As a changing line, nine in the fifth place describes leadership that succeeds by sharing rather than by hoarding, drawing neighboring lines into a common cause instead of directing them from a distance. Sitting central and correctly placed in the ruling position of Xun, the upper trigram, it is the line from which the hexagram's whole gentle restraint is exercised, and a reading here concerns exactly that kind of generous, cooperative authority.
Flipping this line changes the upper trigram from Xun to Gen, Mountain, giving Gen over Qian, the hexagram called Great Taming. Small Taming's picture of a slight, gentle force holding back a great one is replaced by its own larger counterpart, a hexagram of accumulated strength and virtue on a far greater scale, still restrained but now by something as solid and enduring as a mountain rather than by wind alone. The movement is from a small, personally shared restraint toward a great, structurally accumulated one, the same theme carried to a far larger scale.
In Small Taming's own arc, the fifth line is where the hexagram's gentle authority is actually seated, the ruling point the fourth line's sincerity ultimately serves. A reading landing here suggests that present success by sharing resources and drawing others in is not the limit of the pattern, but an early, smaller version of a far greater accumulation still to come.
