Línea por línea
Línea 1：壮于趾，征凶，有孚。 Strength in the toes — campaigning is dangerous; have sincerity. Power at the base but not yet mature; rash action is risky.
Línea 2：贞吉。 Staying upright brings good fortune. Power directed correctly.
Línea 3：小人用壮，君子用罔，贞厉。羝羊触藩，羸其角。 The small use brute force; the noble do not. A ram butting the hedge gets its horns stuck. Wisdom over force.
Línea 4：贞吉，悔亡。藩决不羸，壮于大舆之輹。 Staying upright — good fortune, regret vanishes. The hedge is breached; strong as a great carriage axle. Breakthrough achieved.
Línea 5：丧羊于易，无悔。 Losing sheep at the field's edge — no regret. Small losses do not harm the core.
Línea 6：羝羊触藩，不能退，不能遂，无攸利。艰则吉。 The ram butts the hedge — can neither retreat nor advance; no benefit. Through hardship comes good fortune. Stuck between extremes, perseverance resolves it.
