Zhouyi I Ching, Hexagram 10, the Treading Hexagram, Heaven over Lake, Qian above Dui below

Detailed explanation of the initial nine line of Zhouyi Hexagram Ten
Statement of the First Nine line
Initial Nine: Treading simply; going forward, there is no blame.
The Image says: Going forward with simple treading means carrying out one’s own aspiration alone.
Explanation in plain language
Initial Nine: Conduct yourself with a plain and frank attitude, and there will be no disaster.
The Image Commentary says: Conducting oneself with a plain and frank attitude means being able to follow one’s own aspiration independently.
Explanation by Shao Yong, a Northern Song scholar of the Changes
Neutral: Those who receive this line will see their plans succeed and their wealth increase day by day. Officials who cultivate virtue and preserve their health will have opportunities for promotion.
Interpretation by Fu Peirong, a Taiwanese master of traditional Chinese learning
Timing: Wait for the right moment; achievement will come naturally.
Wealth: Safeguard the old enterprise; in time, profit will surely come.
Household: Auspicious household affairs.
Health: Jogging is beneficial.

Transformation of the First Nine line

When the initial nine line changes, it becomes Zhouyi Hexagram 6: Conflict, Heaven over Water. This is a contrasting hexagram, with Kan below and Qian above, layered together. It is opposite to the Need hexagram and forms an inverse pair with it. Qian represents firmness and vigor; Kan represents danger and entrapment. Firmness with danger, vigor with danger—opposing one another, they inevitably produce dispute and litigation. Dispute is not a good thing, so one must be particularly cautious and vigilant.

Philosophical meaning of the initial nine line:

Su means “plain and unadorned,” and also “holding fast to one’s original nature.” Lu means shoes, and also going out on a journey. Therefore, “simple treading” has two corresponding meanings. First, plain shoes, standing for one’s social status; Xun Shuang said, “Those who tread simply are scholars in common cloth.” Second, plain conduct: walking straight, holding fast to one’s principles, acting according to one’s nature, and symbolizing upright and pure behavior.
From the hexagram image, the initial nine is a yang line in a firm position, at the lowest place. It symbolizes someone talented who is nevertheless willing to remain content in a low position. This is the first step forward; the person has not yet been tempted by wealth and honor, and still advances according to his usual aspiration, so he will have no fault.
The Image says: Going forward with simple treading means carrying out one’s own aspiration independently. Here, “alone” means standing apart and acting independently, not following worldly customs, pursuing one’s aspiration alone—not acting for profit. This line teaches that when realizing ideals and fulfilling responsibilities, one should remain true to one’s original intention, stand independently, and avoid going along with corruption.
Those who receive this hexagram may act according to their own aspirations in dealing with people and handling affairs, without seeking any benefit. It is like a newly graduated student: although very capable, having just entered the workforce, they must begin from the bottom. They should not worry about immediate gains and losses or be moved by external temptations, but independently uphold ordinary principles and lay a foundation for future development.

From the hexagram image, the nine second line is in the middle of the lower trigram, moving along the straight path through the center and handling affairs with real ability. Yet it is a yang line in a yin position, so it is improperly placed. Its situation may be described as advancement meeting obstacles and forceful action bringing worry. It is auspicious to preserve one’s aspiration in seclusion. Seclusion does not mean doing nothing, but deeply tempering oneself and continually increasing one’s abilities.
The Image says: “The secluded person is steadfast and auspicious”; inwardly, they do not throw themselves into disorder. This means that a person living in seclusion can gain good fortune, showing that their heart remains calm and natural, wholly unconfused, and their conviction to act according to ritual is firm.
Those who receive this hexagram may be in circumstances unfavorable to them, unable to display their talents or fully exercise their abilities. Yet they can use this opportunity to temper themselves. For example, when the Qing merchant Hu Xueyan was young, he was dismissed and sent home for helping a friend. With nothing to do, he began practicing the abacus and learning bookkeeping. In this way he laid a foundation for later development. Those who receive this hexagram can use the opportunity to study, cultivate themselves, and strengthen their abilities.
The nine second and nine fifth lines do not correspond, so the second line cannot obtain the fifth line’s support. Yet it can remain centered and upright, and plan its actions in advance; although improperly placed, it will still be auspicious. It walks openly along a level road, while inwardly it has already considered thoroughly how to respond to every kind of danger—how could this not be auspicious? This is like Napoleon’s statement that a qualified commander should always consider solutions for unexpected events. This extraordinary military genius developed the habit of strategic planning in ordinary times, which enabled him to become a commander who was nearly always victorious.
The “nine second” is firm yang in the center, like an open-hearted recluse. It holds to purity and correctness, does not seek fame or distinction, and is not disturbed by worldly affairs; naturally, this is auspicious.

