Understanding the Korean Lunisolar Calendar and Mystical Time Cycles

In Chinese and Korean astrology and traditional cosmology, time is conceptualized as cyclical and governed by natural forces. These systems are used in saju analysis, geomancy, and ritual calendars. Two fundamental components of this worldview are:

The 10 Heavenly Stems (Tian Gan – Chinese), Cheon‑gan – Korean)
The 12 Earthly Branches (Di Zhi– Chinese), (Ji‑ji – Korean)

Together with the Five Elements (Wuxing) and Yin – Yang duality, they create a sexagenary (60-day) cycle that is the basis for identifying auspicious days and mapping personal fate (Lee, 1981).

Part 1: The 10 Heavenly Stems (Cheon‑gan)

The Heavenly Stems are a 10-day cycle derived from the Five Elements:

Wood (木) – Spring
Fire (火) – Summer
Earth (土) – Transition
Metal (金) – Autumn
Water (水) – Winter

Each element has a Yang (active) and Yin (receptive) form, yielding 10 total stems (Yoon, 2017).

These stems are associated with cardinal directions and form the energetic “climate” of each day:

Korean version of the 10 Heavenly Stems (Cheon‑gan)

Number	Stem	Element	Polarity	Direction
1	갑 (Gap)	Wood	Yang	East
2	을 (Eul)	Wood	Yin	East
3	병 (Byeong)	Fire	Yang	South
4	정 (Jeong)	Fire	Yin	South
5	무 (Mu)	Earth	Yang	Center
6	기 (Gi)	Earth	Yin	Center
7	경 (Gyeong)	Metal	Yang	West
8	신 (Sin)	Metal	Yin	West
9	임 (Im)	Water	Yang	North
10	계 (Gye)	Water	Yin	North

These rotating influences affect feng shui, health, and calendar-based rituals (Wu, 2005)

Part 2: The 12 Earthly Branches (Ji‑ji)

The Earthly Branches create a 12-day cycle and are symbolized by the 12 zodiac animals. Each branch has corresponding elemental, directional, and seasonal meanings.

Korean version of the 12 Earthly Branches (Di Zhi)

Branch	Animal	Element	Direction
자 (Ja)	Rat	Water	North
축 (Chuk)	Ox	Earth	NNE
인 (In)	Tiger	Wood	NE
묘 (Myo)	Rabbit	Wood	East
진 (Jin)	Dragon	Earth	ESE
사 (Sa)	Snake	Fire	SE
오 (O)	Horse	Fire	South
미 (Mi)	Goat	Earth	SSW
신 (Sin)	Monkey	Metal	SW
유 (Yu)	Rooster	Metal	West
술 (Sul)	Dog	Earth	WNW
해 (Hae)	Pig	Water	NW

Each day of the lunar month has an assigned branch, and this is one way that daily energy is determined (Kim, 2018).

Part 3: The 60-Day Cycle (Yukship Gapja)

Because 10 and 12 have a least common multiple of 60, this pairing forms a cosmological sequence that completes once every 60 days or years, depending on the calendar scale (Lee, 1981).

This cycle underlies:

Daily calendar rotation
60-year birthday celebrations
Spiritual timing for rituals and divination

The 60 units are viewed as elementally distinct days, each with specific fortune or taboo status.

Part 4: Special Days in Korean Mystical Practice

1. Sonnal – Unlucky Days

Rather than being “auspicious,” these are dangerous or unlucky days, often tied to folk shamanic beliefs. They are days when:

One should not cut hair or nails
Surgery or travel is discouraged
Avoid beginning manual tasks with construction, cutting, repairs, etc.
Spirit intrusion is considered high (Kim, 2018)

2. Gil-il – Lucky Days

These are selected based on:

Stem–branch harmony (Heavenly Stem supports the Earthly Branch)
Lack of elemental conflict with the person’s saju chart
Favorable directional flow based on geomantic readings (Yoon, 2017)

In rural traditions, agricultural festivals or ancestral rites are often aligned with these dates. These are perceived as the best days for weddings, moving into a house, starting businesses, making kimchi, conceiving a child.

