Xian · Mutual Influence
Meet others with an empty mind and no calculation.
Judgment and Plain-Language Notes
Xian: Success. Steadfast correctness is beneficial. Taking a wife brings good fortune.
The Tuan commentary glosses Xian as influence: the yielding above and the firm below respond to each other, stillness meets pleasure, and the man places himself beneath the woman, which is why the judgement is favourable. Heaven and earth influence each other and all things come to life. The Xiang image is a lake on the mountain, with the noble person receiving others through emptiness.
Gen below, Dui above: a lake resting on the mountain, an image of influence and exchange. The name is the word for feeling with the heart radical removed, which suggests a response that is natural rather than calculated. The judgement speaks of marriage in its original setting, and the core of it is that the stronger party is willing to place themselves lower so that both can genuinely meet. The lines take the body from the ground up, from toe and calf to thigh, back and jaw, and warn that influence has to be proportionate. Rushing, following blindly, or stopping at talk all fall short.
The judgment's success, beneficial steadfastness, and good fortune in marriage are all positive. Its commentary grounds influence in Heaven and Earth's creation of all things, and the fourth nine's good fortune and vanished regret also favor this direction. Yet the second six warns that rash movement is dangerous and staying brings fortune, the third has regret in advancing, and the top reaches only speech. Impatience, blind following, and empty words weaken influence, hence the rating: Highly Favorable, rather than the highest. This is the app's interpretation of the text, not a guarantee of outcomes.
Worth doing: settle yourself before responding to a feeling, and build the exchange on sincerity and respect. Avoid: being pulled along by a passing mood, or trading flattery and pressure for a response.
Understand This Hexagram Through Its Structure
Dui above, Gen below: a mountain beneath a lake — two sides affecting each other.
- Name the upper and lower trigram of Xian.
- Explain why this arrangement reads as mutual influence.
- Work out that Mutual Influence with its halves swapped is Decrease.
The lower trigram of Xian is Gen: two broken lines with a solid third. The upper is Dui: two solid lines with a broken sixth. The third, fourth and fifth lines are solid, so the solid lines of the two trigrams meet on either side of the seam.
Gen is stopping and Dui is pleasure. The stopping end holds still below while the responsive end answers above, and the solid lines of the two halves sit adjacent across the seam, so the figure reads as mutual influence: one side does not move and the other is affected all the same. The hexagram is often used to discuss relationships, but it describes a structure of interaction, not its outcome.
A teaching example, not a prediction: someone simply does their work well and persuades nobody, yet a colleague alongside changes how they work. Xian describes that structure of mutual influence.
The Six Lines: Original Text and Reflection
Six at the beginning: Influence in the big toe.
Influence reaching the big toe. The Xiang commentary says the intent is already turned outward, though nothing has yet been put into action.
The response has only stirred in the toe, the first faint motion of an inclination. The line gives no verdict, which fits: an intention has surfaced and nothing has yet succeeded or gone wrong.
When you first feel drawn to a person or an idea, let it stay in the observing stage. Watch for a while longer before deciding whether to commit.
Do you understand where this new attraction actually comes from?
Six in the second place: Influence in the calf. Misfortune; staying brings good fortune.
Influence reaching the calf. The calf moves first, which makes rash action easy, hence the unfavourable reading; the Xiang commentary says that staying put and yielding does no harm.
The response reaches the calf and the leg wants to move forward at once. That haste carries risk, while staying settled goes well. The difference lies not in the feeling but in whether you act on it immediately.
Declaring yourself, placing the order or switching careers the moment you feel something carries high risk. Staying where you are and letting the feeling settle is usually steadier.
If you hold off for now, will this feeling fade or become clearer?
Nine in the third place: Influence in the thighs, clinging to following. Advancing brings regret.
Influence reaching the thigh, which follows the foot rather than moving of itself. The Xiang commentary says the intent lies in following others and what is held to is too low, so advancing brings regret.
The response reaches the thigh, which can only go where the foot goes. The commentary names the problem directly as an intent set on following others, and advancing that way brings regret because your own judgement is gone.
Moving at other people's pace and doing whatever they do saves effort in the short run and slowly carries you away from the direction you actually wanted.
Is this decision what you want, or what everyone around you is doing?
Nine in the fourth place: Steadfastness brings good fortune and regret vanishes. Restless coming and going; friends follow your thoughts.
Correctness brings good fortune and regret disappears; the Xiang commentary says no harm has yet come from influence. But thoughts coming and going restlessly draw only narrow responses, which it calls not yet broad.
Stay correct and regret dissolves. If your mind swings back and forth in anxious calculation, what answers you will match that same level. The quality of the exchange follows from whether your mind is settled and open.
Constantly guessing what the other person thinks and changing your approach tends to draw an equally unsteady response. Settle your own principles and the relationship steadies more easily.
Is the thought you keep turning over solving the problem or manufacturing anxiety?
Nine in the fifth place: Influence in the back muscles. No regret.
Influence reaching the flesh of the back, which lies behind the heart and does not move at whim. The Xiang commentary says the intent is at the periphery, so the line reaches only absence of regret.
The response reaches the back, which does not dance to the mood, and so there is no regret. The commentary notes that such stillness can also shade into distance, which is why it stops short of good fortune.
Keeping your feelings out of it prevents mistakes, and detaching too far makes people think you do not care. There is still a balance to find between composure and involvement.
Is your calm a mature restraint, or a way of keeping yourself out of it?
Six at the top: Influence in the jaw, cheeks, tongue.
Influence reaching the jaw, cheeks and tongue. The Xiang commentary describes this as an outpouring of talk: words in abundance and sincerity in short supply.
The response stops at the mouth, leaving only verbal warmth. The line gives no verdict, but the commentary makes the point: however much is said, nothing moves anyone unless it is carried out.
A relationship held together by compliments, promises and pleasant phrasing eventually shows through. Doing one thing you said you would carries more weight than saying ten more.
Which promise you made recently have you still not delivered?
