CHAPTER 01
Only old yin and old yang are changing lines.
A cast does not merely produce yin or yang. It produces one of four line values: 6, 7, 8, or 9. Young lines are stable; old lines are changing.
6 = old yin = changing yin
7 = young yang = stable yang
8 = young yin = stable yin
9 = old yang = changing yang
CHAPTER 02
A changing line flips to create the resulting hexagram.
Old yin becomes yang; old yang becomes yin. Flip every changing line in the primary hexagram and you get the resulting hexagram. If there are no changing lines, the primary hexagram is the whole structure.
Primary hexagram
The six-line structure directly produced by the cast.
Resulting hexagram
The structure after every changing line has flipped.
CHAPTER 03
A changing line is not an automatic answer.
It is the location of structural change. Hexagram Cast separates primary hexagram, moving-line text, resulting hexagram, nuclear hexagram, and trace so that the reading does not collapse into a single mystical verdict.
