Hexagram 8 比 changing to hexagram 18 蠱
Changing lines (counted from the bottom): 2, 3, 5, 6.
What to read
Four changing lines: read the two unchanged lines of the resulting hexagram; the lower one is the main one. (Rule set out by Zhu Xi in the Yixue qimeng.)
Hexagram 18 蠱, line 1
幹父之蠱，有子考，无咎，厲終吉。
The first line, divided, shows (a son) dealing with the troubles caused by his father. If he be an (able) son, the father will escape the blame of having erred. The position is perilous, but there will be good fortune in the end.
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.
The two hexagrams
Hexagram 8 比 — judgment
吉。原筮元永貞，无咎。不寧方來，後夫凶。
Pî indicates that (under the conditions which it supposes) there is good fortune. But let (the principal party intended in it) re-examine himself, (as if) by divination, whether his virtue be great, unintermitting, and firm. If it be so, there will be no error. Those who have not rest will then come to him; and with those who are (too) late in coming it will be ill.
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.
The changing lines of hexagram 8
| Line | Chinese | Legge |
|---|---|---|
| 2 | 比之自內，貞吉。 | In the second line, divided, we see the movement towards union and attachment proceeding from the inward (mind). With firm correctness there will be good fortune. |
| 3 | 比之匪人。 | In the third line, divided, we see its subject seeking for union with such as ought not to be associated with. |
| 5 | 顯比。王用三敺，失前禽，邑人不誡，吉。 | The fifth line, undivided, affords the most illustrious instance of seeking union and attachment. (We seem to see in it) the king urging his pursuit of the game (only) in three directions, and allowing the escape of all the animals before him, while the people of his towns do not warn one another (to prevent it). There will be good fortune. |
| 6 | 比之无首，凶。 | In the topmost line, divided, we see one seeking union and attachment without having taken the first step (to such an end). There will be evil. |
