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 4
顛頤吉，虎視眈眈，其欲逐逐，无咎。
The fourth line, divided, shows one looking downwards for (the power to) nourish. There will be good fortune. Looking with a tiger's downward unwavering glare, and with his desire that impels him to spring after spring, he will fall into no error.
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 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.
