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 16 豫, line 2

介于石,不終日,貞吉。

The second line, divided, shows one who is firm as a rock. (He sees a thing) without waiting till it has come to pass; with his firm correctness there will be good fortune.

Hexagram 16 豫, line 3

盱豫,悔。遲有悔。

The third line, divided, shows one looking up (for favours), while he indulges the feeling of pleasure and satisfaction. If he would understand!—If he be late in doing so, there will indeed be occasion for repentance.

The two hexagrams

Hexagram 42 益 — judgment

利有攸往。利涉大川。

Yî indicates that (in the state which it denotes) there will be advantage in every movement which shall be undertaken, that it will be advantageous (even) to cross the great stream.

Hexagram 16 豫 — judgment

利建侯行師。

Yü indicates that, (in the state which it implies), feudal princes may be set up, and the hosts put in motion, with advantage.

The changing lines of hexagram 42

LineChineseLegge
1利用為大作,元吉,无咎。The first line, undivided, shows that it will be advantageous for its subject in his position to make a great movement. If it be greatly fortunate, no blame will be imputed to him.
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.
5有孚惠心,勿問元吉。有孚惠我德。The fifth line, undivided, shows its subject with sincere heart seeking to benefit (all below). There need be no question about it; the result will be great good fortune. (All below) will with sincere heart acknowledge his goodness.
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.
