Enthusiasm

鳴豫，凶。

Proclaiming one’s delight. Misfortune.

The first line boasts of its delight because it relies on strong support above. The warning concerns that overconfidence. Changing Line 1 to firm turns lower earth to thunder and produces Hexagram 51.

介于石，不終日，貞吉。

Firm as stone, not waiting to the end of the day. Constancy is favorable.

Stone-like firmness and action before day's end are assigned to the centered second line. When this yielding line becomes firm, lower earth turns to water and the result is Hexagram 40.

盱豫悔，遲有悔。

Looking upward for pleasure brings regret. Delay also brings regret.

Line 3 looks up to the sole firm line for satisfaction instead of standing securely in its own position. Regret calls for a change in that dependence. Changing Line 3 to firm turns lower earth to mountain and produces Hexagram 62.

由豫，大有得。勿疑，朋盍簪。

The source of enthusiasm: much is gained. Do not doubt. Friends gather around.

Line 4 is the source of shared enthusiasm and the figure’s only firm place. Its confidence allows the other lines to gather around it. Changing this line to yielding produces the six broken lines of Hexagram 2.

貞疾，恆不死。

A lasting illness, yet one does not die.

Persistent illness occupies Line 5, the yielding center directly above the hexagram's firm source. Turning it firm changes upper thunder to lake and produces Hexagram 45.

冥豫成，有渝无咎。

Lost in pleasure. Even after it has taken hold, a change of course brings no fault.

The top line has become absorbed in pleasure, but the text leaves room to correct that settled habit. Changing Line 6 to firm turns upper thunder into fire and produces Hexagram 35.
