Hexagram 8 比 changing to hexagram 21 噬嗑
Changing lines (counted from the bottom): 1, 4, 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 21 噬嗑, line 2
噬膚滅鼻，无咎。
The second line, divided, shows one biting through the soft flesh, and (going on to) bite off the nose. There will be no error.
Hexagram 21 噬嗑, line 3
噬昔肉，遇毒；小吝，无咎。
The third line, divided, shows one gnawing dried flesh, and meeting with what is disagreeable. There will be occasion for some small regret, but no (great) error.
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 21 噬嗑 — judgment
亨。利用獄。
Shih Ho indicates successful progress (in the condition of things which it supposes). It will be advantageous to use legal constraints.
The changing lines of hexagram 8
| Line | Chinese | Legge |
|---|---|---|
| 1 | 有孚，比之，无咎。有孚盈缶，終來有它，吉。 | The first line, divided, shows its subject seeking by his sincerity to win the attachment of his object. There will be no error. Let (the breast) be full of sincerity as an earthenware vessel is of its contents, and it will in the end bring other advantages. |
| 4 | 外比之，貞吉。 | In the fourth line, divided, we see its subject seeking for union with the one beyond himself. With firm correctness there will be good fortune. |
| 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. |
