Roots of the I Ching

Yin Yang symbol roots of I Ching

To understand the I Ching or Book of Changes, we trace the universe back to its root elements, where the silent mystery of Tao gives rise to the vital breath of Ch'i, unfolding into the complementary forces of Yin and Yang.

Through this interplay, the myriad forms of existence emerge, each expressing its own nature as Te—the inherent character and vitality through which Tao expresses itself in the individual.

These concepts and their relationship can best be described as:

Tao - the source, the great mystery from which everything arises.

Ch'i - the vital breath or animating energy through which Tao manifests.

Yin and Yang - the complementary forces through which Ch'i moves, transforms, and creates.

Te - the inherent nature, vitality, or potency through which each thing expresses its unique relationship to Tao.

The ten thousand things - the countless forms of life and existence arising through this unfolding.

Tao, Ch’i and Te

The sages of ancient China did not view the universe as a collection of separate objects, but a fluid continuum of Ch'i—the universal life force that seamlessly transforms from the dense, physical realm into the ethereal, spiritual world and back again. They watched moisture rise in the heavy river canyons into an ethereal mist, witnessing a literal demonstration of matter sublimating into spirit.

Tao, as the grand, cosmic source of creation is the ‘Way’ that generates and organizes the universe, while Ch’i is the vital energy or material substance of all things that brings the physical world to life.

As an analogy: Tao is like the riverbed—the underlying Way, the natural order and pattern that gives direction to the flow of existence. Ch'i is the water—the vital energy moving through that pattern, nourishing and transforming everything it touches.

Te is the river's distinctive character—the particular way it expresses its nature through its movement and relationship with the landscape. It is sometimes gentle, sometimes forceful, winding around obstacles, nourishing the banks, adapting to the terrain, and ultimately expressing its own nature.

Te isn't simply what the river does; it is how the river naturally is. A river with more boulders will have a different ‘character’ than one with a soft, sandy bottom.

The riverbed gives the water its course, but the water also shapes the riverbed and the flow takes on its own characteristics. Over time, the landscape changes through this interaction. None are entirely separate from the other.

A mountain stream has a different Te from a broad, slow-moving river. One tumbles, rushes, and sings over stones; the other meanders, deepens, and quietly nourishes the landscape. Neither needs to imitate the other. Each expresses its inherent nature.

In the same way, our Te may be inherent, but its expression is shaped and revealed through our encounters with the world. The I Ching offers a way to understand these encounters by illuminating the patterns of change at work in our lives.

Through its wisdom, we begin to recognize not only what is happening around us, but what those circumstances are calling forth within us. It teaches us to recognize the natural movement of change and respond in ways that allow our inherent nature or authenticity to unfold.

Yin and Yang

Like binary code, the lines of the I Ching can appear open (- -) as Yin, or closed (—) as Yang, in patterns that describe phenomena. The Yin-Yang symbol we see today embodies the outer circle of Tao (the one) enclosing two interlocking, swirling shapes—one black (Yin) and one white (Yang)—representing the fluid harmony of opposites within Tao.

Yin and Yang are the complementary, interconnected dualities of the universe, such as dark and light, passive and active, or cold and hot. Each cannot exist without the other and when one reaches an extreme, it turns back to become the opposite.

We see this in the curved boundary of the Yin-Yang symbol, showing a continuous flow where day turns to night and movement yields to stillness. Crucially, each side contains a small dot of the contrasting color, visually demonstrating that nothing is absolute; the seed of one always exists inside the other, emphasizing that balance, interdependence, and constant change are the ultimate laws of the universe.

Like force and field, these foundational concepts at the root of the I Ching show how the dynamic tension between Yin and Yang fuels the universal cycles of change.

The I Ching and Ba Gua

The I Ching is an ancient Chinese philosophical text that describes 64 variations of these Yin and Yang lines. The 64 hexagrams pair two of eight fundamental trigrams, called Ba Gua—each representing a primal force in the natural world. The Ba Gua consist of three lines, while the hexagrams each have six lines.

From these eight Ba Gua, we can dig deeper into the roots of the I Ching to uncover a philosophy based on nature. This may be why this book has become a popular tool for nature enthusiasts seeking inspiration for personal transformation.

64 Hexagrams - six lines that offer insight about the changes we are facing.

8 Ba Gua - primary trigrams composed of three lines that are paired to create the hexagrams.

Just as the I Ching captures the cyclical changes we observe in the seasons, we too, transform in the mirror of nature’s movement toward change.

By examining the eight primary trigrams (Ba Gua) using the sequence pioneered by the Song Dynasty philosopher Shao Yong, we can follow the binary evolution from pure Yin to pure Yang and back again.

