Commentary

Water over lake measures what can be endured, and this verse measures the limits of cold. Ice accumulates without warmth; the northern frontier is bitterly frigid. Sleeping exposed to wind and frost, the gentleman's heart aches. The verse conjures the experience of military exile or forced garrison duty on the empire's frozen northern edge — a place where limitation is not philosophical but physical, imposed by nature itself. From Limitation to Decrease, the transformation strips away what little remained. The mountain drains the lake below — diminishment from above, loss compounding loss. What was already frozen now suffers further reduction. Yet Decrease also counsels restraining anger and suppressing desire; the gentleman in the frozen wasteland practices this involuntarily, his very hardship becoming a form of spiritual discipline.
