Compare Hexagram 35 Jin (Progress) and Hexagram 36 Ming Yi (Darkening of the Light) as a zong gua inverse pair: reversed line order changes viewing direction without forecasting a transition.
Progress. The prosperous prince is presented with many horses by the Son of Heaven, and in a single day is received thrice in audience. The Tuan says: Progress means advancing, as brightness emerges above the earth.
The hexagram Jin means "advance," and this meaning lies in its image of the sun rising above the earth. The sun's ascent is always gradual, rising gently and yielding as it moves upward.
Ming I. Brightness wounded: it furthers one to be persevering in adversity. The Image says: The light has sunk into the earth — this is Ming I. Inwardly clear and outwardly yielding, thus enduring great calamity: such was King Wen. "It furthers one to be persevering in adversity" — he veils his light.
The hexagram Mingyi uses the concise judgment "favorable in difficulty and perseverance" to illustrate the virtues and methods one should uphold when caught in adversity.
The local structured corpus records Hexagram 35's 综卦 (zong gua, inverse) as Hexagram 36, and Hexagram 36's inverse as Hexagram 35. In the corpus's stored six-line sequence, 101000 becomes 000101 when the order is reversed. Turning the figure end for end changes line positions while preserving each line's yin or yang polarity.
Draw 101000 and 000101 in two columns, reverse the first sequence, and verify the match. Then copy one concrete phrase from the reference layer for Jin and one from Ming Yi; name one observable condition supporting each lens, choose one reversible check, and write what evidence would make you review the choice.
A zong gua pair is not a before-and-after promise. Jin does not automatically become Ming Yi; reversed structure neither ranks the two figures nor says which one must follow.
The reference layers and the zong-gua relationship come from Yarrow's bundled structured Zhouyi corpus. The English wording is an editorial explanation of that stored relation. This note is not a fresh cast, a forecast, or a claim that one hexagram must turn into the other.
