Line 4 九四
貞吉，悔亡；震用伐鬼方，三年有賞于大國。
The fourth NINE, undivided, shows its subject by firm correctness obtaining good fortune, so that all occasion for repentance disappears. Let him stir himself up, as if he were invading the Demon region, where for three years rewards will come to him (and his troops) from the great kingdom.

In the received Zhouyi text, line 4 of hexagram 64 is a strong (yang) line occupying the fourth line, risen into the upper trigram. The classical line statement — 貞吉，悔亡；震用伐鬼方，三年有賞于大國。 — is what commentators from the Ten Wings onward have read as the figure's own commentary on this one position. James Legge's 1882 rendering, quoted above, keeps the imagery of the original: each line of a hexagram is read as a stage of the same picture, and this page collects the source text for that stage. If you treat the line as moving in the traditional way, flipping it alone produces the changed hexagram linked above; readers have long used that pair of figures to compare a situation as given with the same situation one line different. As always with classical divination texts, this is presented for cultural and reference interest — the text itself carries no prediction about any modern reader's situation.
Questions About Hexagram 64 Line 4
What does line 4 of hexagram 64 say?
The received text reads: 貞吉，悔亡；震用伐鬼方，三年有賞于大國。 In James Legge's 1882 translation: “The fourth NINE, undivided, shows its subject by firm correctness obtaining good fortune, so that all occasion for repentance disappears. Let him stir himself up, as if he were invading the Demon region, where for three years rewards will come to him (and his troops) from the great kingdom.”
Which hexagram does line 4 change hexagram 64 into?
Changing only line 4 of hexagram 64 (未濟, “Not Yet Fording”) gives hexagram 4 — 蒙 (méng, “Enveloping”). This is the classical way a changed hexagram is derived from moving lines.
Are line pages available for every hexagram?
Yes. Every one of the 64 hexagrams now has six line pages — one per line from the bottom line up to the top line — each with the classical Chinese text, Legge's 1882 translation, and the changed hexagram that line produces when it moves.