Detailed explanation of the nine second line of Zhouyi Hexagram Ten
Statement of the Second Nine line
Nine Second: The road underfoot is broad and level; the secluded person is steadfast and auspicious.
The Image says: “The secluded person is steadfast and auspicious”; inwardly, they do not throw themselves into disorder.
Explanation in plain language
Nine Second: The person who walks the road is open-hearted; the person who lives in seclusion repeatedly encounters auspicious signs.
The Image Commentary says: The secluded person preserves purity and correctness because their nature is centered and upright, not confused by worldly customs.
Explanation by Shao Yong, a Northern Song scholar of the Changes
Neutral: Those who receive this line are peaceful and content, cultivating themselves and their character. Officials will show signs of withdrawing safely from office.
Interpretation by Fu Peirong, a Taiwanese master of traditional Chinese learning
Timing: Hold your aspirations high and cultivate yourself through the Way.
Wealth: Prices are stable; there is a little profit.
Household: Examine property carefully; beware of losses.
Health: Take care of your eyes.
Transformation of the Second Nine line

When the nine second line changes, it becomes Zhouyi Hexagram 25: Innocence, Heaven over Thunder. This is a contrasting hexagram, with Zhen below and Qian above, layered together. Qian is heaven, firmness, and vigor; Zhen is thunder, firmness, and movement. Movement combined with vigor, with strong yang flourishing, stirs the human heart and will surely bring gains—but only by following purity and correctness; one must not act recklessly. Without innocence there is no gain; innocence surely brings blessing.

Detailed explanation of the nine third line of Zhouyi Hexagram Ten
Six in the third place line statement
Six Third: With one eye impaired, one can still see; with a lame leg, one can still walk. Treading on a tiger’s tail, it bites the person—misfortune. A warrior acts as the great ruler.
The Image says: Having an impaired eye yet being able to see is insufficient for clarity. Having a lame leg yet being able to walk is insufficient for traveling with others. The danger of being bitten comes from being in an unsuitable position. The warrior acting as the great ruler shows a firm aspiration.
Explanation in plain language
Six Third: Trying to see with a damaged eye and walk with a lame leg is forcing oneself beyond one’s ability, like stepping on a tiger’s tail and ultimately being injured by the tiger. This is dangerous. A warrior usurping state power is likewise dangerous.
The Image Commentary says: Trying to see with a damaged eye means one’s sight is insufficient to distinguish things. Trying to walk with a lame leg means one’s strength is insufficient to travel. The tiger injures the person because the sixth-third line is yin in a yang position, an inappropriate placement. A warrior usurping state power is overstepping and offending the superior, acting from the position of the sixth-third line with the aspiration of the ninth-fifth line; disaster is inevitable.
Explanation by Shao Yong, a Northern Song scholar of the Changes
Misfortune: Those who receive this line will face disputes and the troubles of imprisonment; in severe cases, family destruction and death. Officials may suffer demotion.
Interpretation by Fu Peirong, a Taiwanese master of traditional Chinese learning
Timing: Retreat and hold your ground; rash movement brings misfortune.
Wealth: Others deceive and toy with you; goods cannot be sold.
Household: Matters are obscure and unclear; the small oppresses the great.
Health: Care for your eyes and feet.
Six in the third place changing hexagram

When the Six in the Third Place changes, it transforms into Hexagram 1 of the Zhouyi: Qian, Heaven. This hexagram consists of the same trigram doubled, with Qian below and Qian above. It symbolizes Heaven and represents the dragon—a noble person of virtue and ability. It also symbolizes pure yang, harmony, and strength, indicating prosperity and vigor. The Qian hexagram follows the principle by which all things adapt and transform, using “Origin, Success, Benefit, and Perseverance” as its judgment. It signifies good fortune and the fulfillment of wishes, and teaches people to observe the virtues of the Way of Heaven.

