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 4
或躍在淵，无咎。
In the fourth line, undivided, (we see its subject as the dragon looking) as if he were leaping up, but still in the deep. There will be no mistake.
The two hexagrams
Hexagram 1 乾 — judgment
元亨。利貞。
Khien (represents) what is great and originating, penetrating, advantageous, correct and firm.
Hexagram 5 需 — judgment
有孚，光亨。貞吉，利涉大川。
Hsü intimates that, with the sincerity which is declared in it, there will be brilliant success. With firmness there will be good fortune; and it will be advantageous to cross the great stream.
