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 25 无妄, line 5
无妄之疾，勿藥有喜。
The fifth line, undivided, shows one who is free from insincerity, and yet has fallen ill. Let him not use medicine, and he will have occasion for joy (in his recovery).
Hexagram 25 无妄, line 4
可貞，无咎。
The fourth line, undivided, shows (a case) in which, if its subject can remain firm and correct, there will be no error.
The two hexagrams
Hexagram 25 无妄 — judgment
元亨。利貞。其匪正有眚，不利有攸往。
Wû Wang indicates great progress and success, while there will be advantage in being firm and correct. If (its subject and his action) be not correct, he will fall into errors, and it will not be advantageous for him to move in any direction.
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.