Philosophical meaning of the Third Nine line:

The lesson this sixth-third line teaches is: Do not show off the courage of a mere individual.
From the hexagram image, the sixth-third line is yin in a yang position, improperly placed and not centered. Yin represents weak ability; it should only comply and hold fast, not blindly advance aggressively and follow the yang lines into danger.
Those who receive this hexagram must avoid showing off their strength. They should keep to their proper duty and do only what is within their ability. Nor should they be overly pessimistic: their situation is not yet the worst. It is like having an eye problem but still being able to see, or a leg problem but still being able to walk. At such a time, choose tasks within your ability to avoid danger.
The Six in the Third Place is the only yin line in the Hexagram of Treading, yet its fortune is not as good as that of the only yin line in Lesser Accumulation. Why? First, as a yin line in an odd-numbered place, it is neither properly placed nor central. Second, it rides above two firm lines; being yielding while overriding firmness naturally prevents it from gaining the support of the yang lines below. Thus this Six in the Third Place is like a one-eyed person trying to see, or someone with one crippled leg trying to walk: it cannot go far. Therefore, danger and misfortune result. Although the Six in the Third Place wishes to rule the five yang lines, it is as laughable as a warrior wanting to become the Son of Heaven. This line statement admonishes people that their goals must suit their abilities and the position they occupy; otherwise, they will only bring danger upon themselves.


Detailed explanation of the nine fourth line of Zhouyi Hexagram Ten
Statement of the Fourth Nine line
Nine Fourth: Treading on a tiger’s tail, fearful and cautious; in the end, auspicious.
The Image says: Fearful caution ultimately brings good fortune; the aspiration is carried out.
Explanation in plain language
Nine Fourth: One treads on a tiger’s tail, but knows fear in the face of danger; in the end, it remains auspicious.
The Image Commentary says: Fear and vigilance ultimately lead to good fortune; although one has endured hardship, one’s aspiration is fulfilled.
Explanation by Shao Yong, a Northern Song scholar of the Changes
Neutral: Those who receive this line will face danger and should remain gentle and self-controlled to avoid disaster. Officials show signs of becoming commanders bearing tiger tallies. Scholars will achieve good results.
Interpretation by Fu Peirong, a Taiwanese master of traditional Chinese learning
Timing: Be gentle and sincere; ultimately disaster can be avoided.
Wealth: Do not rush to sell; ultimately you will gain a profit.
Household: Manage the household steadily.
Health: Walk carefully.
Transformation of the Fourth Nine line

When the nine fourth line changes, it becomes Zhouyi Hexagram 61: Inner Truth, Wind over Lake. This is a contrasting hexagram, with Dui below and Xun above, layered together. The original meaning of fu is hatching; the date when an egg hatches is extremely precise, giving it the meaning of trust. The outside is solid and the inside hollow, signifying sincerity within the heart, hence it is called Inner Truth. This is the foundation for conducting oneself in the world.

Philosophical meaning of the Fourth Nine line:

From the hexagram image, the nine fourth line is in the lower position of the upper Qian trigram, immediately beside the ruler’s position at the nine fifth. The nine fourth is a minister close to the ruler, resembling someone following behind a tiger-like ruler. Yet it also displays an extremely submissive and fearful image.
The Image says: “Fearful and cautious, ultimately auspicious”; the aspiration is carried out. This means that although one feels afraid, careful and cautious conduct ultimately brings good fortune, showing that one can fulfill one’s aspiration by proceeding carefully in accordance with ritual.
Those who receive this hexagram in divination should feel as though they are walking on thin ice when handling affairs and dealing with people. By being careful and prudent, they can pass through danger and achieve a complete and satisfactory outcome.
The nine fourth is below the ruler’s nine fifth position, so it may make some mistakes—treading on the tiger’s tail. However, it approaches the matter with fear, recognizes its own faults, reflects inwardly, and acts even more cautiously; therefore, it is ultimately auspicious.
The “nine fourth” is neither centered nor properly placed and is near the ruler, so it faces the danger of treading on a tiger’s tail. But because it occupies a yin position, it can walk behind the tiger in fear and caution, and ultimately will be auspicious.
Detailed explanation of the nine fifth line of Zhouyi Hexagram Ten
Statement of the Fifth Nine line
Nine Fifth: Decisive treading; steadfastness is dangerous.
The Image says: Decisive treading is dangerous even when steadfast; the position is properly occupied.
Explanation in plain language
Nine Fifth: Conduct is hasty and reckless; divination shows danger in carrying it out.
The Image Commentary says: Hasty and reckless conduct shows danger in carrying it out, but the ninth-fifth yang line occupies the central position of the upper trigram, properly placed. Therefore, although dangerous, it is not disastrous.
Explanation by Shao Yong, a Northern Song scholar of the Changes
Misfortune: Those who act restlessly and recklessly will soon encounter calamity; in severe cases, their life may be at risk. Officials may achieve merit so great that it overshadows the ruler and consequently receive no reward.
Interpretation by Fu Peirong, a Taiwanese master of traditional Chinese learning
Timing: The clouds part and the sun appears; do not forget the hardships.
Wealth: Work together in harmony; holding goods back from sale is profitable.
Household: Remain mindful of danger in safety, and peace can be preserved.
Health: Turn from danger to safety.
Transformation of the Fifth Nine line

When the ninth-fifth line changes, it becomes Zhouyi Hexagram 38: Opposition, Fire over Lake. This is a contrasting hexagram, with Dui below and Li above, layered together. Li is fire; Dui is lake. Fire above and lake below oppose one another rather than aiding each other. When things overcome one another, growth arises; in back-and-forth there is no emptiness. All things differ, and where there is difference there is opposition and contradiction. Kui means contradiction.

