Hexagram 30, Lí (The Clinging Fire): Line 4
离卦九四 · 离为火 · 中文版
九四：突如其来如，焚如，死如，弃如。
The line (Legge)
The fourth NINE, undivided, shows the manner of its subject's coming. How abrupt it is, as with fire, with death, to be rejected (by all)!
Small Image commentary
'How abrupt is the manner of his coming!' - none can bear with him.
象曰：突如其来如，无所容也。
In plain words
Suddenly it comes, like fire, like death, like being cast aside. The Chinese idiom for something coming out of nowhere comes from this line. The fourth line is strong and presses hard on the ruler in the fifth place; its fierce arrival is not accepted. The Small Image says it has nowhere to stay.
Applying it to your situation
If you want to burst into a situation forcefully, this line suggests that too fierce an entrance is often rejected. Is there a gentler way in?
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, Lí changes into Hexagram 22 Bì (Grace). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·离之贲.
The hexagram
Hexagram 30 Lí (The Clinging Fire). The Judgment: Li indicates that, (in regard to what it denotes), it will be advantageous to be firm and correct, and that thus there will be free course and success. Let (its subject) also nourish (a docility like that of) the cow, and there will be good fortune.
