Changing lines (counted from the bottom): 2, 3, 4, 5.

What to read

Four changing lines: read the two unchanged lines of the resulting hexagram; the lower one is the main one. (Rule set out by Zhu Xi in the Yixue qimeng.)

Hexagram 1 乾, line 1

潛龍勿用。

In the first (or lowest) line, undivided, (we see its subject as) the dragon lying hid (in the deep). It is not the time for active doing.

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.

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 1 乾 — judgment

元亨。利貞。

Khien (represents) what is great and originating, penetrating, advantageous, correct and firm.

The changing lines of hexagram 27

LineChineseLegge
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.
3拂頤,貞凶,十年勿用,无攸利。The third line, divided, shows one acting contrary to the method of nourishing. However firm he may be, there will be evil. For ten years let him not take any action, (for) it will not be in any way advantageous.
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.
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.
