Hexagram 27 頤 changing to hexagram 20 觀
Changing lines (counted from the bottom): 1, 5.
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 27 頤, line 5
拂經，居貞吉，不可涉大川。
The fifth line, divided, shows one acting contrary to what is regular and proper; but if he abide in firmness, there will be good fortune. He should not, (however, try to) cross the great stream.
Hexagram 27 頤, line 1
舍爾靈龜，觀我朵頤，凶。
The first line, undivided, (seems to be thus addressed), 'You leave your efficacious tortoise, and look at me till your lower jaw hangs down.' There will be evil.
The two hexagrams
Hexagram 27 頤 — judgment
貞吉。觀頤，自求口實。
Î indicates that with firm correctness there will be good fortune (in what is denoted by it). We must look at what we are seeking to nourish, and by the exercise of our thoughts seek for the proper aliment.
Hexagram 20 觀 — judgment
盥而不薦，有孚顒若。
Kwân shows (how he whom it represents should be like) the worshipper who has washed his hands, but not (yet) presented his offerings;—with sincerity and an appearance of dignity (commanding reverent regard).
