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 21 噬嗑
亨。利用獄。
Shih Ho indicates successful progress (in the condition of things which it supposes). It will be advantageous to use legal constraints.

The changing lines of hexagram 49
| Line | Chinese | Legge |
|---|---|---|
| 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. |
| 5 | 大人虎變，未占有孚。 | The fifth line, undivided, shows the great man (producing his changes) as the tiger (does when he) changes (his stripes). Before he divines (and proceeds to action), faith has been reposed in him. |
| 6 | 君子豹變，小人革面，征凶，居貞吉。 | The sixth line, divided, shows the superior man producing his changes as the leopard (does when he) changes (his spots), while small men change their faces (and show their obedience). To go forward (now) would lead to evil, but there will be good fortune in abiding firm and correct. |
