Hexagram 42, Yì (Increase): Line 3
益卦六三 · 风雷益 · 中文版
六三：益之用凶事，无咎。有孚中行，告公用圭。
The line (Legge)
The third SIX, 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.
Small Image commentary
'Increase is given by means of what is evil and difficult:' - as he has in himself (the qualities called forth).
象曰：益用凶事，固有之也。
In plain words
Increased through unfortunate events: no fault. With sincerity, walking the middle way, one reports to the duke with a jade tablet. The jade tablet was a token of good faith. The third line is neither central nor correct and can only gain in a crisis, but it must stay sincere and balanced. The Small Image says this is what it rightly has.
Applying it to your situation
If you have been helped through a difficult time, this line suggests explaining the situation honestly. To whom do you owe a frank account?
Position
A broken (yin) line in the third place, which is a yang (odd) place, so it is not in its proper place. Its partner is line 6; 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 37 Jiā Rén (The Family). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·益之家人.
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.
