The image of Jiji is Water above Fire (Kan above Li), water and fire interacting, each in its proper place. In terms of the lines, all six lines of Jiji are in the correct position – yang lines in yang positions, yin lines in yin positions. This makes it the most structurally orderly hexagram in the entire set, symbolizing that things have reached perfection and everything is in neat order. However, the wisdom of the I Ching reminds us: when everything reaches its peak, decline and change quietly begin. The judgment for Jiji says “Success,” but also warns “good fortune at the start, chaos at the end,” meaning that while the beginning is smooth, if you are not careful afterward, disorder may arise. This reminds us that success is not the end – it is the start of a need for vigilant stewardship. Never let a moment of fulfillment lull you into complacency.

The image of Weiji is Fire above Water (Li above Kan), fire above water – the two elements cannot interact, thus the name “Before Completion,” symbolizing that things have not yet been accomplished and are still in a transitional phase. In contrast to Jiji, all six lines of Weiji are in the wrong position, with yin and yang misplaced, appearing chaotic and unsettled. Yet the I Ching does not regard Weiji as a purely ominous sign; instead, it gives it a judgment of “Success.” Why? Because incompleteness means there is still room for change and effort, containing the momentum and hope for progress. The line texts of Weiji repeatedly emphasize “caution” and “perseverance,” encouraging people to remain careful and steadfast when facing unfinished tasks. This positive interpretation of “incompletion” reflects the active, enterprising spirit within Chinese culture.

The I Ching places Jiji, the hexagram of completion, at the 63rd position, and finishes with Weiji, the hexagram of incompletion, as the final hexagram. This arrangement carries deep philosophical meaning. The ancients believed that the movement of heaven and earth does not lead to a static endpoint, but to a cycle of “repetition and endless renewal.” If the book ended with Jiji, it would imply that everything stops. Ending with Weiji signifies that the world is always in a state of change and renewal – an ending is another beginning. This echoes the core idea from the Great Treatise: “Change means production and reproduction.” For modern people, this wisdom reminds us that there is no true finality in life; every stage of completion is the starting point of a new journey. By staying humble and proactive, we can adapt to the way of change.