3. December as Auspicious?

There is some belief that the lunar month aligned with Rat (Ja-wol), roughly December in the Gregorian calendar is energetically potent, because:

It is the start of the solar calendar (dongji, or winter solstice, marks the return of yang energy)
It represents fertility and rebirth in seasonal logic (Wu, 2005)

However, no universal doctrine marks December as always auspicious; it depends on the year’s alignment and individual energy patterns.

Part 5: Application in Korean Spiritual Life

Saju-palja: Four Pillars of Destiny combines year, month, day, and hour to forecast character, fate, and life timing. Each pillar has a stem–branch combination.
Pungsu-jiri: Korean geomancy uses directional alignments of time and space based on these cycles, to site homes, graves, and sacred spaces (Yoon, 2017).
Almanac Use: Traditional Korean almanacs list each day’s stem–branch, auspicious tasks, and prohibitions.

Conclusion

The purpose of this article is not to judge or critique these particular belief systems, but rather offer information on differing perspectives. The integration of Heavenly Stems, Earthly Branches, Five Elements, and Yin-Yang philosophy produces a deeply symbolic and cyclical framework for interpreting time in Korean mysticism. Whether identifying auspicious dates, planning ancestral rites, or decoding one’s destiny, these systems offer a structured metaphysical map of existence. Understanding them opens a window into a worldview where time, space, and spirit are intimately connected.

The Student Becomes the Master, and the Master Becomes the Student

Across human history, the progression from student to master has symbolized growth, transformation, and the unfolding of wisdom. This dynamic relationship is not a simple ascent from ignorance to knowledge but a cyclical process of continual renewal. The journey encompasses humility, discipline, and self-realization, leading to a profound paradox: when the student attains mastery, the master must again become a student. This recursive pattern reflects the principles of Eastern philosophy, particularly Taoist and Confucian thought and aligns with modern educational theories emphasizing lifelong learning and self-reflection.

The Student’s Path Toward Mastery

The journey begins with a recognition of one’s limitations and a willingness to learn. Confucius emphasized humility and perseverance as the foundations of wisdom, observing that “to learn without thinking is labor lost; to think without learning is perilous” (Analects 2:15; Confucius, trans. 1997). In this early stage, the student relies on imitation and structured practice. The discipline of repetition is common to both martial and academic traditions, laying the groundwork for understanding.

According to Dreyfus and Dreyfus’s (1980) model of skill acquisition, learners progress through stages from novice to expert, eventually developing intuition born of experience. In martial arts or philosophy, this phase marks the transition from external technique (jing) to internal essence (shen). As the student refines skill through practice and reflection, understanding becomes embodied knowledge, not merely intellectual comprehension.

Taoist philosophy describes this evolution as harmony between wu wei (effortless action) and ziran (naturalness), where mastery manifests as unselfconscious expression (Laozi, trans. 1963). The master no longer performs from memory but from presence. This state of integration unites form and spirit, leading to authentic mastery.

The Master’s Return to Studenthood

True mastery dissolves the illusion of finality. As Zen teachings remind us, “In the beginner’s mind there are many possibilities, but in the expert’s there are few” (Suzuki, 1970, p. 21). The master who clings to certainty ceases to evolve. Thus, mastery demands a return to humility, with a willingness to once again become the student.

In this reversal, the teacher learns from experience, from new disciplines, and from students themselves. This concept parallels Schön’s (1992) model of reflective practice, wherein professionals continually re-examine their assumptions and adapt to changing circumstances. The act of teaching becomes itself a form of learning; the master refines understanding through articulating, demonstrating, and witnessing the struggles of learners.

Taoism and Zen Buddhism alike emphasize the cyclical nature of wisdom: knowledge transforms into unknowing, fullness returns to emptiness, and mastery flows back into inquiry (Watts, 1957). The wise master recognizes that wisdom is inexhaustible, and therefore, every conclusion opens new questions.