The trigram portrayed with all Yang lines is Qián the Creative, representing the ethereal or spiritual because it is pure mind. The trigram with all Yin lines is K'un the Earth, and embodies the physical because it is pure density. These two concepts allow us to recognize the energy behind the Yin and Yang lines as they transform to create the 64 hexagrams.

Because there was no hard barrier between the physical and the metaphysical, the ancients understood the lightning strike of the trigram Zhèn as an act of Heaven’s fertilization, awakening the Earth’s sleeping seeds and sparking the dynamic, seasonal cycle of rebirth.

Shao Yong believed that the human mind and the universe shared the exact same mathematical structure. If you understood the numbers behind the elemental Ba Gua, you could understand the mind of nature.

His organization of the I Ching hexagrams into a binary sequence was later discovered by Leibniz, validating and refining his own development of binary code that became the language of modern computers.

Ch’i and the Ba Gua

We can follow a sequence charting the exact line-by-line evolution of Ch'i as it sublimates into pure spirit and returns.

Kūn (☷) Earth: As three Yin lines, the journey begins in the absolute stillness of pure, receptive matter, offering a dark, nourishing womb where the dense Ch'i rests in complete potential. It is the heaviest, most compressed state of matter. It isn't ‘barren’ in the sense of being dead; it is barren in the sense of being completely uncarved, dormant stone and cold soil. It is the absolute zero of vibration—pure, silent mass waiting to be animated.

Zhèn (☳) Thunder: A Yang line takes root as this dormant matrix receives its first Creative spark, forcefully fracturing the heavy winter crust, and taking form below. This jars the sleeping Earth into motion, where the fracture also allows Ch’i to move upward to create new life.

Li (☲) Fire: The spark of two Yang lines catches hold and surrounds an open Yin line. This ignites a bright, radiating flame of active consciousness and intellect, where Ch’i also warms the growing world. As manifestation, Yin is potential held within, while the Creative surrounds it and gives it expression.

Dui (☱) Lake: The Yang energy from below pushes Yin to the surface as Ch’i spreads out onto a tranquil, joyful plane, allowing the inner brilliance to reflect perfectly across the physical waters of the world. The surface is soft, flexible and completely open to the potentials around it.

Qián (☰) Heaven: A final Yang line eliminates the last of the Yin, reaching the absolute apex of the binary climb. All material density completely vanishes into pure, unyielding cosmic spirit and limitless creative blueprint. Ch'i is at its absolute peak of pure, unformed energy in this trigram.

Xun (☴) Wind: The cycle has officially passed its peak with a newly emerging Yin line below. This will begin a process of condensation, turning inward, and conserving its essence. The pure celestial energy above will begin its descent, transforming into a subtle, gentle breath that persistently penetrates the environment to anchor life. It pulls Ch'i downward into the roots to begin the quiet work of conservation and future regeneration.

Kǎn (☵) Water: As the cosmic clock ticks from Xun to Kǎn, the light doesn't get pushed out from below—the sky itself darkens as Yin. The energy condenses into a treacherous paradox, locking Ch’i as a single line of pure Yang light inside two suffocating walls of heavy material Yin. This is the archetype of the abyss or water—it looks soft, adaptable, and yielding on the outside, but it hides a massive, heavy, and potentially crushing force at its core. Since the spiritual Ch'i is trapped inside the physical Ch'i, it portrays survival of the life force in the dark depths of winter.

Gèn (☶) Mountain: Finally, the last Yang or spiritual Ch’i is forced to the absolute summit, resting atop two heavy layers of crushing material Yin. This is the archetype of the mountain—a massive, dense physical base holding a single line of light at its peak. It marks the ultimate boundary where all movement comes to a total standstill. Like a mist clinging to the highest summit of a mountain right before it evaporates completely into the sky, the line will transform into Yin, collapsing back into the unformed darkness of K'un—and the cycle repeats.

The eight Ba Gua offer more than a static system of symbols or a simple map of nature; it is a profound geometric blueprint of reality itself. By organizing existence into its eight foundational archetypes, they reveal that everything from a solid, silent Mountain to a sweeping Wind, or a violent crack of spring Thunder, is not a collection of separate, disconnected phenomena. Instead, they are simply different densities, configurations, and vibrational states of the exact same underlying life force: Ch'i.

Transformation Through the Ba Gua

Reading the lines as they transform from the bottom up and back again offers inspiration on how your Te, ‘original sincerity’ or authenticity emerge from the forces that shape you. As stages of transformation, life unmasks you while time strips away what you are not.

Kūn (☷) — The Earth / Gestation / Submission

The Lines: All Yin (Three broken lines)

The Lesson: Kūn is a snapshot of the Earth during Winter, when Spring and Summer’s wonderous display returns to a blank canvas. From the final trigram of Gèn, the Mountain, the top Yang line transforms into Yin. In Kūn, the Earth, we are coaxed into a time of turning inward to practice receptivity and submission. We can visualize the Earth during deep Winter darkness, cultivating seeds by fortifying Te.

