A carriage that cannot move is the image at the second position, its strap or axle fitting taken away so that the vehicle stands where it is. Legge's translation gives the picture without attaching either good fortune or misfortune to it, and that silence is the point: the halt is neither a punishment nor a reward, but simply a fact about the state of things.
Commentary reads this line as the willing counterpart of the one below it. The opening position was warned to stop and might have pressed on regardless; here the means of advancing have been set aside, and the tradition treats the setting aside as deliberate rather than inflicted. A strong stroke stands in an even place, incorrect by the classical rule and central to the lower trigram Qian, and that centrality is what turns what could have been frustration into composure.
Within the hexagram this is where restraint stops being resisted. Great Taming accumulates by holding force in reserve, and a carriage stripped of its strap is force intact and unspent rather than force defeated. Nothing has been damaged, nothing has been surrendered, and everything remains available for the moment when the fittings are put back on. That distinction, between a halt that preserves and a halt that defeats, is what this position contributes to the hexagram as a whole.