The Yin–Yang of Learning and Teaching

The relationship between student and master reflects the balance of yin and yang. The student, receptive and absorptive, represents yin, the principle of stillness and potential. The master, expressive and guiding, represents yang, the principle of activity and realization. Yet within each is the seed of the other. When yin and yang harmonize, growth continues.

In Confucian tradition, learning (xue) and reflection (si) are inseparable (Confucius, trans. 1997). Similarly, in martial philosophy, the practitioner cycles between discipline and spontaneity, form and formlessness. The process ensures that wisdom remains fluid rather than rigid, evolving with each generation. As the master learns anew from teaching, the lineage of knowledge remains living and dynamic in a continuous circle rather than a vertical hierarchy.

Conclusion

The transformation from student to master and back to student encapsulates the eternal rhythm of growth. Both roles coexist within the same individual, manifesting as phases in an endless cycle of becoming. Mastery is not the termination of learning but its most refined form. A state of perpetual openness and renewal.

As modern educators and ancient sages alike affirm, the essence of wisdom lies in humility. The student becomes the master by integrating knowledge into being. The master becomes the student by recognizing that learning never ends. Thus, the truest path of mastery is circular, infinite, and alive reflecting the natural flow of the Tao itself.

Drinking from the Well, Denying the Source

The Conscious Exploiter: When Awareness Replaces Gratitude

In human relationships, it is natural to give and to hope that our giving is met with acknowledgment, respect, or at the very least basic appreciation. But what happens when someone receives generously, with full awareness of the giver’s effort or sacrifice, yet responds with silence, indifference, or calculated detachment?

This is the subtle, unsettling behavior of what we may call a conscious exploiter. A person who takes with mindfulness but withholds gratitude by choice.

Unlike the oblivious or socially inept, the conscious exploiter is often intellectually aware and emotionally capable but operates with an internal moral economy that excludes reciprocation. Their mindset resembles a form of calculated opportunism, wherein taking becomes justified through rationalizations, entitlements, or social positioning. As psychologist George Simon explains in In Sheep’s Clothing (2010), manipulative personalities often know what they’re doing but frame their actions to appear innocent or justified, making their ingratitude seem subtle or even acceptable (Simon, 2010).

Gratitude as a Marker of Moral Awareness

Gratitude is more than a polite gesture; it’s a sign of mutual recognition, emotional intelligence, and social maturity. Psychologist Robert Emmons, a leading researcher in gratitude science, describes it as “a relationship-strengthening emotion” that connects giver and receiver in a mutual bond of awareness (Emmons & McCullough, 2003). When someone consciously receives but fails to show appreciation, they break the cycle of relational reciprocity, often creating emotional imbalance and mistrust.

Yet in modern society, especially in competitive environments or hierarchical communities, this behavior can become normalized. When success or advantage is prioritized above virtue, even intelligent and aware individuals may suppress expressions of gratitude to maintain power, status, or detachment.

The Ethical Cost of Calculated Ingratitude

From a philosophical lens, this conduct undermines ethical living. The Stoics, such as Seneca, warned of taking without gratitude as a sign of moral decline, arguing that “he who receives a benefit with gratitude repays the first installment on his debt” (On Benefits, trans. Basore, 1935). In Taoist tradition, the natural flow of energy (or qi) depends on balance and reciprocity, not unilateral absorption. To receive while withholding thanks is to disrupt the harmonious flow that underpins healthy relationships.

Such individuals may outwardly maintain charm, social grace, or even spiritual language, but their inner posture remains self-serving. They are “courteous faces masking consuming hearts,” quietly draining emotional resources from those around them.

