Hexagram 34, Dà Zhuàng (Great Power): Line 5
大壮卦六五 · 雷天大壮 · 中文版
六五：丧羊于易，无悔。
The line (Legge)
The fifth SIX, divided, shows one who loses his ram(-like strength) in the ease of his position. (But) there will be no occasion for repentance.
Small Image commentary
'He loses his ram and hardly perceives it:' - he is not in his appropriate place.
象曰：丧羊于易，位不当也。
In plain words
Losing the ram without noticing: no regret. Some read the key word as ease or carelessness, others as a field boundary; some scholars see here the story of the Shang ancestor Wang Hai losing his flocks among the Yi people. The ram stands for strength; the fifth line, yielding in the place of honour, stops forcing things and lightly lets its forcefulness go. The Small Image says its position is not proper.
Applying it to your situation
If you have lost some edge or advantage, this line suggests there is no need for regret: gentleness is strength too. Once you stop forcing things, how else could you act?
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, Dà Zhuàng changes into Hexagram 43 Guài (Breakthrough). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·大壮之夬.
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.
