I Ching Hexagram 17
Hexagram 17: Sui (随)
Composed of 震 (Zhen) below and 兑 (Dui) above · following · adaptation · attunement · fidelity
The Judgment
随：元亨利贞，无咎。
Sui (Following): great, flowing, favorable, constancy, no blame. The judgment is the standard fourfold formula, and the hexagram rests on the natural image of a thunderclap moving over a lake: the thunder goes on its way, and the lake receives it.
Translation notes
- 随: Wilhelm renders "to follow / following" — The great image decides the meaning here: thunder in the middle of a lake. Thunder moves, the lake does not. So following is neither submission nor imitation — it is the act of adjusting to something already passing through. The same image ends with 向晦入宴息, going in at dusk and resting. Following in this text includes stopping, on a schedule.
- 元亨利贞: Wilhelm renders "primordial success, beneficial, correct and firm" — The same four words open hexagram 1, but they are not interchangeable. In Qian they describe the force itself; in Sui they describe the condition the follower must find — a good beginning is available only to whoever is following something worth following with constancy of their own. Lines 2 and 3 then show the failure: a yin line choosing the smaller, nearer attachment and calling it loyalty.
The judgment above quotes the classical Chinese of the Zhou Yi (public domain); the English gloss and modern reading are our own. Compare with James Legge's The I Ching (Sacred Books of the East, Vol 16) , 1882 (public domain).
Quick Answers
Is hexagram 17 (Sui) good or bad?
One of the twelve auspicious hexagrams, and the least passive of them. The judgment gives all four virtues. But the hexagram is really about the quality of whatever you attach yourself to, so the answer depends on that: line 5, the one that chooses the good, is the whole hexagram in miniature. Its warning is at the top line, where following becomes holding on far too hard.
What does hexagram 17 (Sui) mean in love?
It means you are meant to be responsive rather than fixed — the lake receives the thunder, and that is the image for a working relationship. Partnered, expect the relationship to keep adapting and to need that adaptation done deliberately. Single, it points toward a person or a circle with real direction in it rather than toward a passive wait. And read 六二 as a straight warning: a convenient attachment costs you the larger one.
What happens when line 6 of hexagram 17 (Sui) changes?
Line 6 is 上六, the top line: holding someone bound so firmly they cannot get free. Flip it and Sui becomes Hexagram 25 (Wu Wang, Innocence), and the contrast is the whole point. The rigid holding releases, and what replaces it is either a genuine return to something natural or an abrupt break. Concretely, a possessive phase in a relationship or a job ends — either you let go on your own terms, or the situation removes itself. The text's release is deliberate, not accidental.
The Six Lines
Read your line of interest below. Lines are read from the bottom (line 1) to the top (line 6). A changing line means the hexagram is transforming — see the related hexagrams at the bottom.
初九
官有渝，贞吉。出门交有功。The office has change. Constancy is good fortune. Go out the gate and associate; there is achievement. Changing into Hexagram 45 (Cui, Gathering).
Beginning, and the posture is mobile rather than fixed: if the role or the terms change, adjust and keep the constancy in your conduct rather than in the arrangement, then actually go out and meet people, because the line says that is where the result comes from.
六二
系小子，失丈夫。Bound to the young boy; loses the man. Changing into Hexagram 58 (Dui, Joyous).
A yin line choosing the smaller, easier, nearer attachment and losing access to the larger one — not about age, but about the option you keep when you commit to the convenient thing, and the text does not soften it.
六三
系丈夫，失小子。随有求得，利居贞。Bound to the man; loses the boy. In following there is a seeking and an obtaining. It is favorable to abide in constancy. Changing into Hexagram 49 (Ge, Revolution).
The mirror of line 2 and slightly better, since choosing the larger attachment gets you what you wanted — but note the condition, 利居贞, stay put and hold firm, because getting the thing does not license moving on the strength of having gotten it.
九四
随有获，贞凶。弗过遇之？往有尚。In following there is a gain; constancy is inauspicious. Do not pass it by and meet it? Going there has honor. Changing into Hexagram 3 (Zhun, Difficulty at the Beginning).
The trap line, where a chance to profit by following is exactly what constancy ruins: if something is pulling you along for the benefit, ask whether you have actually met it or merely walked past, and the text's answer is to go and see it properly.
九五
孚于嘉，吉。Trust in what is good. Good fortune. Changing into Hexagram 51 (Zhen, The Arousing).
The best place in this hexagram, where following stops being deference and becomes judgment: the one others can rely on, attached to the good, holding the center, and choosing well is the whole skill.
上六
拘系之，乃从维之。王用亨于西山。Hold him bound, and then bind him also from behind. The king makes his offering at the western mountain. Changing into Hexagram 25 (Wu Wang, Innocence).
At the top following turns into holding on, binding someone so thoroughly they cannot get loose until it has to be ceremonially undone — which is why this is a warning about attachment rather than an endorsement of grip.
Hexagram 17 in Love, Career & Decisions
Love & Relationships
Flexible, and honest about the price. Partnered: the hexagram describes adjusting to each other as the accurate definition of intimacy — the lake takes the thunder. But it names two failure modes plainly, and both are about attachment. 六二 is choosing the easier, smaller bond and losing the larger; 六三 is choosing the larger and then needing to hold still afterwards. Single: the pattern is following something genuinely in motion — a group, a craft, a person with real direction — rather than picking a partner off a static menu. The line to check is 5: whether what you are drawn toward is actually good.
Ask what you have bound yourself to, and whether you would still choose it if it stopped being convenient.
Career & Work
Favorable for adaptation and for joining something already in motion, less so for setting a direction of your own. Answer early: yes to the new team, the restructure, the pivot, the tool your organization has decided on. No to a role where you would be expected to author strategy, because Sui is the following hexagram. Line 3's condition — 利居贞, stay and hold — is the practical warning: get what you came for, then do not move on the strength of having gotten it. Line 4 is the one to fear in an employment context, the promise of gain that comes from attaching yourself to whoever is currently ascending.
Follow a person or a method for a defined stretch, write down what you are learning, and set a date to re-evaluate instead of drifting indefinitely.
Making a Decision
Conditional YES — go if what you are following is worth following. The judgment gives all four virtues, but the lines say the deciding factors are the quality of what you attach to (六五) and the state you will be in afterwards (六三). Watch whether you are drawn by the thing itself or by who is attached to it: line 4 marks the difference between a gain and a trap. If you chose the smaller, safer attachment out of convenience, line 2 says plainly that you lose the larger one.
Favorable if the direction is sound and you can hold still after you arrive — but do not commit to follow something you have not properly looked at.
Health & Wellbeing
Responsive and permeable. Sui's energy is that of the lake, which takes whatever weather arrives, and it is why this period can leave you unusually sensitive to other people's states. The classical pairing is rest at the proper hour, which the text names directly in its great image. That is a good description of the remedy: regularity rather than resistance. For entertainment and reflection only, not medical advice.
Go to bed at the same time for a week, and keep one stretch of the day free of anyone else's mood.
