Zhouyi BenyiLine statement
Yin, yielding, and a petty person, having strong support above and catching the time when the master manages affairs, cannot bear its enthusiasm and sings its own praises in sound; this is the way to misfortune. Hence the prognosis is such.
The hexagram gets its name primarily from harmony and joy; however, the hexagram judgment carries the meaning of collective joy for the multitude, while the line judgments—except for Nine in the Fourth Place, which agrees with the hexagram—all represent private self-indulgence.
This is why good fortune and misfortune differ.
