Primary & Relating Hexagrams

The primary hexagram preserves the cast structure; the relating hexagram shows the structure after moving lines flip. Traditional readings use them to examine the present arrangement and its changed associations. Construction alone does not provide a dated sequence of events. Najia also traces the specific changed line positions.

The primary hexagram records six lines bottom to top. The relating hexagram changes each 6 from yin to yang and each 9 from yang to yin, leaving 7 and 8 unchanged. After the flips, identify the new lower and upper trigrams and hexagram name.

Flipping only Qian’s bottom line produces Hexagram 44, Gou; flipping all six produces Kun. Without moving lines the structure remains the same, without a distinct relating hexagram. Najia also compares the moving and transformed branches and their relationships, including generation or control back toward the original line.

Continue Qian changing at the bottom to Gou: the original branch is Zi water and the changed branch Chou earth. Using Qian’s metal reference, Zi is Offspring and Chou Parents; earth controls water, giving transformed control back toward the original line. The operative explanation is a relationship between roles, not merely two hexagram names.

Also distinguish the relating hexagram’s own palace classification from the primary-palace reference used when comparing changing relationships. Keep the reference consistent within that comparison.
