Teach It to a Friend, Then Practice It Together
Read Hexagram 58 Dui through two joined lakes, then turn solitary consumption into mutual explanation, questioning, and applied practice.

Hexagram 58 · Dui · The Joyous Lake
This page studies a supplied Xiang image. It does not claim this hexagram was cast for the modern scene.
Source image
Two lakes touch and exchange water, each remaining distinct while refreshing the other through connection.
Concrete tension
An idea has been highlighted and saved, but nobody can yet explain it clearly or apply it to a real example.
Visible modern action
Set a 20-minute pair session. Person A explains one idea in five minutes, Person B asks one genuine question, and together they apply it to one current example; then switch roles.
Why this action comes from this source
Joined lakes become mutual discussion and practice in the source. Alternating explanation, questioning, and application requires both friends to give and receive, so the scene cannot be reduced to passive socializing.
Reflection question
Which idea can you teach and practice with one friend this week?
Audience value
Caring: both friends receive attention, a real question, and a turn to teach instead of being ranked by who already knows more.
Source boundary
The Chinese quotation is checked against Yarrow's bundled Yang Tiancai and Zhang Shanwen source text. Where that OCR witness substitutes a character, the page discloses the raw reading and checks the correction against a second classical witness. The English translation, objects, tension, and action are modern Yarrow editorial work. This is not a fresh cast, prediction, or promised outcome.
