Hexagram 4 蒙 changing to hexagram 18 蠱
Changing line (counted from the bottom): 3.
What to read
One changing line: read the text of that line in the original hexagram. (Rule set out by Zhu Xi in the Yixue qimeng.)
Hexagram 4 蒙, line 3
勿用取女，見金夫，不有躬，无攸利。
The third line, divided, (seems to say) that one should not marry a woman whose emblem it might be, for that, when she sees a man of wealth, she will not keep her person from him, and in no wise will advantage come from her.
The two hexagrams
Hexagram 4 蒙 — judgment
亨。匪我求童蒙，童蒙求我。初筮告，再三瀆，瀆則不告。利貞。
Măng (indicates that in the case which it presupposes) there will be progress and success. I do not (go and) seek the youthful and inexperienced, but he comes and seeks me. When he shows (the sincerity that marks) the first recourse to divination, I instruct him. If he apply a second and third time, that is troublesome; and I do not instruct the troublesome. There will be advantage in being firm and correct.
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.
