Hexagram 38, Kuí (Opposition): Line 4
睽卦九四 · 火泽睽 · 中文版
九四：睽孤，遇元夫，交孚，厉无咎。
The line (Legge)
The fourth NINE, undivided, shows its subject solitary amidst the (prevailing) disunion. (But) he meets with the good man (represented by the first line), and they blend their sincere desires together. The position is one of peril, but there will be no mistake.
Small Image commentary
'They blend their sincere desires together, and there will be no error:' - their (common) aim is carried into effect.
象曰：交孚无咎，志行也。
In plain words
Isolated by opposition, one meets a good man; they trust each other: danger, but no fault. The good man is the first line. The fourth line sits between two yin lines, alone and unsupported, and joins with the first, which shares its nature. The Small Image says trusting each other brings no fault, and its aims are carried out.
Applying it to your situation
If you feel isolated, this line suggests that one sincere companion is enough to change things. Who could you be fully honest with?
Position
A solid (yang) line in the fourth place, which is a yin (even) place, so it is not in its proper place. Its partner is line 1; both are yang, so they do not respond.
If this line moves
With this line moving alone, Kuí changes into Hexagram 41 Sǔn (Decrease). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·睽之损.
The hexagram
Hexagram 38 Kuí (Opposition). The Judgment: Kui indicates that, (notwithstanding the condition of things which it denotes), in small matters there will (still) be good success.
