履 → 小過

Commentary

Heaven above the lake, yet even the keenest vision has its limits. One gazes a thousand li into the distance but cannot discern a speck. Li Lou's legendary eyesight — he who could see the tip of an autumn hair at a hundred paces — adds nothing to the light itself. The allusion comes from Mencius: 'With Li Lou's sight and Gongshu Ban's skill, without compass and square one cannot make circles and squares.' Supreme ability without the right framework is useless. From Treading to Small Exceeding, thunder rumbles above the mountain. The small bird flies too high and loses its way — exceeding one's proper measure. The verse warns that extraordinary perception without proper method illuminates nothing.