Philosophical meaning of the Fifth Nine line:
From the hexagram image, the ninth-fifth line is yang in a firm position, centered and upright. It is at the center of the upper Qian trigram, with abundant yang energy. Looking at the hexagram as a whole, no line properly corresponds with it. It is like separate emperors each sitting above others, keeping people thousands of li away. Such arrogance is extremely dangerous.
The Image says: “Decisive treading is dangerous even when steadfast”; the position is properly occupied. This warns people: “Be firm and decisive, but act carefully and guard against danger.” Although one is in an appropriate position, one must not be careless.
This ninth-fifth line is in the ruler’s position. Therefore, those who receive this hexagram may be leaders. But a leader must not act alone or be stubborn and self-willed. In handling affairs, do not rush ahead regardless of consequences. Pushing forward too quickly and decisively may sometimes harm other people’s dignity or interests, and may also prevent one from seeing dangers and traps ahead, leading to trouble.
Those who receive this hexagram should think repeatedly before doing anything. Do not make sudden decisions; acting decisively, rashly, or impatiently will bring danger.
As one honored as the ninth-fifth, if one does not know how to use one’s authority to resolve difficulties, the consequences will certainly be unimaginable. Rather than being forced out, it is better to use “sandals with straps” to improve one’s situation.
The “nine fifth” is centered and upright, firm, decisive, and resolute. Yet being firm in a firm position, acting alone and arbitrarily, makes the future dangerous. Therefore, one must follow ritual while remaining decisive, though even then hardship and danger may be unavoidable.
Detailed explanation of the supreme nine line of Zhouyi Hexagram Ten
Statement of the Top Nine line
Supreme Nine: Examine the path you have trodden and assess the omens; turning back, there is great auspiciousness.
The Image says: Great auspiciousness at the top means there is abundant celebration.
Explanation in plain language
Supreme Nine: Conduct yourself cautiously; consider matters carefully and repeatedly; great auspiciousness.
The Image Commentary says: Great fortune and benefit come because the supreme nine line is at the head of the whole hexagram. This indicates that the person will have an important joyous occasion.
Explanation by Shao Yong, a Northern Song scholar of the Changes
Auspicious: Those who receive this line can gain wealth and profit. Officials should retire and enjoy the blessings of quiet and peace. Diligent scholars can achieve good results.
Interpretation by Fu Peirong, a Taiwanese master of traditional Chinese learning
Timing: Later fortune is smooth; blessings and longevity come together.
Wealth: Business dealings back and forth are all profitable.
Household: A family that accumulates goodness will have abundant blessings afterward.
Health: The natural span of life is limited.
Transformation of the Top Nine line

When the supreme nine line changes, it becomes Zhouyi Hexagram 58: Dui, Lake. This is a same-type hexagram, with Lake below and Lake above, layered together. Lake represents water. Two lakes connect, two waters exchange, above and below harmonize, people unite, friends help one another, and joy arises. Dui means joy. It shares the virtue of firmness and vigor, outwardly embracing gentleness, firmly following the right path, and guiding the people upward.

Philosophical meaning of the Top Nine line:

Interpretation of the line statement for the sixth line of the Lu hexagram
Shi means to inspect and examine. Shi Lu means to review the road one has walked. Kao xiang means to consider comprehensively and carefully. Xuan means repeatedly or returning.
The meaning of this line statement is: Look back at the road you have traveled, carefully examine good and bad fortune and blessings and calamities, and reflect upon yourself; this is auspicious.
From the hexagram image, the supreme nine is a yang line in a yielding position, humble and compliant, with both virtue and talent. It is at the very top of the Lu hexagram, symbolizing a retired founding elder who once served the ruler. It settles peacefully at home, reflects on its experiences, and summarizes its lessons; this is greatly auspicious.
Being able to examine one’s conduct at all times, correct shortcomings, and develop strengths naturally reduces mistakes in life, so it brings good fortune. This is like Confucius saying, “Each day I examine myself three times.” Anyone who can do this will gain greatly and achieve greatly in life. Thus the Image Commentary says, “There is abundant celebration.”
