艮

• Verb: To halt, stop, restrain, delimit, or guard.
• Noun: A mountain, boundary stone, threshold, or gate. May refer to extremities (e.g., fingers) or the final product of growth (e.g., fruit).
• State/Adjective: Still, firm, resolute, settled, or capped.
• Technical: The trigram ☶ or hexagram ䷳.

• Can function transitively (restraining a process) or intransitively (coming to a rest).
• In technical or divinatory contexts, it often serves as a marker of transition, signaling that further movement in the current direction is counterproductive.

• Stillness vs. Inertia: Denotes "active stillness"—the deliberate choice to stop at a boundary to define a shape or complete a phase—rather than passive inactivity.
• Stop vs. Block: Generally leans toward completion and timely alternation; it suggests the natural conclusion of a cycle rather than an accidental interruption.
• Firmness vs. Rigidity: Stability is structural (like a mountain) rather than brittle, providing the necessary base or capstone for a process to be considered whole.

In its trigram form (☶), one firm line rests above two yielding lines, creating the geometry of a capstone where continuation reaches a point of settlement or completion.

Be alert for "threshold imagery" in poetic or esoteric passages; this may include associations with gates, watchmen, paths, small stones, or dogs.
