Hexagram 26, Dà Chù (Great Taming): Line 5
大畜卦六五 · 山天大畜 · 中文版
六五：豮豕之牙，吉。
The line (Legge)
The fifth six, divided, shows the teeth of a castrated hog. There will be good fortune.
Small Image commentary
'The good fortune indicated by the fifth six, (divided),' shows that there is occasion for congratulation.
象曰：六五之吉，有庆也。
In plain words
The tusks of a gelded boar: good fortune. Once gelded, a boar grows docile, and its tusks, though still there, do no harm. The fifth line holds back the second not by force but by removing its aggression at the root. The Small Image says there is cause for celebration.
Applying it to your situation
If you need to restrain a strong force, this line suggests guiding it at the source rather than simply suppressing it. Where is the root of the problem?
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 Chù changes into Hexagram 9 Xiǎo Chù (Small Taming). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·大畜之小畜.
The hexagram
Hexagram 26 Dà Chù (Great Taming). The Judgment: Under the conditions of Da Xu it will be advantageous to be firm and correct. (If its subject do not seek to) enjoy his revenues in his own family (without taking service at court), there will be good fortune. It will be advantageous for him to cross the great stream.
