Yilin Verse
三塗五岳，陽城太室。神明所扶，獨无兵革。
The Three Passes and Five Sacred Peaks; Yangcheng and the Grand Chamber. What the spirits protect; alone it is spared from war and weapons.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Fire beneath the earth meets doubled thunder — the Arousing, sudden awakening that shakes the ground. The verse invokes sacred geography: 'Santu, the Five Sacred Mountains, Yangcheng, and Taishi.' These are the central geographic features of the Zhou heartland — Santu (Three Roads) marks a strategic pass near Luoyang, while Taishi is the great hall of Mount Song, the Central Sacred Mountain. 'Protected by the spirits and gods, alone spared from war.' These sacred sites exist under divine protection, immune to the violence engulfing the world around them. From Darkening of the Light to the Arousing, the transformation suggests that even when thunder shakes everything, certain sanctified spaces remain inviolate — not through human defense but through accumulated spiritual authority.