By emulating the valley, we remain lowly, attracting energy much like gravity. Kūn provides a lesson about how to approach life with complete openness where rigid boundaries disappear. You are invited to reside in this pure, quiet space while you prepare for the spark that will ignite your Te.

Zhèn (☳) — The Thunder / Awakening / Excitation

The Lines: Two broken lines above a solid line (Solid, Broken, Broken)

The Lesson: Zhèn is the shocking Thunder of early Spring storms, believed to animate the sleeping seeds. As the bottom line transforms into Yang, the creative spark emerges deep within the Earth. Two upper Yin lines remain open, acting as an unblocked pathway for upward growth. The spark of life surges forward effortlessly without resistance.

Even while meeting the unexpected, you can feel Te, or the bubbling of instinct taking form within you. Zhèn invites you to approach the unknown to discover the necessary awakening that leads to internal transformation. The unpredictable ignites the inner world, where you give life to the sleeping seeds that inspire your blossoming.

Li (☲) — The Fire / Synergy / Clinging

The Lines: Yang on the outside, Yin in the middle (Solid, Broken, Solid)

The Lesson: Li can be viewed as the synergy of Te, the inner vision or blueprint all species tap in their expression. We may see many similar green shoots during Spring, but each will unfurl as a unique expression of design and color. The top line transforms into Yang where two Yang lines surround one Yin line in collaborative inner and outer radiance. Fire cannot exist on its own; it must cling to wood or fuel to burn. Like passion, this represents the intense relationship where energy anchors itself to what sustains it.

Synergy can be the inner work required to change events, or the need to let go of what you cling to. Li invites you to see that what appears hard around you as a reflection of your inner world. If you want to change circumstances, you must first change your inner world. This internal shift makes the outer world magically transform.

Dui (☱) — The Lake / Joyous / Anchored Depth

The Lines: Two Yang lines below, Yin on top (Solid, Solid, Broken)

The Teaching: At the height of Summer, we observe nature’s flow, where flowers are anchored to their roots, and pollinators follow their instincts. Yin moves upward, while two Yang lines appear below embodying a heart filled like a Joyous lake. While the surface (top Yin line) can be easily rippled, chaotic, or influenced by outside winds, the deep foundation is composed of two solid Yang lines.

This portrays how authenticity remains completely stable and anchored, regardless of events. Dui coaxes you to anchor to your center to cultivate the type of Joy that is undisturbed by the changing landscape around you, where nothing anyone says or does can make or break your day.

Qián (☰) — The Creative / Empowerment / Action

The Lines: All Yang (Three solid lines)

The Teaching: Qián is the apex of the Creative spark after the germination and display have exhausted physical form. Another Yang line pushes upward to transform the top line from Yin to Yang. Three solid Yang lines portray the ultimate energy of the creative force of Tao that initiates, moves, and sustains all things.

Enormous potential seeks new manifestation and requires taking the steps to put it to use. Invited into the newness of your creative power, assertiveness and empowerment lead you to self-actualize. Qián reminds you that life has been perfecting itself for billions of years. As one of its unique creations, it cannot self-actualize until you too, self-actualize.

Xun (☴) — The Wind / Gentle Penetration / Persistence

The Lines: Bottom line Yin, two solid lines above (Broken, Solid, Solid)

The Teaching: Xun is like the Autumn wind that tugs old growth from the branches of trees. As the bottom line opens to Yin, it embodies the gentle and persistent Wind, and inspires the idea of how consistent penetration can chisel a mountain. We can imagine how consistency is given form, like a plant growing from a tiny crack in the rocks.

You are invited to persevere through perceived obstacles by holding to your inner vision. The ups and downs of life are like the trough of a wave. If you are persistent even when the work feels lowly, in time, you will be lifted up. Xun offers inspiration in the way wind and water transform even the hardest of substances. Through your efforts, a dedication to your original sincerity is no match for any obstacle.

Kǎn (☵) — The Abyss / Release / Flow

The Lines: Yin on the outside, Yang in the middle (Broken, Solid, Broken)

The Teaching: Kǎn embodies how Winter storms begin transforming a barren landscape after the leaves have been stripped from the trees. Across the Earth, what appears as decay is actually the ingredients for future life. The top line opens and two Yin lines surround one powerful Yang line. Associated with an ‘abyss,’ this is an image of how inner strength and flexibility in your approach connect you to your Te during crisis.

