Yilin Verse
張弓廓弩，經涉山道；雖有伏虎，誰敢害諸。
Drawing the bow, spanning the crossbow, traversing the mountain road; though a tiger lies in ambush, who dares harm him?
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder breaks from the earth as bows are strung and crossbows cocked. The armed party traverses mountain roads where tigers lurk in ambush — yet who dares threaten them? The verse radiates confidence: a well-armed force moving through dangerous terrain without fear. The weapons are drawn not in panic but in disciplined readiness. From Enthusiasm to Biting Through, the transformation channels this martial energy into judicial force. Biting Through's image is lightning and thunder together — the ancient kings used this to clarify punishments and enforce law. The armed traveler's boldness becomes the state's righteous authority: danger exists, but preparedness and legitimate power render it harmless.
