Hexagram 34, Dà Zhuàng (Great Power): Line 3
大壮卦九三 · 雷天大壮 · 中文版
九三：小人用壮，君子用罔，贞厉。羝羊触藩，羸其角。
The line (Legge)
The third NINE, undivided, shows, in the case of a small man, one using all his strength; and in the case of a superior man, one whose rule is not to do so. Even with firm correctness the position would be perilous. (The exercise of strength in it might be compared to the case of) a ram butting against a fence, and getting his horns entangled.
Small Image commentary
'The small man uses all his strength; in the case of the superior man it is his rule not to do so.'
象曰：小人用壮，君子罔也。
In plain words
The petty person uses strength; the noble person does not; holding on is dangerous. A ram butts a fence and gets its horns caught. The third line has gone past the middle in strength and loves a fight. The Small Image says the petty person relies on strength, and the noble person does not do this.
Applying it to your situation
If you want to solve a problem by brute force, this line suggests butting your head against it will only get you stuck. Is there a way that does not need force?
Position
A solid (yang) line in the third place, which is a yang (odd) place, so it is 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, Dà Zhuàng changes into Hexagram 54 Guī Mèi (The Marrying Maiden). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·大壮之归妹.
The hexagram
Hexagram 34 Dà Zhuàng (Great Power). The Judgment: Da Zhuang indicates that (under the conditions which it symbolises) it will be advantageous to be firm and correct.
