Hexagram 49 革 changing to hexagram 8 比
Changing lines (counted from the bottom): 1, 3, 4.
What to read
Three changing lines: read the judgments of the original and the resulting hexagram; the original is the main one. (Rule set out by Zhu Xi in the Yixue qimeng.)
Judgment of hexagram 49 革
已日乃孚，元亨。利貞。悔亡。
(What takes place as indicated by) Ko is believed in only after it has been accomplished. There will be great progress and success. Advantage will come from being firm and correct. (In that case) occasion for repentance will disappear.
Judgment of hexagram 8 比
吉。原筮元永貞，无咎。不寧方來，後夫凶。
Pî indicates that (under the conditions which it supposes) there is good fortune. But let (the principal party intended in it) re-examine himself, (as if) by divination, whether his virtue be great, unintermitting, and firm. If it be so, there will be no error. Those who have not rest will then come to him; and with those who are (too) late in coming it will be ill.

The changing lines of hexagram 49
| Line | Chinese | Legge |
|---|---|---|
| 1 | 鞏用黃牛之革。 | The first line, undivided, shows its subject (as if he were) bound with the skin of a yellow ox. |
| 3 | 征凶，貞厲，革言三就，有孚。 | The third line, undivided, shows that action taken by its subject will be evil. Though he be firm and correct, his position is perilous. If the change (he contemplates) have been three times fully discussed, he will be believed in. |
| 4 | 悔亡，有孚改命，吉。 | The fourth line, undivided, shows occasion for repentance disappearing (from its subject). Let him be believed in; and though he change (existing) ordinances, there will be good fortune. |
