Hexagram 64 未濟 changing to hexagram 18 蠱
Changing lines (counted from the bottom): 3, 4.
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 64 未濟, line 4
貞吉，悔亡，震用伐鬼方，三年有賞于大國。
The fourth line, 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.
Hexagram 64 未濟, line 3
未濟，征凶，利涉大川。
The third line, divided, shows its subject, with (the state of things) not yet remedied, advancing on; which will lead to evil. But there will be advantage in (trying to) cross the great stream.
The two hexagrams
Hexagram 64 未濟 — judgment
亨。小狐汔濟，濡其尾，无攸利。
Wei Zî intimates progress and success (in the circumstances which it implies). (We see) a young fox that has nearly crossed (the stream), when its tail gets immersed. There will be no advantage in any way.
Hexagram 18 蠱 — judgment
元亨。利涉大川。先甲三日，後甲三日。
Kû indicates great progress and success (to him who deals properly with the condition represented by it). There will be advantage in (efforts like that of) crossing the great stream. (He should weigh well, however, the events of) three days before the turning point, and those (to be done) three days after it.
