既濟

Ji Ji is not success itself. It is the condition immediately after completion — when every line occupies its proper position, and the completed order can begin to deteriorate if it is treated as finished and no longer renewed. Water (Kan) above Fire (Li) forms a working arrangement: water heated from below, fire contained from above. Every firm line sits in a firm place and every yielding line in a yielding one. The structure is entirely correct, and for that reason the danger lies not in having achieved order but in assuming achieved order sustains itself. The Tuan puts the condition precisely: 終止則亂 — it is the stopping at completion, not the completion, that produces disorder. The judgment reads 亨小。利貞。初吉。終亂 — "constancy furthers; good fortune at the beginning, disorder at the end." The Tuan glosses 亨小 as 小者亨也: even the small has been brought through. That also names the work that remains. Once the principal task is accomplished, stability depends on attention to small things — the details, minor deviations and neglected maintenance by which disorder first returns. 初九 gives the posture: 曳其輪，濡其尾，无咎 — "dragging back the wheel, wetting the tail; no blame." The crossing has only just been made and the tail is not yet clear of the water. The operative act is 曳其輪: restraining further movement exactly when success invites haste. The line is blameless because it does not mistake arrival for permission to rush. 六二 loses her carriage-screen and is told 勿逐，七日得 — "do not pursue it; in seven days it returns." The seven-day measure echoes 復 and 震: what belongs to a cycle comes back through time rather than through anxious pursuit. Even inside a completed order, not everything should be recovered by immediate intervention. 九五 holds the hexagram's finest measure: 東鄰殺牛，不如西鄰之禴祭，實受其福 — "the eastern neighbour slaughters an ox; it does not equal the western neighbour's modest seasonal offering, which truly receives the blessing." At the summit of accomplishment, abundance cannot compensate for being out of time or lacking sincerity. The great sacrifice is inferior not because it is large but because the smaller one is better aligned with the moment and with the virtue of whoever offers it. Read that beside hexagram 41's 二簋可用享 and hexagram 45's 用大牲. The right scale of an offering depends on the situation. Economy is not inherently better than abundance, nor abundance than economy. What matters is proportion — the right act, in the right measure, at the right time. The Image gives the discipline of completion: 水在火上，既濟；君子以思患而豫防之 — "the superior person considers misfortune and takes precautions against it in advance." Completion is not merely a time for celebration. It is the moment to ask where the achieved order is likeliest to fail, and to strengthen it before the failure shows. 上六 shows what neglecting that costs: 濡其首，厲 — "the head is immersed; danger." At the first line only the tail was wet; at the last the whole head has gone under. The movement was carried too far and the restraint is gone. Ji Ji's purpose is therefore vigilance within achievement. Completion is neither a permanent destination nor an inevitable slide into chaos. It is a momentary equilibrium; once maintenance stops, it begins to turn toward disorder. What has been achieved may demand as much attention to keep as it took effort to make.
