Hexagram 50, Dǐng (The Cauldron): Meaning, Structure, and Its Six Lines

A dǐng is a bronze cauldron — the three- or four-legged ritual vessel in which early China cooked its offerings and, by extension, held its statecraft together; to "possess the cauldrons" was to hold legitimate power. Hexagram 50, 鼎 Dǐng, the Cauldron is the rare figure the tradition reads as a literal picture: the six lines drawn as an actual pot. That pictorial reading is the fastest way into everything the hexagram means, so it is where this close reading starts — the vessel first, then its judgment, its six lines, and how to read it when you cast it.

A cauldron drawn in six lines

Read the figure as an object standing on the page. The broken bottom line is the divided feet the pot rests on; the three solid lines above it — lines two, three, and four — are the full, heavy belly holding the food; the broken fifth line is the pair of ears cast into the rim; and the solid top line is the carrying-ring slipped through them to lift the whole thing. Beneath that picture sit two trigrams: the lower is ☴, wind and wood, and the upper is ☲, fire — wood feeding a flame, which is precisely a fire built under a pot. Where its partner figure sets water against fire in open conflict, the Cauldron sets wood beneath fire in cooperation: fuel and flame working together to transform what is raw into what can nourish. The classical image reads wood-and-fire as the cauldron and draws from it a lesson of settling into one's place: the noble person takes up a correct position and makes the mandate firm.

Cook the raw, nourish the pillars

After upheaval comes the cauldron. Its judgment is short and unclouded — supreme good fortune, and success — because its work is the constructive one: to build the stable structure that cooks the raw into the nourishing and turns raw talent into load-bearing pillars. The task now is not to tear anything down but to establish the institution, feed the capable, and let a new mandate set into its proper form. The hexagram's essence names both halves of that work at once: cook the new order, and nourish the people who will carry it. A cauldron is never only about the food; it is about the vessel steady enough to make food of what was inedible, and to do it again tomorrow.

Legs, belly, ears, and rings: the six lines

Read from the bottom up, Dǐng's lines climb the vessel from its feet to its handle, and the fortune rises as they go:

• First line — the overturned pot. Tip the cauldron over to empty out the stale dregs before you cook. It is an irregular way to begin, yet a legitimate one: clearing the old residue is the honest first move, not a fault.
• Second line — real substance within. With genuine food in the vessel, the envious may resent you but cannot reach you. Solid worth is its own protection; what is truly full does not need to defend itself.
• Third line — the warped ears. The handles are deformed and the pot cannot be lifted, so its fine contents go untasted — good work stalled for want of a way to move it. The line's counsel is patience: the blockage breaks at last, like long-awaited rain.
• Fourth line — the broken leg. The leg snaps and the prince's meal spills across the floor. This is the hexagram's gravest warning: capacity that fails under real weight disgraces everyone it was meant to feed. Do not accept a load your structure cannot bear.
• Fifth line — yellow ears, metal rings. Ears of yellow and rings of strong metal: receptive at the center yet firm at the grip. This is exactly the balance that lets the vessel be lifted and put to use — the hexagram's most workable line.
• Top line — rings of jade. Carrying-rings of jade, firmness tempered to perfect gentleness. Great good fortune, and nothing this serves fails to prosper: the completed vessel, hard where it must hold and soft where it must yield.

The shape read straight up is a lesson in building anything that must last: empty the old before you fill it, let real substance be its own guard, size the load to the leg, and temper firmness with give at the very top.

The vessel after the fire

The Cauldron is the inverse of Hexagram 49, 革 Gé, Revolution: turn Dǐng completely upside down and Gé is what you get. The two are read as a single pair because they are two ends of one motion — Revolution tears the exhausted order down, and the Cauldron casts a working order into the space it cleared. It is telling that the Cauldron's own first move is to empty its dregs: even building the new begins with a small act of revolution, and even revolution, at its summit, is told to stop burning and consolidate. Dǐng's line-by-line mirror is Hexagram 3, 屯 Zhūn, Difficulty at the Beginning — flip every line of the Cauldron and you reach the birth-pangs of a venture that has no vessel yet, all raw energy and no form to cook it in.

Reading the Cauldron when you cast it

In a cast, structure sets the reading. A still Dǐng with no moving lines counsels a stance: this is a season for building rather than breaking — for establishing the structure, feeding the capable, and settling into a role that lets a new order hold. Ask what in your situation is the pot to be steadied and filled, and whether you have cleared its old dregs before pouring in the new. If lines are moving, let each refine that work: the overturned-pot line blesses emptying first, the broken-leg line warns against a load your capacity cannot carry, the jade-ring line marks firmness softened to just enough give. Several moving lines are weighed, not averaged — a craft the changing-lines guide sets out in full. And keep the register steady throughout: the figure is arranging your attention, not promising a result.

When you are past the tearing-down and facing the harder question of what to build in its place — and whether the structure you have in mind can bear the weight it will carry — bring it to the Six Doors and see whether the cauldron the moment answers with can be lifted, and can hold.
