This captures what Zhou Dynasty diviners called Xun (巽), the doubled Wind trigram—gentle penetration. Wind above, wind below: subtle force working through the smallest openings. The ancient character 巽 shows a person kneeling in submission, suggesting influence through yielding rather than assertion. Where hexagram 51's doubled Thunder shocks with sudden power, Xun works gradually, the way Constable's wind sculpts clouds or air seeps through cracks stone cannot stop. Ancient practitioners saw this configuration when circumstances required tact, when transformation demanded patience, when forceful action would shatter what gentle persistence might shape. Constable made dozens of cloud studies in Hampstead Heath to understand atmospheric phenomena scientifically. This oil sketch depicts wind's invisible movement shaping clouds through gradual, continuous pressure. The Gentle (Sun) represents subtle penetration—air currents slowly forming and reforming vapors without force. The Judgment speaks to Constable's scientific method: "Small success. It furthers one to have somewhere to go. It furthers one to see the great man." The painter returned to Hampstead Heath repeatedly, studying the same phenomena from different angles. Zhou court diviners associated Xun with wood and growth—not the thunder-crack of sprouting, but the slow work of roots finding pathways through soil. Wind bends trees without breaking them, enters buildings through gaps no eye can see. The Image Text offers unexpected counsel: "Winds following one upon the other: the image of the Gently Penetrating. Thus the superior one spreads commands abroad and carries out undertakings." Constable's clouds demonstrate this principle—each gust builds on the previous one, cumulative pressure creating forms that individual gusts could never shape. In the I-Ching sequence, Xun follows hexagram 56's Wanderer: after displacement comes the work of gradually re-establishing influence, seeping back into spaces through persistent, humble attention to small openings.
