大過 → 恆

Commentary

Lake over wind steadies into thunder above wind — Duration, the hexagram of constancy and steady enterprise. One should travel to trade at the market, for whatever is gathered will be doubled. Carrying joy and embracing a child, one trades alongside profit. The verse is a merchant's blessing: go to market, and your investment will return twofold. The image of holding a child while trading suggests that commercial success and domestic happiness arise together. From Great Exceeding to Duration, the collapsing beam finds its remedy in persistent, rhythmic effort. Thunder and wind reinforce each other endlessly — the steady cycle of buying and selling, departure and return, that creates lasting prosperity. Excess is tamed not by restriction but by channeling it into reliable, repeating patterns of productive exchange.