Recognizing the Pattern

The conscious exploiter is not always easy to identify. Their ingratitude is not loud; it is quiet, measured, and often cloaked in charisma or deflection. You may notice:

They accept help readily but never inquire about your well-being.
They benefit from your time, knowledge, or effort, yet leave without acknowledgment.
They strategically maintain relationships that serve their needs, but dissolve or ignore those that ask for emotional investment.

Unlike the unaware, these individuals choose not to give back. Not out of inability, but out of intention.

Healing the Pattern

For those affected by such dynamics, healing begins with clear boundaries, conscious awareness, and a return to self-honoring. Recognize the signs not with bitterness, but with clarity. You are not obliged to pour into vessels that give nothing in return. As spiritual teacher Gabor Maté emphasizes, boundaries are not walls, but necessary structures to protect your energy and values (Maté, 2022).

Unseen Wounds: How Emotional Trauma Shapes Our Health

Despite living in an age of advanced medicine and rising health awareness, chronic illness, emotional suffering, and addiction continue to rise. This contradiction invites us to question not just our treatments but also the mindset and motivations behind them. Increasingly, research and lived experience point to unprocessed pain and trauma as the core drivers of both psychological and physiological illness.

Medicine’s Narrow Focus: Suppressing Symptoms Instead of Healing

Contemporary medical practices often focus on symptom suppression rather than root-cause healing. For example, elevated cortisol, a hormone associated with stress, is frequently managed with pharmaceuticals that reduce inflammation but fail to address the underlying source of distress (Sapolsky, 2004). In cases of chronic illness, especially cancer, mainstream interventions often fall back on drastic methods: cutting (surgery), poisoning (chemotherapy), or burning (radiation), with minimal inquiry into psychosomatic or emotional contributors.

The pharmaceutical industry has also come under scrutiny for prioritizing profit-driven solutions that treat stress biochemically without offering tools for actual emotional or relational healing (Gabor Maté, 2010).

A Society Obsessed with Health Yet Unwell

We live in a paradoxical society: obsessed with fitness, diet, and health optimization, yet disconnected from authentic well-being. Emotional pain is frequently seen as a personal failure, and expressions of vulnerability are often equated with weakness. Shame becomes a hidden driver of behavior, shaping identity through internalized messages like “I’m not enough” or “My needs don’t matter” (Brown, 2012).

The metaphor of the “monster” within, like the transformation of Bruce Banner into the Hulk, illustrates how repressed emotions can erupt when unacknowledged. We often assume that other people’s issues are about us, leading to further internal conflict and disconnection.

Trauma: The Root Cause of Addiction and Illness

Pain, especially unresolved emotional pain, is at the root of many afflictions. According to trauma expert Gabor Maté (2008), addiction is not a disease or choice but a response to deep suffering. Whether through substances, work, food, or achievement, people are often trying to soothe pain they may not even fully understand.

Social disconnection, abandonment, and lack of emotional education perpetuate trauma across generations. Society offers little support or guidance for managing grief, shame, or stress. Many turn to coping mechanisms without the tools to process their trauma, which is especially evident in marginalized communities where chronic stress is linked to disproportionately higher rates of illness (Williams & Mohammed, 2009).

The Cost of Disconnection and the Need for Authenticity

In professional fields like medicine, unresolved trauma is common. Some individuals pursue high-achieving careers not from passion but to compensate for feelings of inadequacy or unlovability. Emotional detachment, often a survival strategy in childhood, becomes normalized in adulthood. This disconnection between mind and body leads to chronic stress, illness, and burnout (Van der Kolk, 2014).

Authentic healing requires honoring two essential human needs: attachment and authenticity. When these needs are in conflict, as they often are in trauma survivors, authenticity is usually sacrificed for the sake of relational survival. Reconnecting with one’s truth, expressing anger constructively, and embracing emotional honesty are key steps toward transformation.

Healing the Generational Wounds

Trauma doesn’t disappear. It is often passed from one generation to the next, not just through genetics but through behavior, belief systems, and emotional suppression. Children absorb the stress of their caregivers. Without awareness and intervention, these patterns replicate over time (Yehuda & Lehrner, 2018).

