Da Zhuang · Great Strength

Strength only carries you when it stays inside what is proper.

Judgment and Plain-Language Notes

Da Zhuang: Steadfast correctness is beneficial.

The Tuan commentary says the great is strong here: firmness in motion, hence strength. It then reads the favourable correctness as meaning that the great is precisely the correct, and that through what is correct and great the nature of heaven and earth can be seen. The Xiang image is thunder above heaven, with the noble person refusing to take a single step outside what is proper.

Qian below, Zhen above: thunder rolling above heaven, the image of force at its peak. Strength itself is neither good nor bad. Everything hangs on the two words in the judgement that make correctness the condition. The lines move from strength gathered in the toes and a rash campaign, to a ram butting a fence and catching its horns, then the fence opening and the cart axle holding firm, and finally back into a deadlock with no way forward or back. The same lesson runs through all of it: force used as a battering ram jams, while force used within what is right keeps moving.

The judgment's beneficial steadfastness, the second nine's good fortune, and the fourth's good fortune, vanished regret, and broken fence without entanglement show positive results from correct action. Yet the first nine explicitly warns that rushing ahead brings misfortune, while the third's ram caught by its horns and the top's inability to retreat or advance show forceful collision leading to deadlock. Only hardship bringing fortune offers release. Outcomes vary sharply with adherence to right conduct, hence the rating: Neutral. This is the app's interpretation of the text, not a guarantee of outcomes.

Worth doing: aim your strength at a legitimate goal, and check where the limits sit before you act. Avoid: meeting force with force, displaying what you can do, or mistaking being able to do something for being right to do it.

Understand This Hexagram Through Its Structure

Zhen above, Qian below: four solid lines rising from the base, with movement on top.

The lower trigram of Da Zhuang is Qian, all solid; the upper is Zhen, with a solid fourth line and two broken above. Lines one through four are solid; the top two are broken.

Four solid lines rise from the bottom to the fourth place, and the moving line sits at the top of that run. Structurally this reads as strength: the weight is already sufficient and still rising. The caution attached to this hexagram also comes from its structure — the solid lines are all in the lower part and the two above are yielding, so whether the top can carry that rising strength is a separate question.

A teaching example, not a prediction: a product line has its people and budget in place and is about to scale, while the approval process upstream has not caught up. Da Zhuang describes that structure.

The Six Lines: Original Text and Reflection

Nine at the beginning: Strength in the toes. Advancing brings misfortune. There is sincerity.

The Xiang commentary says that strength gathered in the toes shows a confidence that runs itself out. The base text keeps the older form of the locative particle.

All the force sits in the toes, the lowest point, and the momentum arrives before the standing does. Setting out on a campaign from here does not go well. The confidence is real, but the base under it is too thin to hold.

The urge to expand right after a first result is usually the riskiest moment. Shore up the foundation underneath before deciding how far to travel.

Is your current confidence coming from capability or from momentum?

Nine in the second place: Steadfastness brings good fortune.

The line says only that correctness brings good fortune. The Xiang commentary attributes this to the central position, where strength is neither short nor excessive.

The whole line is two words about holding correct, and that is enough. Standing in the middle position, the strength is balanced, so simply keeping to what is right goes well. Nothing extra is required.

When your state is already right, do not add drama to it. Carrying on steadily by the principles you have set is the best available move.

Is there something in your life that is already good enough just as it is?

Nine in the third place: The petty person uses strength; the noble person uses restraint. Persistence is dangerous. A ram strikes a fence and entangles its horns.

The Xiang commentary contrasts the small-minded person who relies on force with the noble person who declines to. The ram drives its horns into the fence and traps them there, so the one who leans on strength ends up caught.

Two people with the same strength: one spends it proving something, the other chooses not to. Ramming through ends like the ram at the fence, horns stuck, unable to go either way, and the harder it pushes the tighter it holds.

Increasing the force every time you hit an obstacle usually just wedges you in further. Step back half a pace, look at how the thing is actually built, then decide where to go through.

The thing you are forcing right now, is it jamming harder the more you push?

Nine in the fourth place: Steadfastness brings good fortune and regret vanishes. The fence breaks without entanglement. Strength in a great wagon's axle supports.

The Xiang commentary says that with the fence broken open and nothing caught, this is the moment to go on. The line uses the firm axle of a large cart as the figure for ample carrying power.

Holding correct goes well and the regret clears. The fence that was blocking you gives way of itself, so you are no longer stuck. The strength has moved into the axle of a large cart: it carries and travels rather than batters.

When the obstacle loosens, put your energy into the structures that keep things running smoothly, such as process, tooling and people. That is worth more than another demonstration of how strong you are.

Is your effort going into hitting the wall or into repairing the cart?

Six in the fifth place: Losing the sheep with ease. No regret.

The Xiang commentary explains the loss of the sheep in the open borderland by the unsuitability of the position: this kind of hard force was never meant to be held on to here. The base text keeps two older characters in this line.

The sheep is lost on flat open ground and there is no regret. The sheep stands for the combative, hard-charging impulse. The position was never right for forcing anything, so losing it is a release rather than a loss.

Let go of a position you have been defending at real cost. It feels like a loss on the day, and quite often you are relieved later that you stopped spending yourself on it.

Is there something whose loss actually came as a relief?

Six at the top: A ram strikes the fence, unable to retreat or advance. Nothing is beneficial; hardship brings good fortune.

The Xiang commentary says that being unable to retreat or to advance comes from never having looked carefully. Holding correct through the hardship goes well, because the fault does not last long.

The ram's horns are caught in the fence: it cannot back out and it cannot get through, and no reading of it looks good. The way out is to accept how hard it is and work it loose slowly, so the deadlock does not become permanent.

Once you are stuck, stop using the same move harder. Admit the difficulty, extend the timeline, and ease it free piece by piece. That gets you out faster than one violent pull.

Are you willing to admit that this is genuinely hard?

Quick Quiz

Which lines of Da Zhuang are solid?
  • The first through the fourth
  • The first through the third
  • The third through the sixth
View answers and explanations for every option

The first through fourth lines (Correct) : Correct. Lower Qian's three solid lines join upper Zhen's fourth line.

The first through the third : The fourth line is also solid, belonging to upper Zhen.

The third through the sixth : The fifth and sixth lines are broken.

Where does the caution in Da Zhuang come from?
  • The solid lines are all below, and the top two are yielding
  • Because the figure has no moving line
  • Because the upper trigram is Kan
View answers and explanations for every option

Solid lines are concentrated below, with two yielding lines above (Correct) : Correct. Whether those above can receive strength advancing upward is a separate question.

Because the figure has no moving line : Changing lines are cast; they are distinct from the hexagram's own diagram.

Because the upper trigram is Kan : Da Zhuang's upper trigram is Zhen.

Which trigram is the upper half of Da Zhuang?
  • Zhen (one solid below, two broken above)
  • Qian · Heaven (three solid lines)
  • Kun · Earth (three broken lines)
View answers and explanations for every option

Zhen · Thunder (one solid line below, two broken above) (Correct) : Correct. The fourth line is solid; the fifth and sixth broken.

Qian · Heaven (three solid lines) : Qian is Da Zhuang's lower trigram.

Kun · Earth (three broken lines) : The fourth line is solid, so the upper trigram is not Kun.
