Original, resulting, and changing lines
Rule
- Original hexagram (ben gua): the hexagram from six casts—present state and starting point.
- Moving line: positions of old yang / old yin—the triggers of change. See Moving line.
- Resulting hexagram (zhi gua): after every moving line flips yin/yang—the trend; no movers → no resulting hexagram (still chart).
Consulting the source text
- Original hexagram statement: if Qian, see Zhou Yi · Qian.
- Moving-line statements: match each mover under that hexagram.
- Resulting hexagram statement: if it becomes Kun, see Zhou Yi · Kun.
- End-state open/blocked imagery may be compared with Ji Ji and Wei Ji, but still return to the useful spirit on the chart.
Look up names via the Sixty-four hexagrams index.
Multiple movers and still charts
- Several lines moving: synthesize by the school’s multi-mover rules; match each mover’s text in turn and avoid over-dissecting.
- Still chart: emphasize original structure, shi/ying, and useful spirit with day/month (if used); only the original chapter is needed.
Boundaries
- Original / resulting / change is the operational structure; scripture is the text layer. Both should map to concrete hexagram or line statements—do not name a hexagram without a textual anchor.
