The changing lines of hexagram 42
| Line | Chinese | Legge |
|---|---|---|
| 3 | 益之用凶事，无咎。有孚中行，告公用圭。 | The third line, divided, shows increase given to its subject by means of what is evil, so that he shall (be led to good), and be without blame. Let him be sincere and pursue the path of the Mean, (so shall he secure the recognition of the ruler, like) an officer who announces himself to his prince by the symbol of his rank. |
| 4 | 中行，告公從。利用為依遷國。 | The fourth line, divided, shows its subject pursuing the due course. His advice to his prince is followed. He can with advantage be relied on in such a movement as that of removing the capital. |
| 6 | 莫益之，或擊之，立心勿恆，凶。 | In the sixth line, undivided, we see one to whose increase none will contribute, while many will seek to assail him. He observes no regular rule in the ordering of his heart. There will be evil. |
