Hexagram 11, Tài (Peace): Line 5
泰卦六五 · 地天泰 · 中文版
六五：帝乙归妹，以祉元吉。
The line (Legge)
The fifth six, divided, reminds us of (king) Di-yi's (rule about the) marriage of his younger sister. By such a course there is happiness and there will be great good fortune.
Small Image commentary
'By such a course there is happiness, and there will be great good fortune:' - (the subject of the line) employs the virtue proper to his central position to carry his wishes into effect.
象曰：以祉元吉，中以行愿也。
In plain words
King Di Yi gives his younger sister in marriage; this brings blessings and supreme good fortune. Di Yi was a king of the Shang. The fifth line is yielding in the place of honour and corresponds to the second below: the honoured one yields to the humble, and so blessings come. The Small Image says it keeps to the middle to fulfil its wishes.
Applying it to your situation
If you are in a higher position, this line suggests setting status aside to make a partnership work. Is there something that needs you to lower yourself first?
Position
A broken (yin) line in the fifth place, which is a yang (odd) place, so it is not in its proper place. It holds the centre of the upper trigram. Its partner is line 2; one is yin and the other yang, so they respond to each other.
If this line moves
With this line moving alone, Tài changes into Hexagram 5 Xū (Waiting). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·泰之需.
The hexagram
Hexagram 11 Tài (Peace). The Judgment: In Tai (we see) the little gone and the great come. (It indicates that) there will be good fortune, with progress and success.
