What Changing Lines Mean

A line connects two states

A moving line marks a place where the present six-line state changes polarity. The original hexagram remains the starting state; changing every moving line produces the resulting hexagram. That relationship is structural, not a guarantee about a future event.

Positions run upward

Line numbers run from bottom to top. A moving position keeps its line statement in the original hexagram, while the corresponding position in the resulting hexagram shows the changed polarity. Which passage leads depends on the reading protocol.

The Zhu Xi protocol used here

0. With no moving lines, this protocol centers the original Judgment.
1. With one, it centers that original line.
2. With two, both original lines are read and the upper leads.
3. With three, both Judgments are read and the change chart determines which leads.
4. With four, the two unchanged lines in the resulting hexagram are read and the lower leads.
5. With five, the sole unchanged result line leads.
6. When all six move, Qian and Kun use their separate Use Texts; other casts center the resulting Judgment.

Two examples with three moving lines

Read cast codes from the bottom line upward. In 999888, the lower three lines move: Hexagram 11 changes to 2, and the original Judgment leads. In 777666, the upper three move: Hexagram 11 changes to 1, and the resulting Judgment leads. Both cases still read both Judgments. The difference follows the two halves of Zhu Xi’s twenty-case chart for three changing positions; the count alone does not identify the leading passage.

Read the selected passage in its setting

The focus rule chooses where to begin. It does not turn that passage into an isolated slogan. In his Brief Remarks on the Changes, Wang Bi treats a hexagram as a connected situation whose lines acquire meaning within it. Read the selected line beside the original Judgment, then notice what its particular image adds: a blocked road, help arriving, a small gain, or an action carried too far. The resulting figure supplies another context to examine, not a replacement for the words of the selected passage.

One protocol, not a universal rule

IChingAsk follows the method recorded in Zhu Xi's Introduction to the Study of the Changes. It is one influential classical protocol, not the only way readers combine changing-line texts. Here, leads identifies the reading focus without erasing the other visible changes.
