Hexagram 49 革 changing to hexagram 28 大過
Changing lines (counted from the bottom): 1, 2.
What to read
Two changing lines: read both line texts of the original hexagram; the upper one is the main one. (Rule set out by Zhu Xi in the Yixue qimeng.)
Hexagram 49 革, line 2
已日乃革之，征吉，无咎。
The second line, divided, shows its subject making his changes after some time has passed. Action taken will be fortunate. There will be no error.
Hexagram 49 革, line 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.
The two hexagrams
Hexagram 49 革 — judgment
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.
Hexagram 28 大過 — judgment
棟橈，利有攸往，亨。
Tâ Kwo suggests to us a beam that is weak. There will be advantage in moving (under its conditions) in any direction whatever; there will be success.
