Hexagram 42, Yì (Increase): Line 1
益卦初九 · 风雷益 · 中文版
初九：利用为大作，元吉，无咎。
The line (Legge)
The first NINE, 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.
Small Image commentary
'If the movement be greatly fortunate, no blame will be imputed to him:' - though it is not for one in so low a position to have to do with great affairs.
象曰：元吉无咎，下不厚事也。
In plain words
It is favourable to undertake great works: supreme good fortune, no fault. The first line is strong and low and, increased from above, can do great things; but because it is lowly, only great good fortune will keep it free of fault. The Small Image says those below should not normally take on heavy affairs.
Applying it to your situation
If you have been given support and a free hand, this line suggests delivering a good result is what honours that trust. How will you make good on this chance?
Position
A solid (yang) line in the first place, which is a yang (odd) place, so it is in its proper place. Its partner is line 4; 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 20 Guān (Contemplation). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·益之观.
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.