What may appear as weakness, in hypervigilance, dissociation, emotional volatility, is often a response to longstanding unmet needs. Healing begins by naming these patterns and allowing space for expression and integration.

A Shift Toward Integration and Compassion

The healing path is not just clinical, it is relational, emotional, and spiritual. Psychedelic-assisted therapy, somatic practices, plant medicines like ayahuasca, and trauma-informed psychotherapy are gaining traction because they center empathy, connection, and emotional truth (Carhart-Harris & Goodwin, 2017).

As we reevaluate addiction, trauma, and illness through this lens, we begin to see that these challenges are not signs of brokenness. Rather, they are indicators of what needs acknowledgment, healing, and reintegration. Addiction, far from being a moral failure or inherited defect, can be seen as a solution to an emotional problem, a cry for help that must be understood before it can be addressed.

Nei Dan (Inner Alchemy)

Nei Dan (nae gong, neigong) often translated as “Inner Alchemy,” is one of the most profound and esoteric branches of Daoist cultivation and traditional martial arts training. Unlike Wai Dan (or Wei Dan), or “external alchemy,” which historically referred to concocting elixirs from minerals and herbs, Nei Dan is an internal process of refining and transforming the body’s vital energies (jing, qi, and shen) into higher states of vitality, consciousness, and spiritual realization. This internal alchemical process forms the energetic and philosophical foundation of many advanced martial, meditative, and spiritual practices across Daoist, Chan Buddhist, and certain Confucian lineages.

Historical Origins and Evolution

Daoist Roots (circa 3rd–8th century CE):
Nei Dan emerged from early Daoist cosmology and longevity practices (yangsheng), evolving alongside classical texts such as the Dao De Jing, Zhuangzi, and later the Cantong Qi, (The Seal of the Unity of the Three), often considered the foundational text of internal alchemy (Pregadio, 2019). Early Daoist alchemists saw the human body as a microcosm of the cosmos, mirroring the same dynamic interplay of yin and yang, five elements (wuxing), and celestial cycles. The goal was to harmonize and refine these internal forces to return the practitioner to their original, undifferentiated state (yuan jing, yuan qi, yuan shen).

Tang–Song Dynasty Expansion (7th–13th century):
During the Tang and Song dynasties, Nei Dan was codified into systematic schools such as the Zhong-Lü and Nanzong lineages. These schools emphasized an internal “elixir” (neidan dan) formed through disciplined meditation, breath regulation, and energetic circulation, paralleling the external alchemical metaphor of refining base metals into gold. At this time, martial traditions, especially those influenced by Daoism and Chan Buddhism (e.g., Shaolin and Wudang), began incorporating these principles into their training as a means of enhancing internal power (nei jin), awareness, and longevity.

Integration into Martial Arts (Ming–Qing era onward):
By the late imperial era, Nei Dan principles had become inseparable from Nei Jia Quan (“internal martial arts”) and most notably Taijiquan, Xingyiquan, and Baguazhang. These arts used the body as a vessel for alchemical transformation, with martial techniques functioning as vehicles for energetic refinement and spiritual cultivation. Masters such as Zhang Sanfeng (legendary founder of Taijiquan) and Dong Haichuan (founder of Baguazhang) are often described in Daoist alchemical terms, emphasizing internal stillness, energy transformation, and the unity of movement and spirit.

