易之道 — The Way of Change
〔易 / 不易 / 变易 — the simple · the constant · the changing〕
一阴一阳之谓道，生生之谓易。
The interplay of yin and yang: this is the Way. The endless generation of life: this is Change.
德行恒易以知险，德行恒简以知阻。
Rooted in plainness, it foresees the hazardous; rooted in simplicity, it clears the obstruction.
书不尽言，言不尽意。立象以尽意。仁者见仁，知者见知。
Script cannot exhaust speech, nor speech exhaust meaning; thus images are established to render meaning complete. The benevolent perceive benevolence, while the wise perceive wisdom.
乾，元亨利贞，君子终日乾乾夕惕若；
Qian represents what is great and originating, penetrating, advantageous, correct and firm. The superior man is active and vigilant all the day, and in the evening still careful and apprehensive.
天行健，君子以自强不息，地势坤，君子以厚德载物。
Heaven moves with strength; the noble one accordingly never ceases to strengthen himself. The earth’s disposition is receptive; the noble one accordingly bears all things with generous virtue.
敬以直内，义以方外；广矣大矣，远则不御；迩则静而正；直，方，大，不习无不利。
Reverence straightens the inner life; righteousness squares the outer conduct. Vast and great: reaching afar, nothing resists it; drawing near, it is tranquil and correct. Straight, square, and great—without deliberate practice, nothing fails to prosper.
君子以成德为行，日可见；劳谦君子，劳而不伐，有功而不德；藏器于身，待时而动；动而不括，出而有获；见几而作，不远复。
The noble one makes the perfecting of virtue his conduct, visible day by day. The toiling and modest one labors but does not boast, has merit but claims no virtue; he keeps his tool within, and waits for the moment to move; moving without hindrance, he goes forth and gains; he sees the first stir and acts, and returns before straying far.
穷则变，变则通，通则久。
When exhausted, it changes; changing, it opens through; opening through, it endures.
知至至之，知终终之；知进退存亡而不失其正
Knowing the goal, he reaches it; knowing the end, he brings it to a close; he knows advance and retreat, survival and ruin, and never loses his rectitude.
安不忘危，存不忘亡，治不忘乱；损以远害，益以兴利，小惩而大诫。
In safety, not forgetting danger; in survival, not forgetting ruin; in order, not forgetting disorder. Reducing to avert harm; expanding to foster benefit.; a small punishment for a great warning.
Short & Precise Version in English
Yin and yang in play: the Way. Life begetting life: Change.
Rooted in plainness, it reads the risk; rooted in simplicity, it clears the path.
Script can’t exhaust speech; speech can’t exhaust meaning. Build images to capture the intent. The benevolent see benevolence; the wise see wisdom.
Qian: Primal, penetrating, advantageous, and firm. The leader drives all day, vigilant through the night.
Heaven is strong: the leader endlessly self-corrects. Earth is vast: the leader carries all with virtue.
Reverence centers within; righteousness squares without. Vast and deep: afar, unstoppable; near, still and true. Straight, square, vast—effortless mastery.
The leader enacts virtue daily. The humble worker toils without boasting, holds his tools, and waits for the pivot. Moving unimpeded, he gains; spotting the seed, he acts and never strays.
Exhausted, it shifts; shifting, it opens; opening, it endures.
Knowing the goal, he reaches it; knowing the end, he concludes it. Knowing advance and retreat, survival and ruin, he stays true.
In safety, remember danger; in survival, remember ruin; in order, remember chaos. Cut to protect; add to expand; small corrections prevent great falls.
