Xiao Guo is the hexagram of overstepping in small things. Thunder rolls above a mountain, and the old readers saw the bird of the figure's lines rising too high above the solid ground — a picture of exceeding the mark, but only in what is small. The judgment draws the line exactly: small things may be done; great things should not be done. There are moments, the text says, when modesty, care, and attention to small matters are the whole of wisdom, and any grand undertaking is out of season.
Read against the working life, the figure is about the danger of small overreaches that accumulate. The first line, the bird meets with misfortune through flying, and the third, if one is not extremely careful somebody may come up from behind, were the commentators' twin warnings. The small excess — the slight overstep, the detail ignored, the step taken without looking — is what brings a person low, and the cure is vigilance over the little things that greatness would brush aside.
For the bonds between people, Xiao Guo was read as the harm done by small neglects. The second line's odd image — she passes by her ancestor and meets her ancestress, he does not reach his prince and meets the official — was the ancients' picture of aiming too high and missing the near. The person who overlooks the small courtesies, the small obligations close at hand, while reaching for grander gestures, is the one the figure warns. It is in the small things, they taught, that a bond is kept or lost.
Within a cycle, this figure marks a phase of retreat to the small, a stretch when the wise course is to lower one's sights and tend the details. The image of thunder over the mountain is the book's picture of a force that must come down to earth again. The counsel is to do the small things well, to be careful rather than bold, and to leave the great undertakings for another season — for now, the flight must keep close to the ground.
