, breath, and spirit, often in accord with the Dao or an underlying natural order. Let us explore these terms and their significance.

Martial Arts: Mushin and Zanshin

In Japanese martial arts, the state of flow is often described using the Zen-influenced term Mushin, meaning “no mind” or “empty mind.” It refers to a condition in which the practitioner acts without conscious deliberation, relying on trained reflexes and spontaneous awareness. The mind is free of distraction and fear; movements are clear and fluid (Herrigel, 1953).

Another related term is Zanshin, or “remaining mind.” This describes a calm, continuous state of alertness both during and after action, with a sustained, integrated awareness (Lowry, 1986).

Through rigorous training, repeated kata, sparring, and meditation, martial artists cultivate these states, allowing them to respond to changing situations naturally and without hesitation.

_______

Qigong and Tai Chi: Wu Wei, Song, Ziran, and Yi

In Chinese internal arts such as Tai Chi, Bagua Zhang, and other methods like Qigong, the flow state is cultivated through the integration of several core concepts:

  • Wu Wei: Effortless action. Rooted in Daoist philosophy, Wu Wei refers to acting in harmony with nature, without forcing or striving (Laozi, trans. Legge, 1891). Movements arise spontaneously, guided by deep awareness and connection to the environment.
  • Song: Relaxed yet structured looseness. Song is a key internal martial arts term meaning to release unnecessary tension while maintaining structural integrity. One does not collapse but rather cultivates a state of “alive relaxation” where Qi and movement can flow freely (Frantzis, 2006). True Song supports entering a flow state because body and mind are soft, open, and responsive.
  • Ziran: Naturalness or spontaneity. An expression of advanced internal arts practice, where movement flows without contrivance or self-conscious control.
  • Yi Nian and Yi: Single-pointed intent. In flow, the practitioner’s intention guides movement seamlessly, without overt mental effort.

Breath control, slow mindful repetition, and the cultivation of Song are critical methods for achieving this state in Qigong and Tai Chi. Over time, this leads to “moving meditation” as natural expression of flow.

Meditation and Zen: Dhyana, Samadhi, and Mo Nian

Meditative traditions in both Buddhism and Daoism have long described states equivalent to flow:

  • Dhyana / Chan / Zen: The state of deep meditative absorption where thought activity diminishes and awareness becomes unified and clear (Suzuki, 1956).
  • Samadhi: A condition of profound stillness and concentration where the practitioner merges with the object of focus, whether in seated meditation or in daily life. In Zen arts, this leads to flow in action.
  • Mo Nian: Silent awareness, a state where the practitioner moves or acts without inner verbalization, essential for flow in both meditation and movement disciplines.

Meditative flow emerges through long-term attention training and breath practices that stabilize awareness and diminish ego identification.

Aesthetic and Cultural Practices: Qi Yun Sheng Dong and Shin-Gi-Tai

The flow state is not limited to combat or health practices. In Chinese painting, calligraphy, and Japanese tea ceremony, similar ideals appear:

  • Qi Yun Sheng Dong: Spirit resonance giving life to the art. This describes the energetic liveliness and authenticity that arises when the artist enters a flow state through their medium (Cahill, 1994).
  • Shin-Gi-Tai: Unity of heart-mind, technique, and body. A Japanese term often used in martial and aesthetic disciplines, referring to the seamless integration of inner intent, technical skill, and embodied expression (Lowry, 1986).

Artists achieve this state through decades of technical refinement coupled with deep mental stillness, allowing spontaneous creativity to arise.

Summary Table: Key Terms for Flow in Eastern Practices

DomainTerm(s)Nature of Flow Experience
Martial ArtsMushin, ZanshinSpontaneous action and sustained awareness in combat
Qigong / Tai ChiWu Wei, Song, Ziran, Yi NianBreath-body-mind integration; relaxed yet dynamic responsiveness
MeditationDhyana, Samadhi, Mo NianUnified attention; timeless presence
Arts & AestheticsQi Yun Sheng Dong, Shin-Gi-TaiFlow through artistic expression and technical mastery

What modern science calls “flow” is deeply embedded in ancient mind-body disciplines. Concepts such as Mushin, Wu Wei, and especially Song describe not merely optimal performance, but the harmonization of self with nature and the present moment. Practitioners of martial arts, Qigong, and meditation seek not only to achieve flow for its benefits, but as a means of deep personal cultivation.

