Yilin Verse
江河海隅，眾利聚居；可以遨遊，卒歲無憂。
Rivers, seas, and coastal inlets, where many advantages gather; one may wander at ease, ending the year without worry.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Wind beneath the mountain reaches the sea, and the transformation blazes as thunder and lightning together — the magnificent Abundance of Feng. Rivers and ocean margins gather all manner of wealth; communities cluster where profits congregate. One may wander freely, ending the year without care. The verse paints commercial prosperity: the confluence of rivers and seas creates natural trading hubs where goods and people accumulate. From Work on the Decayed to Abundance, the corrupted inland gives way to the teeming coast. Thunder and lightning arrive simultaneously — the peak moment of fullness. The sage uses this brilliance to render judgment and execute justice, for abundance without governance is merely chaos wearing a prosperous mask.
