Hexagram 51, Zhèn (The Arousing Thunder): Line 5
震卦六五 · 震为雷 · 中文版
六五：震往来厉，亿无丧，有事。
The line (Legge)
The fifth SIX, divided, shows its subject going and coming amidst the startling movements (of the time), and always in peril; but perhaps he will not incur loss, and find business (which he can accomplish).
Small Image commentary
'He goes and comes amid the startling movements, and (always) in peril:' - full of risk are his doings. 'What he has to do has to be done in his central position:' - far will he be from incurring any loss.
象曰：震往来厉，危行也。其事在中，大无丧也。
In plain words
Thunder comes and goes with danger; one expects no loss, and there is work to be done. The fifth line is yielding in the place of honour amid the shaking, but it is central and can hold on to what must be done. The Small Image says moving in danger is acting amid peril, and keeping its work at the centre means there is no great loss.
Applying it to your situation
If you are in the middle of ongoing upheaval, this line suggests holding on to the core task so that nothing essential is lost. What one thing should you hold on to now?
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; both are yin, so they do not respond.
If this line moves
With this line moving alone, Zhèn changes into Hexagram 17 Suí (Following). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·震之随.
A recorded case from Takashima
Zhen to Sui: an heir long held down: A friend asked about the fortunes of a family's heir and received the fifth line of Zhen, "shock comes and goes, danger; nothing is lost, there is work to do". From the figure Takashima inferred that the household had long been run by its mistress and the heir kept down; now his strength had grown and he could step up, and if he stayed careful and self-examining he would keep the family line. They followed the reading.
The hexagram
Hexagram 51 Zhèn (The Arousing Thunder). The Judgment: Zhen gives the intimation of ease and development. When (the time of) movement (which it indicates) comes, (the subject of the hexagram) will be found looking out with apprehension, and yet smiling and talking cheerfully. When the movement (like a crash of thunder) terrifies all within a hundred Li, he will be (like the sincere worshipper) who is not (startled into) letting go his ladle and (cup of) sacrificial spirits.
