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 18 蠱, line 4
裕父之蠱，往見吝。
The fourth line, divided, shows (a son) viewing indulgently the troubles caused by his father. If he go forward, he will find cause to regret it.
Hexagram 18 蠱, line 3
幹父之蠱，小有悔，无大咎。
The third line, undivided, shows (a son) dealing with the troubles caused by his father. There may be some small occasion for repentance, but there will not be any great error.
The two hexagrams
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.
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.
