Yilin Verse
體重飛難，不得踰關，不離室垣。
The body is heavy, flight is difficult; one cannot cross the pass, cannot leave the courtyard wall.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
A spring beneath the mountain is trapped by its own weight. The body is too heavy to fly; one cannot cross the pass, cannot leave the courtyard wall. Three images of confinement compress into a single condition: heaviness, the barrier, and the enclosure. There is no villain, no storm — only the inert mass of one's own limitations. From Youthful Folly to the Marrying Maiden, the transformation adds a layer of domestic captivity. Thunder above the lake signals a hasty, perhaps ill-considered union; 'knowing the flaws from the start' is the hexagram's counsel. The naif who cannot even leave the yard has entered an arrangement from which escape is physically impossible. The walls are not high; the body is simply too heavy to clear them.
