57 · Xun · The Gentle Wind

The Gentle (Penetrating) signifies entering: there is slight success. It is favorable to have somewhere to go. It is favorable to see the great man. The Tuan says: Redoubled penetration, by which commands are reiterated. The firm penetrates into the central and correct place, and its will is carried out. The yielding all yield obedience to the firm.

The *Shuogua* states that "Xun represents wind." When the wind moves, there is nothing it does not enter and nothing it does not penetrate.

58 · Dui · The Joyous Lake

The Joyous. Success. Perseverance is favorable. The Commentary says: Tui means joy. Firm within and yielding without—joyous, and favorable to perseverance. Thus one accords with heaven and answers to men. When one leads the people with joy, they forget their toil; when one faces danger with joy, they forget death.

What the 综卦 relation actually says

The local structured corpus records Hexagram 57's 综卦 (zong gua, inverse) as Hexagram 58, and Hexagram 58's inverse as Hexagram 57. In the corpus's stored six-line sequence, 011011 becomes 110110 when the order is reversed. Turning the figure end for end changes line positions while preserving each line's yin or yang polarity.

Reverse, compare, then test

Draw 011011 and 110110 in two columns, reverse the first sequence, and verify the match. Then copy one concrete phrase from the reference layer for Xun and one from Dui; name one observable condition supporting each lens, choose one reversible check, and write what evidence would make you review the choice.

Common misread to avoid

A zong gua pair is not a before-and-after promise. Xun does not automatically become Dui; reversed structure neither ranks the two figures nor says which one must follow.

Source boundary

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.
