Commentary

Thunder above heaven builds a house upon the water — a structure balanced on the edge of a single tooth, precarious beyond reason. The verse warns: if one fails to relocate during the yin-earth and yang-wood periods (chou and yin), then by the wood-yang and earth-yin periods (chen and mao) disaster arrives. The calendrical specificity suggests a divination concerning timing: there is a narrow window for action, and missing it means ruin. From Great Power to the Clinging, doubled fire in Li illuminates with brilliant clarity but also exposes every flaw. The transformation reveals that building power on unstable foundations is like constructing over water — the very light that should guide reveals the absurdity of the enterprise. Clarity without structural soundness is merely a brighter view of the coming collapse.
