Duration

Hêng is the hexagram of what lasts — and its first teaching is that lasting is not standing still. Thunder and wind endure precisely by moving: a self-renewing cycle, ceaselessly active, constant only in its direction. Where the previous hexagram showed attraction's beginning, this is the marriage: union as an enduring institution, and character as an enduring work.

The Judgment therefore couples duration with movement — it furthers to have somewhere to go. What endures is not the frozen but the continually renewed: the path walked daily, the principles reapplied to each new circumstance, the end that begins again.

Duration is the self-consistency of the person: staying true to oneself and one's path through adversity and change alike. It asks for patience with the long road, persistence through setbacks, and the humility to adapt methods while never adapting direction — for the constancy is in the aim, not the posture. Change is not duration's enemy but its medium; the enduring embrace it and move with it, as thunder moves with wind.

Tradition lives by the same law: what the generations hand down endures only in being renewed by each one that receives it.

Duration has two impostors. Rigidity: clinging to forms, habits, and grievances and calling the stiffness constancy — but what cannot bend holds no course in weather. And restlessness: the perpetual seeker, always beginning, never continuing, whose only enduring condition is agitation. Between them stands the real thing — a direction held so deeply that everything else can flex around it.
