a yellow circle, indicating this line as the governing ruler of the hexagram Nine in the fifth place means:

The abyss is not filled to overflowing,
It is filled only to the rim.

Danger comes because one is too ambitious. In order to flow out of a ravine, water does not rise higher than the lowest point of the rim. So likewise a man when in danger has only to proceed along the line of least resistance; thus he reaches the goal. Great labors cannot be accomplished in such times; it is enough to get out of the danger.
