火水未济
Hexagram 64 is the final hexagram of the I Ching — and it describes not completion but the threshold before completion. Wèi Jì is the moment of maximum potential, when everything is in motion but nothing is yet settled. The young fox has almost crossed the river; one more careful step and the crossing is complete. But carelessness at this final moment can undo everything.
未济：亨，小狐汔济，濡其尾，无攸利。
事未竟成、尚可有为：亨通；但如小狐渡河将近成功却湿了尾巴，功亏一篑则无所利——须坚持到底。
Interpretive translationBefore Completion. Success. But if the little fox, after nearly completing the crossing, gets his tail in the water, there is nothing that would further.

Structure
Wèi Jì is formed by Fire (Li ☲) above Water (Kan ☵). Fire rises; water descends — they move away from each other, and their interaction is incomplete. Every line of the hexagram is in the wrong position: yang lines occupy yin positions and yin lines occupy yang positions. This structural disorder is the mirror image of Jì Jì's perfect order — the same elements, the same lines, but none yet in their proper place. The potential for order is present; the realization of that order is the work still to be done.
Judgment and Image
The Judgment states: Before Completion. Success. But if the little fox, after nearly completing the crossing, gets his tail in the water, there is nothing that would further. The Image shows fire over water — the superior person is careful to discriminate between things, so that each finds its place. The little fox image is vivid: the crossing is almost complete, but a moment of carelessness — the tail dipping into the water — ruins everything. Discrimination and care at the final moment are everything.
Core meaning
The central teaching of Wèi Jì is that the threshold state is both the most promising and the most dangerous moment. Everything is in motion, the goal is in sight, and the potential for completion is at its maximum. But precisely because everything is still in flux, a single misstep can undo the entire effort. The care and discrimination required at this moment are greater than at any earlier stage.
The I Ching ends with this hexagram rather than with Jì Jì (After Completion) for a profound reason: the cycle of existence never truly ends. Every completion is followed by a new beginning, every order by a new disorder, every crossing by a new river. Wèi Jì, the hexagram of before completion, is the more honest description of the human condition — always in process, always approaching but never finally arriving.
In Liuyao readings, Wèi Jì often appears when the querent is close to achieving something important but has not yet crossed the threshold. The hexagram affirms the proximity of success while counseling extreme care and discrimination in the final steps. This is not the time for relaxation or celebration but for the most careful, attentive action of the entire process.
The image of discriminating between things — ensuring that each finds its proper place — points to the specific work of the threshold moment. The elements of the new order are all present; the task is to arrange them correctly. This requires clear seeing, careful judgment, and the patience to place each thing where it truly belongs rather than where it is convenient.
In divination
When Wèi Jì appears in a reading, it signals that the goal is close but not yet achieved, and that careful discrimination is essential. For career questions, it may indicate that a project or transition is nearly complete and requires careful attention to the final details. For personal matters, it counsels patience and care at the threshold of a significant change.
Wèi Jì is favorable for careful final steps, discrimination, patient attention to detail, and situations where the goal is in sight. It is unfavorable for premature celebration, carelessness at the final stage, or rushing the last steps of a long process.
