You've made your cast and you have six lines. Now what? A hexagram holds several layers of meaning, and knowing how it's put together helps you read it without getting lost.
Two trigrams, one on top of the other
Every hexagram is made of two trigrams:
- The lower trigram holds lines 1, 2 and 3. It's also called the inner trigram: it speaks of what is inside, close at hand or just beginning.
- The upper trigram holds lines 4, 5 and 6. It's also called the outer trigram: it speaks of what is outside, farther away or further along.
Looking at the two trigrams is often the quickest way into a hexagram. Take Well-Being: heaven is below and earth is above. It looks upside down, but there's a logic to it: heaven tends to rise and earth tends to sink, so in this position they meet. Its image puts it this way: "Heaven and earth join: peace."
Now flip them. In Decline, heaven is above and earth below. Each moves away from the other and they never meet. Same two trigrams, and the order changes the whole meaning.
The six positions
Lines are counted from the bottom up, and each place has its own character. These are the line positions:
- Line 1: the beginning. Something just starting, still hidden.
- Line 2: the center of the lower trigram. A steady, modest place, close to everyday life.
- Line 3: the top edge of the lower trigram. A point of transition, often restless.
- Line 4: the doorway into the upper trigram. Close to whoever is in charge; it calls for care.
- Line 5: the center of the upper trigram. Traditionally the ruler's place, the strongest of all.
- Line 6: the end. Something past its peak, or stepping away.
Tradition adds more nuance: lines 2 and 5 are "central" and tend to be favorable, and odd positions suit yang lines while even positions suit yin ones. You don't need to memorize this to start, but it helps you see why the same yang line says one thing in second place and something else in sixth.
The names of the lines
In the classical text, each line is named by its place and its type. A 9 marks a yang line and a 6 a yin line. For example, 初九 is "nine at the beginning" (a yang line in place 1), 六二 is "six in the second place," and 上九 is "nine at the top." The numbers come from casting: 9 and 6 are the values of changing lines, and tradition uses them to name every line of their kind.
The texts of a hexagram
Each hexagram comes with:
- A name that sums up the situation.
- The judgment, a short text on the moment as a whole. It's the first thing you read.
- The image, which joins the two trigrams in a scene from nature and says how the noble person acts in response.
- The line text for each of the six lines.
Classical editions add ancient commentaries too, such as the Tuan on the judgment and the Small Image on each line.
In the texts you'll meet formulas that keep coming back: "good fortune" and "misfortune", "no fault", "constancy". Think of them as the book's road signs: they tell you whether the way is clear, whether to go carefully, or whether to stop.
Reading a full answer
- Go back to your question. Read it again before you read anything else.
- Read the name and the judgment. In Cambios you'll find the practical layer (what it means for you, now) and the poetic layer (the voice of the old book).
- Look at the trigrams. What's below, close at hand, and what's above? Do they meet or pull apart?
- Read the changing lines, if there are any. They're the most specific part of your answer. The rules for which ones to read are in Moving Lines.
- Read the second hexagram, if changing lines create one. It shows where the situation is heading; see The Relating Hexagram.
- Write down what you see. A sentence or two on what the answer tells you about your question. Rereading them in a few weeks is often revealing.
Don't expect every word to fit. Often a single image or a single sentence is the one that lights up your situation. Hold on to that one.
A short example
Say you ask how to approach a new project and get Activity with the first line changing. The judgment speaks of beginnings and creative strength, but the changing line says: "It's not yet time to act." In the poetic layer: "A dragon under the water. Do not act." Together they tell you something concrete: the energy is there, but still under the water. Get ready, and don't leap yet.
