Hexagram 1 乾 changing to hexagram 28 大過
Changing lines (counted from the bottom): 1, 6.
What to read
Two changing lines: read both line texts of the original hexagram; the upper one is the main one. (Rule set out by Zhu Xi in the Yixue qimeng.)
Hexagram 1 乾, line 6
亢龍，有悔。
In the sixth (or topmost) line, undivided, (we see its subject as) the dragon exceeding the proper limits. There will be occasion for repentance.
Hexagram 1 乾, line 1
潛龍勿用。
In the first (or lowest) line, undivided, (we see its subject as) the dragon lying hid (in the deep). It is not the time for active doing.
The two hexagrams
Hexagram 1 乾 — judgment
元亨。利貞。
Khien (represents) what is great and originating, penetrating, advantageous, correct and firm.
Hexagram 28 大過 — judgment
棟橈，利有攸往，亨。
Tâ Kwo suggests to us a beam that is weak. There will be advantage in moving (under its conditions) in any direction whatever; there will be success.
