Commentary

Lake upon earth transforms into doubled water, the Abysmal depths of flowing commerce. The original verse reads: the Yangtze, the Yellow River, the Huai, and the sea are heaven's great marketplaces. Merchants receive blessings, and the state grows wealthy. These four waterways, the ancient Four Great Rivers, constituted the arterial network of Han dynasty commerce. Where water converges, trade converges; where trade converges, wealth accumulates. The verse celebrates the natural synergy between hydrology and economy. From Gathering to the Abysmal, the transformation shows gathering refined into flow: the still lake upon earth becomes coursing water upon water. What was static assembly becomes dynamic circulation, and the gathered community prospers precisely because it keeps moving.
