Hexagram 42, Yì (Increase): Line 4
益卦六四 · 风雷益 · 中文版
六四：中行，告公从。利用为依迁国。
The line (Legge)
The fourth SIX, 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.
Small Image commentary
'His advice to his prince is followed:' - his (only) object in it being the increase (of the general good).
象曰：告公从，以益志也。
In plain words
Walking the middle way, one reports to the duke and is heeded; it is favourable to be relied on in moving the capital. The fourth line is at the bottom of the upper trigram and carries out the work of decreasing above to increase below; it is fair and trusted. In ancient times the capital was moved for the people's good. The Small Image says being heeded comes from aiming to benefit the people.
Applying it to your situation
If you want to drive a big change, this line suggests you will be supported if its starting point is the good of everyone. Who does this change benefit?
Position
A broken (yin) line in the fourth place, which is a yin (even) place, so it is in its proper place. Its partner is line 1; one is yin and the other yang, so they respond to each other.
If this line moves
With this line moving alone, Yì changes into Hexagram 25 Wú Wàng (Innocence). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·益之无妄.
The hexagram
Hexagram 42 Yì (Increase). The Judgment: Yi 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.
