Yilin Verse
封豕溝瀆，水潦空谷；客止舍宿，泥塗至腹。處無黍稷。
The great boar roots in the ditch; floodwater fills the hollow valley. The traveler halts to lodge for the night; mud rises to his belly. There is no millet or grain.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Heaven above the lake, yet the traveler sinks into a flooded wasteland. A monstrous boar wallows in the ditches, rainwater fills the empty valleys, and the traveler must halt for the night with mud reaching his belly. There is no millet or grain to eat. The image is desolation compounded: swine roaming through waterlogged ruins, the land producing nothing, the body mired halfway to drowning. From Treading to Enthusiasm, thunder breaks from the earth — but here the promise of joyful arousal rings hollow against the verse's misery. The transformation suggests that only a radical eruption of energy, a thunderclap of renewal, can break this paralysis of mud and hunger.
