Yi · Nourishment

Watch what feeds you, and watch what you feed.

Judgment and Plain-Language Notes

Yi: Steadfastness brings good fortune. Observe nourishment; seek sustenance for your own mouth.

The Tuan commentary says nourishment brings good fortune when what is nourished is correct: observe what a person nourishes, and how they nourish themselves. The Xiang image is thunder beneath the mountain, with the noble person guarding their speech and moderating what they eat.

Gen above, Zhen below. A solid line at top and bottom with four open lines between makes the shape of an open mouth, which gives the hexagram its sense of feeding and sustaining. The commentary puts the weight on nourishing correctly: the question is not whether you are fed but by what, and how. The image narrows it to two habits of the same mouth, speech and food, and asks for restraint in both. The judgement says to seek your own sustenance. Several lines show the opposite, going wrong through envy or through feeding against the grain of things.

Although the judgment gives good fortune through steadfastness, this depends on nourishing what is right. The first nine brings misfortune, the second misfortune in advancing, and the third misfortune in persistence with a ten-year prohibition on action. Adverse lines are numerous, and the fifth also forbids crossing the great river, hence the overall rating: Neutral rather than Favorable. This is the app's interpretation of the text, not a guarantee of outcomes.

Worth doing: moderate your speech and your appetite, and choose sources that genuinely sustain you. Avoid: being led by appetite or by flattery, or settling into long dependence on someone else's provision.

Understand This Hexagram Through Its Structure

Gen above, Zhen below: solid lines only at the top and bottom, with four broken between.

The lower trigram of Yi is Zhen: a solid first line with two broken above. The upper is Gen: two broken lines with a solid sixth. Only the first and sixth lines are solid; the four between them are broken, so two solid lines enclose an empty middle.

The two solid lines read as upper and lower jaws with a gap between, so this hexagram is taken as a mouth and concerns nourishment. Its question is not how much is taken in but where it comes from and who decides. Structurally movement is below and stopping above, so what is needed must be gone after rather than waited for.

A teaching example, not a prediction: someone decides to choose their own learning material instead of waiting for the company to schedule training. Yi describes that structure of choosing one's own intake; it does not say they learn faster.

The Six Lines: Original Text and Reflection

Nine at the beginning: Leaving your sacred tortoise, you watch my moving jaws. Misfortune.

You set aside your own sacred tortoise and watch another's jaw working with envy. The Xiang commentary says plainly that such an attitude deserves no regard.

You leave your own valuable gift unused and look longingly at what someone else is eating. The fault is in abandoning yourself in favour of admiring another.

Rather than measuring yourself against other people's pay and results, take inventory of what you already have and have not yet used. That is the part you can actually act on.

Which of your own abilities have you left idle because you take it for granted?

Six in the second place: Upside-down nourishment, contrary to the constant way; seeking nourishment on the hill. Advancing brings misfortune.

Nourishment sought upside down, against the usual order, reaching to the high mound. The Xiang commentary says such movement loses its proper kind, so advancing brings trouble.

The order of who provides for whom has been inverted, and support is sought upward against the normal pattern. Both the source and the method are unsuitable, so pressing forward goes badly.

When you need support, ask through the channel that fits. Going over someone's head or around them usually damages the relationship and costs you your standing too.

Has the way you are asking for help skipped the person you should have spoken to first?

Six in the third place: Turning against nourishment. Persistence brings misfortune. Do not act for ten years. Nothing is beneficial.

Nourishment turned against itself. The Xiang commentary says the way has been deeply violated, which is why the text calls for ten years of no undertaking.

The proper way of sustaining body and character has been broken. Even holding steady goes badly, nothing is to be undertaken for a long stretch, and there is no advantage. This is the heaviest warning in the hexagram.

If you have been draining yourself or others in the same wrong way for a long time, what is needed is a real change of direction and a long repair, not a different technique for carrying on.

What have you kept doing for a long time, knowing it was wearing you down?

Six in the fourth place: Upside-down nourishment brings good fortune. Watching intently like a tiger, desire following desire. No blame.

Nourishment sought upside down again, but here it turns out well: the Xiang commentary credits light given from above. The tiger's fixed gaze and unbroken desire depict sustained focus, so there is no fault.

Seeking support upward works this time because the support is genuinely being offered. The steady gaze and the continuing want are signs of concentration, and that is what keeps the line clear of fault.

When backing really exists, pressing actively for resources is not overreach. What matters is a clear aim and sustained effort rather than asking in bursts and going quiet.

Have you pursued what you want steadily enough for anyone to notice?

Six in the fifth place: Contrary to the constant way. Remaining steadfast brings good fortune. Do not cross the great river.

The usual order is departed from, yet remaining settled and correct brings good fortune. The Xiang commentary attributes this to yielding compliance with the one above. Strength is short, so the great water is not to be crossed.

The situation is already off the normal pattern. Holding your place without rash movement is what goes well, and the text says outright not to cross the great water. You can hold; you cannot advance.

When your resources fall short, keep the current position and rely on support you trust. This is not the moment to launch something that demands a great deal.

Can your present resources really carry the big thing you want to start?

Nine at the top: The source of nourishment. Danger and good fortune. It is beneficial to cross the great river.

All nourishment proceeds from here. The weight of the role brings danger, and watchfulness turns it to good fortune; the Xiang commentary calls this great cause for celebration.

Everyone's sustenance flows through this position. Height and responsibility bring exposure, and it is precisely the caution that makes it favourable, and that makes crossing the great water suitable.

When other people depend on you, the responsibility itself is the pressure. Staying alert rather than comfortable is what lets you hold the role.

Who is relying on you right now, and what have you put in place for them?

Quick Quiz

Which two lines of Yi are solid?
  • The first and the sixth
  • The third and the fourth
  • The second and the fifth
View answers and explanations for every option

The first and sixth lines (Correct) : Correct. Four broken lines occupy the middle, with one solid line at each end.

The third and the fourth : Those positions are at the boundary; Yi's third and fourth lines are both broken.

The second and the fifth : Those are the centers of the two trigrams; both positions in Yi are broken.

Why is the figure of Yi read as a mouth?
  • A solid line at each end reads as jaws, with a gap between
  • Because the name contains the character for mouth
  • Because the upper trigram is Li
View answers and explanations for every option

The solid lines at top and bottom resemble jaws, with an empty space between (Correct) : Correct. This image comes from the arrangement, rather than the literal meaning of the name.

Because the name contains the character for mouth : The image comes from the lines' arrangement, not the written character's shape.

Because the upper trigram is Li : Yi's upper trigram is Gen.

What does the structure of Yi suggest about how things are obtained?
  • Movement is below: one has to go after it
  • Waiting to be fed is enough
  • It is entirely decided from above
View answers and explanations for every option

Movement is below; you must reach for it yourself (Correct) : Correct. Lower Zhen means movement; upper Gen means stopping.

Waiting to be fed is enough : The moving line belongs to the lower trigram, not the upper.

It is entirely decided from above : The upper trigram means stopping, not giving.
