Zhouyi BenyiLine statement
The hexagram takes things following as its meaning; the lines take following things as their meaning. Nine at the Beginning, as a yang line dwelling below, is the master of Zhèn and that through which the hexagram becomes Following.
Having something to follow, it develops a specific partiality and alters its constancy. Only when it attains correctness is there good fortune. Furthermore, it must go out the gate to interact, not keeping its following private; then it will achieve merit.
Hence its image and prognosis are like this, which also serves as a caution.
