Sui · Following

Move with the times, follow what is good, choose what to follow, and stay true without losing yourself

Judgment and Plain-Language Notes

Sui: Supreme success. Steadfast correctness is beneficial. No blame.

Commentary on the Judgment: “Following: the firm comes and places itself below the yielding; movement with joy is Following. Great success through correctness, without blame. All under Heaven follow the times. Great indeed is the meaning of Following's time!” Commentary on the Image: “Thunder within the lake: Following. At nightfall, the noble person enters indoors to rest.” The Judgment explains that the firm willingly takes a lower position than the yielding, allowing movement and mutual joy. The Image uses resting at night to show that following means living with the timing of things rather than agreeing indiscriminately. (Zhouyi, Commentaries on the Judgment and the Image; public domain)

Sui has Zhen below and Dui above, thunder concealed within the lake, symbolizing action responding to joy. Its focus is following the times rather than following casually. The judgment's supreme success, beneficial steadfastness, and no blame affirm adapting to circumstances on the condition of right conduct. The lines repeatedly show trade-offs: attaching to the boy loses the mature man, and attaching to the mature man loses the boy. Following has exclusive costs. The fourth nine even says that gain through following brings misfortune in persistence. Choose the right person and time while preserving your own judgment.

The judgment includes supreme success, beneficial steadfastness, and no blame, giving movement with the times a positive direction, hence the rating: Favorable. Yet the second and third lines show unavoidable trade-offs, and the fourth explicitly warns that gain through following can lead to misfortune if boundaries are lost. The top line's binding also suggests constraint, so this is not the highest rating. This is the app's interpretation of the text, not a guarantee of outcomes.

Do: Observe circumstances, follow a trustworthy direction, and review your choices regularly. Avoid: Blind conformity, constantly shifting positions, or losing your own limits.

Understand This Hexagram Through Its Structure

Dui above, Zhen below: movement underneath, pleasure above — the structure of following.

The lower trigram of Sui is Zhen: a solid first line with two broken above. The upper is Dui: two solid lines with a broken one on top. The first, fourth and fifth lines are solid. This is also the primary hexagram in the lesson-eight worked example: with the first line moving, it becomes Cui.

Zhen is movement and Dui is pleasure. The moving end is below and the willing end above, so the structure reads as following. Note that following is not obedience: the moving force sits in the lower trigram, so what is below moves first and what is above goes along. Get the direction wrong and the whole reading inverts.

A teaching example, not a prediction: one team ships something usable first, and others, seeing it, are willing to adopt the same approach. Sui describes that structure; it does not say the approach is correct.

The Six Lines: Original Text and Reflection

Nine at the beginning: One's responsibilities change. Steadfastness brings good fortune. Going out to connect with others brings achievement.

Commentary on the Image: “Responsibilities change; following correctness brings good fortune. Going out to connect brings achievement without losing what matters.” When your role or responsibilities change, following right conduct is fortunate. Success in relationships beyond your door comes from preserving appropriate limits. (Zhouyi, Commentary on the Image; public domain)

When your responsibilities change, you need not cling to the old form. Adjust according to right conduct, and go beyond your original circle to connect with others; this can bring accomplishment.

When duties or responsibilities change, first confirm whether the new direction is reasonable, adapt your methods, and proactively contact unfamiliar people and departments.

Are you resisting the current change, or have you seen what it asks you to adjust?

Six in the second place: Bound to the boy, one loses the mature man.

Commentary on the Image: “Bound to the boy: one cannot join both.” Attaching to the boy loses the mature man; the Image explicitly says both cannot be kept. The point is the exclusivity of following, rather than ranking the people involved. (Zhouyi, Commentary on the Image; public domain)

Tying your attention to one side loses the other. This line directly states that you cannot follow both ways; choice itself carries a cost.

If you are trying to please two opposing people or proposals, acknowledge that both cannot be satisfied. Choose according to your real standards and explain the trade-off.

Which two things are you currently attached to, and which is already due to be released?

Six in the third place: Bound to the mature man, one loses the boy. In following, seeking brings benefit. Dwell in steadfast correctness.

Commentary on the Image: “Bound to the mature man: the purpose leaves what is below.” Choosing the mature man means leaving the boy behind. The line adds that even when following fulfills a wish and brings benefit, one must still dwell in steadfast correctness. (Zhouyi, Commentary on the Image; public domain)

Choosing the more substantial side means letting the other go. Even if this brings gains, remain grounded in right conduct rather than letting desire replace principle.

When directing resources toward a more important person or project, clearly address the side being left behind and check whether benefits alone are driving your following.

In following this time, do you value the other party's rightness, or the benefits you can obtain?

Nine in the fourth place: Following brings gain. Persistence brings misfortune. With sincerity on the Way and clear understanding, what blame can there be?

Commentary on the Image: “Gain through following is, in meaning, unfortunate. Sincerity on the Way makes one's achievement clear.” Gain exceeds one's proper share and is judged dangerous. Only sincerity aligned with right conduct and clear understanding can avoid blame. (Zhouyi, Commentary on the Image; public domain)

Following brings benefits, yet the line explicitly calls this unfortunate because gain can tempt people beyond their proper boundaries. Only sincerity, right conduct, and a clear sense of limits prevent fault.

When following a person or team brings extra benefits, explain their source and allocation proactively so the gains do not become leverage against you later.

Which gains from this association can you fully explain in the open?

Nine in the fifth place: Sincerity toward what is good. Good fortune.

Commentary on the Image: “Sincerity toward the good brings good fortune because the position is correct and central.” Honesty directed toward good undertakings brings fortune, grounded in an upright and impartial position. (Zhouyi, Commentary on the Image; public domain)

Direct sincerity toward good people and undertakings, with the right direction and attitude, and there is good fortune. This line has the most suitable object of following in the hexagram.

After confirming that the other party's goals and methods withstand scrutiny, invest trust and relate honestly without repeatedly holding back.

Does the person or undertaking you entrust with your sincerity meet your own standards?

Six at the top: Detain and bind them, then follow and tether them. The king makes offerings at the Western Mountain.

Commentary on the Image: “Detaining and binding: the upper position has reached exhaustion.” Confinement and binding mark an extreme. The king's offering at the Western Mountain describes ancient ritual, not a direct instruction for modern action. (Zhouyi, Commentary on the Image; public domain)

Following reaches its extreme and becomes bondage: detained and tied, there is no room to advance. The closing ritual account suggests concluding the situation with sincerity and reverence.

When a relationship or collaboration becomes mutual bondage and no one can move, stop expanding it. Address its conclusion through sincere communication rather than increasing your commitment.

Do you still have choices in what you follow, or has it become a bond you cannot leave?

Gui Mei · The Marrying Maiden (Correct) : Correct. Dui below and Zhen above form Hexagram 54, Gui Mei.

Cuì · Gathering : Cui results from changing the first line: a changing line rather than a trigram exchange.

Gǔ · Repairing What Has Decayed : Gu has Xun below and Gen above, so both trigrams differ.