When body, breath, mind, and intention become one, Song releases tension, Yi guides movement, and Wu Wei allows action to arise naturally, the practitioner touches the essence of flow and embodies timeless wisdom.

Sae Hwalgi – “Renewed Energy”

The Path of Renewed Vitality and the Reality of Aging

In Korean martial arts and traditional language, expressions often carry layered meanings. One such expression is “Sae Hwalgi,” which literally translates to “new vitality” or “renewed energy.” At first glance, the phrase appears simple, but within martial instruction and holistic health contexts, it reflects both the natural vitality of youth and the inevitable decline of the body with age.

Linguistic Foundations

The phrase can be broken down into two key parts: Sae, meaning new or fresh, and hwalgi, meaning energy, vigor, or vitality (WordHippo, n.d.; Collins Dictionary, n.d.). In Korean everyday usage, hwalgi refers to liveliness and robustness, the spark of vigor that animates one’s daily life. In martial culture, however, the term also resonates with deeper energetic qualities, similar to the concept of qi (ki, or gi) – the life force that sustains movement and resilience.

Martial Perspective

For martial artists, aging creates a paradox. With experience comes wisdom, but with age comes loss of flexibility and suppleness. In youth, sae hwalgi manifests as hydrated tissues, supple joints, and rapid recovery. With age, however, connective tissues lose hydration, collagen stiffens, and movements that were once effortless become labored.

Research in connective tissue physiology supports this traditional observation. Studies have shown that aging reduces elastic fibers and hyaluronan content in muscles, while collagen type I increases, creating stiffness and functional decline (Fede et al., 2022). Martial masters may describe this process metaphorically as the loss of hwalgi, reminding practitioners that vitality is not permanent but must be cultivated.

The Science of Aging Tissues

From a biomedical perspective, hwalgi correlates with measurable changes in the body. Collagen loss, a systemic process associated with cellular aging, directly impacts tissue elasticity and hydration (Collagen loss, 2025). Fascia, the web of connective tissue supporting movement, is also profoundly affected by aging. Maintaining fascia through elastic training, hydration, and mobility work is crucial for sustaining vitality (Petersen, 2015).

These physical realities mirror what martial language describes: the transition from supple vitality (sae hwalgi) to diminished energy and rigidity as time passes.

Holistic Dimension

The decline of vitality is not purely physical. In holistic traditions, vitality depends on the balance of body, mind, and spirit. A calm, focused mind preserves energy, while a scattered or stressed mind depletes it. Similarly, qi depends on unobstructed circulation through meridians. Stress, stagnation, and aging create blockages that restrict this flow, contributing to both physical stiffness and mental fatigue.

Thus, sae hwalgi is not just a description of youthful elasticity but a call to action: to cultivate renewal of vitality through breath, awareness, and lifestyle practices that harmonize mind and body.

Renewal Practices: Cultivating Sae Hwalgi

While aging cannot be reversed, vitality can always be renewed in relative terms. Modern science and traditional practices converge on this principle. Ways to cultivate sae hwalgi include:

  1. Breathwork – Deep diaphragmatic breathing regulates the autonomic nervous system and restores energy balance (Petersen, 2015).
  2. Hydration and Nutrition – Adequate water and mineral intake support tissue elasticity (Fede et al., 2022).
  3. Movement and Fascia Training – Martial forms, qigong, and mobility drills help fascia remain hydrated and resilient (Petersen, 2015).
  4. Mental Clarity and Stress Management – Meditation prevents energy “leakage” and supports qi flow.
  5. Adapting Martial Practice – Shifting from sheer force to refined technique preserves energy and allows martial arts to be practiced into old age (U.S. Kido Federation, 2024).

Conclusion

The wisdom of sae hwalgi lies in its dual nature. On one hand, it embodies the vigor of youth and the freshness of life’s energy. On the other, it acknowledges the inevitable loss of that vitality with age. Yet it is ultimately a hopeful concept. Through martial practice, breath, movement, and holistic awareness, vitality can be renewed at any stage of life.

For the martial artist, sae hwalgi is not a static state but a living reminder: though time may stiffen the body, the choice to renew vitality always remains.
