Hexagram 25 无妄 changing to hexagram 49 革
Changing lines (counted from the bottom): 3, 6.
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 25 无妄, line 6
无妄，行有眚，无攸利。
The topmost line, undivided, shows its subject free from insincerity, yet sure to fall into error, if he take action. (His action) will not be advantageous in any way.
Hexagram 25 无妄, line 3
无妄之災，或繫之牛，行人之得，邑人之災。
The third line, divided, shows calamity happening to one who is free from insincerity;—as in the case of an ox that has been tied up. A passer by finds it (and carries it off), while the people in the neighbourhood have the calamity (of being accused and apprehended).
The two hexagrams
Hexagram 25 无妄 — judgment
元亨。利貞。其匪正有眚，不利有攸往。
Wû Wang indicates great progress and success, while there will be advantage in being firm and correct. If (its subject and his action) be not correct, he will fall into errors, and it will not be advantageous for him to move in any direction.
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.
