Shihe :: Biting
Offering :: Fitting to use punitive measures
The hexagram pictures an open mouth with teeth bared about to bite through an obstruction and/or the lips pursed to sip a libation. Shike represents going forward forcefully and impulsively. It is biting down hard, in an effort to bite through an obstacle. It also means meting out harsh punishment (sipping poison) when it is appropriate. Shihe describes the various results that come from the use of force.
There is a great chance of miscalculation here. One feels obstructed and decides to use force (punishment), but breakthroughs (harsh justice) may also create adversity (backlash). Generally inauspicious, but some cases only mild injuries occur.
A Zhou leader was both a warrior and a sage, not a brute. Good leaders know that it is their own miscalculations and poor management that lead to the need for a strong use of force (war). When we resort to harsh punishments we must do so cautiously-even humbly.
However, sometimes, deliberate confrontation and strong action can be useful in the reunification of allies. What is obstructing unity and justice must be dealt with deliberately. A correct use of force must be cautiously restrained and then abandoned before it degenerates into brutality. Uncontrolled impulses lead to injustice and loss of unity. If you are addicted to impulse and brutality you will never become a true leader.