Change can be unexpected and appear frightening, but the Abyss is the flip-side of Li, the fire. In Li, we follow our inner blueprint, but Kǎn shows how the outer world also unmasks us. The external world feels turbulent or unformed (outer Yin lines), but this outer pressure acts as a catalyst. It coaxes your inner, unyielding strength (the center Yang line) toward an even deeper expression as you flow with life. Kǎn invites you to let go so you can discover that you are the guest not the host. Trust where life is leading you as you open to the flow of the Great River.

Gèn (☶) — The Mountain / Sculpted Silence / Emergence

The Lines: Two Yin lines below, Yang on top (Broken, Broken, Solid)

The Teaching: Gèn is an image of a Mountain, or how the Earth conserves snow for the coming Spring. It is the power that resides in stillness where silence develops inner rectitude. A bottom Yin line forces the middle Yang line to the top, embodying how an inner openness and acquiescing to the flow give us the appearance of something majestic, like a Mountain.

Keeping still, while growing in stature, the Mountain is groomed, shaped, and sculpted by the movement of the elements around it. You too are unmasked by the vicissitudes you meet on the path. The mountain is not trying to become a mountain. Time, pressure, ice, wind, and water participate in revealing its form. Being unveiled by silence suggests that authenticity doesn't have to be constructed or pursued. Gèn invites you to explore the vast openness of a stable, perfectly silent foundation. Holding only to your Te, open to how life weathers you, and how stillness unmasks you.

A Flawless Loop of Opposites

Just as the physical world is created by movement of opposite forces and spinning molecules, we recognize that stagnation arises if left without the constant prodding of oppositional energy.

Qián sits at the Summer Solstice, while K'un sits at the Winter Solstice. Qián is pure energy unformed before it touches matter, while its opposite K’un, is the uncarved soil and denseness of mass.

Xun is the Gentle Wind in its penetrating efforts to return the seeds to the earth, while Zhèn or Thunder, awakens these sleeping seeds. At one pole, we find the small efforts that tug the seeds to the ground in Autumn. At the other end, we see the shocking energy of storms that return life during Spring.

Dui, the Joyous Lake of Summer is a picture of life in its spectacular display. Its opposite Gèn, the Mountain of Keeping Still reflects Winter, when life’s energy turns inward to regenerate. This energy will gather beneath the landscape, as if contemplating the shape of the year to come.

Finally, the drive for expression following the synchronistic intelligence of Li or Fire leads the seedlings toward actualization. It’s opposite, Kǎn the mysterious or Abysmal Water, demonstrates the importance of not fighting what you can’t control—it may be exactly what is needed to give expression to your inner light and authenticity. In the mysteries of the Abysmal, we sacrifice the known for the promise of rebirth.

A Deeper Dive into Kǎn

It is interesting to note that Kǎn, the ‘Abysmal Water’ trigram coincides with a time when all of last year’s growth has disappeared. In many cultures, this is the time of year to honor the dead as if some mysterious cycle was detected that allowed for an opening between two realms.

To a Bronze Age Chinese agrarian or an early Taoist hermit, a Kǎn was literally a deep hole in the ground, a ditch, a ravine, or a sacrificial pit. It represents a landscape where the flat, safe earth suddenly drops out from beneath our feet.

The danger of Kǎn is not the water itself; it is the peril of falling in without noticing. Water is associated with it because water naturally runs downward, pooling and trapping itself in the lowest, darkest trenches of the earth.

As a metaphysical ‘abyss,’ it is the soul locked up inside the physical body and can represent the ‘dark night of the soul.’

In Hexagram 29, Danger, the trigram Kǎn is repeated. The Taoists observed that when you fall into an abyss, your natural instinct is to panic, thrash, and fight against the walls, which only exhausts you and causes you to sink deeper. Therefore, the ‘abysmal’ is actually a test of inner truth and absolute alignment.

One survives the pit by filling up and flowing onward. Like dreams of the ocean that portray how we access our unconscious depths, it is not ‘scary water’ but something that gives expression to more inner light.

When you are in the abyss, you must be like water—filling the pit, remaining true to your inner nature, and flowing steadily without losing your essential character.

The trigram Kǎn appears in many of the more difficult Hexagrams, such as 3 Difficult Beginnings, 4 Youthful Folly and 47 Exhaustion. To succeed across all these hexagrams, we adopt the physical properties of water.

Water never fights a rock; it flows around it. Water never loses its identity; whether it is steam, ice, or muddy water, its atomic core remains unchanged. To transform via Kǎn, you must yield outwardly while remaining completely solid and true inwardly.

Whether traced through the shifting seasonal cycles, the symmetrical matrix of cosmic duality, or as a lesson for success and wellness, the Ba Gua beautifully demonstrate how the universe is a singular, living continuum. It is constantly dancing between form and spirit, across nature and humans, and forever flowing through an eternal symphony of change.
