Yilin Verse
阨窮上通，與堯相逢。登升大麓，國無凶人。
From dire straits one breaks through to the heights, and meets with Yao himself. Ascending the great mountain -- no wicked person remains in the realm.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder erupts from the earth as one who was trapped in dire straits breaks through to the heights. The verse names Emperor Yao directly: from poverty and constriction, one ascends to meet the sage-king himself. 'Ascending the Great Forest' recalls Shun's trial — tested in the Great Forest by Yao before receiving the throne, as recorded in the Shiji. The state is purged of evil, and peace reigns. From Enthusiasm to Keeping Still, the transformation captures the summit after the climb. The doubled mountain stands firm once the peak is reached. The enthusiast's upward burst resolves into stillness — not the stillness of stagnation but of one who has arrived and now rests in the position that was always destined.
