Hexagram 27 頤 changing to hexagram 4 蒙
Changing lines (counted from the bottom): 1, 2.
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 2
顛頤，拂經，于丘頤，征凶。
The second line, divided, shows one looking downwards for nourishment, which is contrary to what is proper; or seeking it from the height (above), advance towards which will lead to evil.
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 4 蒙 — judgment
亨。匪我求童蒙，童蒙求我。初筮告，再三瀆，瀆則不告。利貞。
Măng (indicates that in the case which it presupposes) there will be progress and success. I do not (go and) seek the youthful and inexperienced, but he comes and seeks me. When he shows (the sincerity that marks) the first recourse to divination, I instruct him. If he apply a second and third time, that is troublesome; and I do not instruct the troublesome. There will be advantage in being firm and correct.