Core Principles and Goals of Nei Dan

At its essence, Nei Dan is a lifelong path of internal transformation. The traditional Daoist saying — “Refine jing into qi, refine qi into shen, refine shen and return to emptiness” outlines the three fundamental stages:

Refining Jing:
- Jing refers to “essence” – the foundational life force associated with physical vitality, sexual energy, and genetic potential.
- Practices in this stage focus on conserving and strengthening jing through lifestyle discipline, breath regulation, and daoyin exercises. This builds the “alchemical furnace” in the lower dantian, or the body’s energetic cauldron.
Transforming Qi:
- Once jing is stabilized, it is “cooked” into qi, which is the vital energy that flows through the body’s meridians.
- Breathwork (tu-na), microcosmic orbit circulation (xiao zhoutian), and standing post practices (zhan zhuang) are common methods. Martial expressions of this phase include issuing power (fa jin) and unifying breath with intent (yi qi heyi).
Refining Shen:
- Shen, or “spirit,” is consciousness itself. At this level, practice aims at expanding awareness, cultivating emptiness (xu), and returning to the primordial source (dao).
- Deep meditation, visualization, and contemplative stillness are central practices, often accompanied by subtle internal energetic processes described metaphorically as “the embryo of immortality” (shen ying).

Practices and Methods Involved

– Breath and Energy Regulation (Tiao Qi):
Controlled breathing (tu-na) is fundamental, teaching practitioners to guide qi consciously through the meridians. The microcosmic orbit (circulating qi along the du and ren vessels) is one of the most well-known techniques.

– Posture and Structure (Tiao Shen):
Postural alignment, rooted stance work (zhan zhuang), and slow, continuous movement (e.g., Taiji or daoyin) build the vessel for qi cultivation. Internal martial arts often hide alchemical work within physical movement.

– Mental Focus and Intention (Tiao Xin):
Training the mind (yi) to direct energy (qi) is central. Practitioners cultivate stillness (jing), intention (yi), and awareness (shen ming), often through visualization of internal alchemical processes.

– Sexual Alchemy (Fangzhong Shu):
Though often misrepresented, sexual alchemy is a legitimate component in many Nei Dan systems. It involves the conservation and refinement of sexual energy (jing), transforming it into spiritual power rather than expending it.

– Meditative and Cosmological Practices:
Advanced practitioners engage in meditations synchronizing their internal rhythms with cosmic cycles (e.g., lunar, solar, and seasonal changes) reflecting the Daoist belief in harmonizing microcosm and macrocosm.

4. Nei Dan in Esoteric Martial Arts

In the context of esoteric martial arts, Nei Dan is not simply health practice, but rather it is a method of refining the warrior’s spirit. The martial applications go far beyond fighting techniques:

Enhanced Internal Power: Cultivation of nei jin allows practitioners to issue force with minimal muscular effort.
Heightened Awareness: Refining shen deepens perception, intuition, and responsiveness, essential traits in high-level combat.
Transformation of Self: Martial practice becomes a vehicle for self-mastery, transcending ego and aligning the individual with the Dao.

Some lineages, such as certain Wudang Daoist sects, Xingyi Nei Gong, or the “Eight Immortal Methods” of Baguazhang, embed Nei Dan principles so deeply that combat forms double as alchemical formulas, guiding practitioners through progressive energetic transformations.

5. Legacy and Contemporary Practice

Today, Nei Dan is studied worldwide, both as a martial discipline and a spiritual science. In modern qigong, taiji, and neigong schools, the terminology may vary — yet the underlying process remains unchanged: the transformation of the human being from a coarse, ordinary state to one of luminous awareness and harmonious unity with the Dao.

It is said in the Daoist classics:

“The elixir is not found in mountains or seas. It is found within one’s own body.”

This aphorism encapsulates the essence of Nei Dan: the human being is the laboratory, the mind is the alchemist, and the Dao is the final elixir.

Sānbǎo: Jing–Qi–Shen — essence, energy, spirit.
Three Dantians: lower (vital/structural), middle (affective/relational), upper (cognitive/awareness).
Micro/Great orbits – conduction along Conception/Governing vessels (small), then through full channel network (great).
Huǒhòu: “Fire timing” — dosage, intensity, and pacing of practice.
Nèi jìn: Internal (elastic) power arising from whole-body integration and refined fascia/pressure dynamics.
Safety: Over-forcing breath, heat, or sexual practices can destabilize mood, sleep, or blood pressure; increase gradually, emphasize recovery.
