Gǔ (蠱) — Work on the Decayed

Mountain above Wind — decay at the roots, the damage done by neglect over time. "Before the starting point, three days; after the starting point, three days." The formula is specific: acknowledge the problem, understand how it developed, then fix it methodically. Not every problem is crisis; some are just maintenance deferred past the easy point. The work here is real but the situation is not hopeless.
